It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies). - -Dear ImGui is designed to enable fast iteration and empower programmers to create content creation tools and visualization/ debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and thus lacks certain features normally found in more high-level libraries. - -Dear ImGui is particularly suited to integration in realtime 3D applications, fullscreen applications, embedded applications, games, or any applications on consoles platforms where operating system features are non-standard. - -Dear ImGui is self-contained within a few files that you can easily copy and compile into your application/engine: - - - imgui.cpp - - imgui.h - - imgui_demo.cpp - - imgui_draw.cpp - - imgui_internal.h - - imconfig.h (empty by default, user-editable) - - stb_rect_pack.h - - stb_textedit.h - - stb_truetype.h - -No specific build process is required. You can add the .cpp files to your project or #include them from an existing file. - -Your code passes mouse/keyboard inputs and settings to Dear ImGui (see example applications for more details). After Dear ImGui is setup, you can use it like in this example: - -![screenshot of sample code alongside its output with dear imgui](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/code_sample_01.png) - -Dear ImGui outputs vertex buffers and simple command-lists that you can render in your application. The number of draw calls and state changes is typically very small. Because it doesn't know or touch graphics state directly, you can call ImGui commands anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase. - -_A common misunderstanding is to think that immediate mode gui == immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes, as the gui functions are called by the user. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._ - -Dear ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc. - -Demo Binaries -------------- - -You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here: -- [imgui-demo-binaries-20180207.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20180207.zip) (Windows binaries, Dear ImGui 1.60 WIP built 2018/01/07, 5 executables) - -The demo applications are unfortunately not yet DPI aware so expect some blurryness on a 4K screen. - -Bindings --------- - -Integrating Dear ImGui within your custom engine is a matter of wiring mouse/keyboard inputs and providing a render function that can bind a texture and render simple textured triangles. The examples/ folder is populated with applications doing just that. If you are an experienced programmer it should take you less than an hour to integrate Dear ImGui in your custom engine, but make sure to spend time reading the FAQ, the comments and other documentation! - -_NB: those third-party bindings may be more or less maintained, more or less close to the spirit of original API and therefore I cannot give much guarantee about them. People who create language bindings sometimes haven't used the C++ API themselves (for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use.

This is mainly because "Retained Mode" GUIs have been so widespread and predominant. The following links can give you a better understanding about how Immediate Mode GUIs works. -- [Johannes 'johno' Norneby's article](http://www.johno.se/book/imgui.html). -- [A presentation by Rickard Gustafsson and Johannes Algelind](http://www.cse.chalmers.se/edu/year/2011/course/TDA361/Advanced%20Computer%20Graphics/IMGUI.pdf). -- [Jari Komppa's tutorial on building an ImGui library](http://iki.fi/sol/imgui/). -- [Casey Muratori's original video that popularized the concept](https://mollyrocket.com/861). -- [Nicolas Guillemot's CppCon'16 flashtalk about Dear ImGui](https://www.youtube.com/watch?v=LSRJ1jZq90k). -- [Thierry Excoffier's Zero Memory Widget](http://perso.univ-lyon1.fr/thierry.excoffier/ZMW/). - -See the [Software using dear imgui page](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) for an incomplete list of software which are publicly known to use dear migui. - -See the [Links page](https://github.com/ocornut/imgui/wiki/Links) for third-party bindings to different languages and frameworks. - -Frequently Asked Question (FAQ) -------------------------------- - -Where is the documentation? - -- The documentation is at the top of imgui.cpp + effectively imgui.h. -- Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. -- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder. -- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort. - -Which version should I get? - -I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master. The library is fairly stable and regressions tend to be fixed fast when reported. - -Why the odd dual naming, "dear imgui" vs "ImGui"? - -The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations. - -How can I help? -
How can I display an image? What is ImTextureID, how does it works? -
How can I have multiple widgets with the same label, or without any label? (Yes). A primer on labels and ID stack. -

How can I load a different font than the default? -
How can I easily use icons in my application? -
How can I load multiple fonts? -
How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic? -
How can I preserve my Dear ImGui context across reloading a DLL? (loss of the global/static variables) -
How can I use the drawing facilities without an Dear ImGui window? (using ImDrawList API) -
I integrated Dear ImGui in my engine and the text or lines are blurry.. -
I integrated Dear ImGui in my engine and some elements are disappearing when I move windows around.. - -See the FAQ in imgui.cpp for answers. - -How do you use Dear ImGui on a platform that may not have a mouse or keyboard? - -You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.NavFlags |= ImGuiNavFlags_EnableGamepad`). - -You can share your computer mouse seamlessy with your console/tablet/phone using [Synergy](http://synergy-project.org) ([sources](https://github.com/symless/synergy)). This is the prefered solution for developer productivity. In particular, their [micro-synergy-client](https://github.com/symless/micro-synergy-client) repo there is _uSynergy.c_ sources for a small embeddable that you can use on any platform to connect to your host PC. You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui). - -For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimising for screen real-estate and precision. - -Can you create elaborate/serious tools with Dear ImGui? - -Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library. - -Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful. - -Is Dear ImGui fast? - -Probably fast enough for most uses. Down to the foundation of its visual design, Dear ImGui is engineered to be fairly performant both in term of CPU and GPU usage. Running elaborate code and creating elaborate UI will of course have a cost but Dear ImGui aims to minimize it. - -Mileage may vary but the following screenshot can give you a rough idea of the cost of running and rendering UI code (In the case of a trivial demo application like this one, your driver/os setup are likely to be the bottleneck. Testing performance as part of a real application is recommended). - -![performance screenshot](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v138/performance_01.png) - -This is showing framerate for the full application loop on my 2011 iMac running Windows 7, OpenGL, AMD Radeon HD 6700M with an optimized executable. In contrast, librairies featuring higher-quality rendering and layouting techniques may have a higher resources footprint. - -If you intend to display large lists of items (say, 1000+) it can be beneficial for your code to perform clipping manually - one way is using helpers such as ImGuiListClipper - in order to avoid submitting them to Dear ImGui in the first place. Even though ImGui will discard your clipped items it still needs to calculate their size and that overhead will add up if you have thousands of items. If you can handle clipping and height positionning yourself then browsing a list with millions of items isn't a problem. - -Can you reskin the look of Dear ImGui? - -You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged): - -![LumixEngine](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v151/lumix-201710-rearranged.png) - -Why using C++ (as opposed to C)? - -Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience. - -There is an reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly designed for binding in other languages. I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use.

The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com). - -I first discovered imgui principles at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple imgui implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating on it. - -Embeds [ProggyClean.ttf](http://upperbounds.net) font by Tristan Grimmer (MIT license). - -Embeds [stb_textedit.h, stb_truetype.h, stb_rectpack.h](https://github.com/nothings/stb/) by Sean Barrett (public domain). - -Inspiration, feedback, and testing for early versions: Casey Muratori, Atman Binstock, Mikko Mononen, Emmanuel Briney, Stefan Kamoda, Anton Mikhailov, Matt Willis.

If you were conveniently using the imgui copy of those + STB headers in your project, you will have to update your include paths. (#1718, #2036) + The reason for this change is to avoid conflicts for projects that may also be importing + their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified. +- Renamed io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + +Other Changes: + +- This is a minor release following the 1.64 refactor, with a little more shuffling of code. +- Clarified and improved the source code sectioning in all files (easier to search or browse sections). +- Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system. + Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787) +- Fixed a build issue with non-Cygwin GCC under Windows. +- Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent. +- Examples: OpenGL3+SDL2: Fixed error condition when using the GLAD loader. (#2059, #2002) [@jiri] + + +----------------------------------------------------------------------- + VERSION 1.64 (Released 2018-08-31) +----------------------------------------------------------------------- + +Changes: + +- Moved README, CHANGELOG and TODO files to the docs/ folder. + If you are updating dear imgui by copying files, take the chance to delete the old files. +- Added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. + Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTIONS HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. + If you have any modifications to imgui.cpp, it is suggested that you first update to 1.63, then + isolate your patches. You can peak at imgui_widgets.cpp from 1.64 to get a sense of what is included in it, + then separate your changes into several patches that can more easily be applied to 1.64 on a per-file basis. + What I found worked nicely for me, was to open the diff of the old patches in an interactive merge/diff tool, + search for the corresponding function in the new code and apply the chunks manually. +- As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github, + so a solution applicable on the Master branch can be found. If your company has changes that you cannot + disclose you may also contact me privately. + + +----------------------------------------------------------------------- + VERSION 1.63 (Released 2018-08-29) +----------------------------------------------------------------------- + +Breaking Changes: + +- Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). +- Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecision over time. +- Removed per-window ImGuiWindowFlags_ResizeFromAnySide Beta flag in favor `io.ConfigResizeWindowsFromEdges=true` to enable the feature globally. (#1495) + The feature is not currently enabled by default because it is not satisfying enough, but will eventually be. +- InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. + Kept redirection types (will obsolete). +- InputText: Removed ImGuiTextEditCallbackData::ReadOnly since it is a duplication of (ImGuiTextEditCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). +- Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. + Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). +- Renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to io.ConfigMacOSXBehaviors for consistency. (#1427, #473) +- Removed obsolete redirection functions: CollapsingHeader() variation with 2 bools - marked obsolete in v1.49, May 2016. + +Other Changes: + +- ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat). +- ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly. +- Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. The change is motivated by upcoming Docking features. (#787) +- Nav: Made CTRL+TAB skip menus + skip the current navigation window if is has the ImGuiWindow_NoNavFocus set. (#787) + While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the ImGuiWindow_NoNavFocus flag. +- Window: Allow menu and popups windows from ignoring the style.WindowMinSize values so short menus/popups are not padded. (#1909) +- Window: Added global io.ConfigResizeWindowsFromEdges option to enable resizing windows from their edges and from the lower-left corner. (#1495) +- Window: Collapse button shows hovering highlight + clicking and dragging on it allows to drag the window as well. +- Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool returned by most widgets. + It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034) +- InputText: Added support for buffer size/capacity changes via the ImGuiInputTextFlags_CallbackResize flag. (#2006, #1443, #1008). +- InputText: Fixed not tracking the cursor horizontally when modifying the text buffer through a callback. +- InputText: Fixed minor off-by-one issue when submitting a buffer size smaller than the initial zero-terminated buffer contents. +- InputText: Fixed a few pathological crash cases on single-line InputText widget with multiple millions characters worth of contents. + Because the current text drawing function reserve for a worst-case amount of vertices and how we handle horizontal clipping, + we currently just avoid displaying those single-line widgets when they are over a threshold of 2 millions characters, + until a better solution is found. +- Drag and Drop: Fixed an incorrect assert when dropping a source that is submitted after the target (bug introduced with 1.62 changes + related to the addition of IsItemDeactivated()). (#1875, #143) +- Drag and Drop: Fixed ImGuiDragDropFlags_SourceNoDisableHover to affect hovering state prior to calling IsItemHovered() + fixed description. (#143) +- Drag and Drop: Calling BeginTooltip() between a BeginDragSource()/EndDragSource() or BeginDropTarget()/EndDropTarget() uses adjusted tooltip + settings matching the one created when calling BeginDragSource() without the ImGuiDragDropFlags_SourceNoPreviewTooltip flag. (#143) +- Drag and Drop: Payload stays available and under the mouse if the source stops being submitted, however the tooltip is replaced by "...". (#1725) +- Drag and Drop: Added ImGuiDragDropFlags_SourceAutoExpirePayload flag to force payload to expire if the source stops being submitted. (#1725, #143). +- IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211) +- Selectable: Added ImGuiSelectableFlags_Disabled flag in the public API. (#211) +- ColorEdit4: Fixed a bug when text input or drag and drop leading to unsaturated HSV values would erroneously alter the resulting color. (#2050) +- Misc: Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2006, #1443, #1008) + [*EDIT* renamed to misc/std/imgui_stdlib.h in 1.66] +- Misc: Added IMGUI_VERSION_NUM for easy compile-time testing. (#2025) +- Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut] +- Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors. +- Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987) +- Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). (#2023, #820, #956, #1875). +- Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive). +- Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502) +- Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276) +- ImDrawList: Improved handling for worst-case vertices reservation policy when large amount of text (e.g. 1+ million character strings) + are being submitted in a single call. It would typically have crashed InputTextMultiline(). (#200) +- OS/Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby] +- Metrics: Changed io.MetricsActiveWindows to reflect the number of active windows (!= from visible windows), which is useful + for lazy/idle render mechanisms as new windows are typically not visible for one frame. +- Metrics: Added io.MetricsRenderWindow to reflect the number of visible windows. +- Metrics: Added io.MetricsActiveAllocations, moving away from the cross-context global counters than we previously used. (#1565, #1599, #586) +- Demo: Added basic Drag and Drop demo. (#143) +- Demo: Modified the Console example to use InsertChars() in the input text callback instead of poking directly into the buffer. + Although this won't make a difference in the example itself, using InsertChars() will honor the resizing callback properly. (#2006, #1443, #1008). +- Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section. +- Examples: Tweaked the main.cpp of each example. +- Examples: Metal: Added Metal rendering backend. (#1929, #1873) [@warrenm] +- Examples: OSX: Added early raw OSX platform backend. (#1873) [@pagghiu, @itamago, @ocornut] +- Examples: Added mac OSX & iOS + Metal example in example_apple_metal/. (#1929, #1873) [@warrenm] +- Examples: Added mac OSX + OpenGL2 example in example_apple_opengl2/. (#1873) +- Examples: OpenGL3: Added shaders more versions of GLSL. (#1938, #1941, #1900, #1513, #1466, etc.) +- Examples: OpenGL3: Tweaked the imgui_impl_opengl3.cpp to work as-is with Emscripten + WebGL 2.0. (#1941). [@o-micron] +- Examples: OpenGL3: Made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac. +- Examples: OpenGL3: Added error output when shaders fail to compile/link. +- Examples: OpenGL3: Added support for glew and glad OpenGL loaders out of the box. (#2001, #2002) [@jdumas] +- Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996) +- Examples: DirectX10, DirectX11: Fixed unreleased resources in Init and Shutdown functions. (#1944) +- Examples: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility. (#1989) [@matt77hias] +- Examples: Vulkan: Fixed handling of VkSurfaceCapabilitiesKHR::maxImageCount = 0 case. Tweaked present mode selections. +- Examples: Win32, Glfw, SDL: Added support for the ImGuiMouseCursor_Hand cursor. + + +----------------------------------------------------------------------- + VERSION 1.62 (Released 2018-06-22) +----------------------------------------------------------------------- + +Breaking Changes: + +- TreeNodeEx(): The helper ImGuiTreeNodeFlags_CollapsingHeader flag now include ImGuiTreeNodeFlags_NoTreePushOnOpen. The flag was already set by CollapsingHeader(). + The only difference is if you were using TreeNodeEx() manually with ImGuiTreeNodeFlags_CollapsingHeader and without ImGuiTreeNodeFlags_NoTreePushOnOpen. + In this case you can remove the ImGuiTreeNodeFlags_NoTreePushOnOpen flag from your call (ImGuiTreeNodeFlags_CollapsingHeader & ~ImGuiTreeNodeFlags_NoTreePushOnOpen). (#1864) + This also apply if you were using internal's TreeNodeBehavior() with the ImGuiTreeNodeFlags_CollapsingHeader flag directly. +- ImFontAtlas: Renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish new smaller variants and discourage using the full set. (#1859) + +Other Changes: + +- Examples back-ends have been refactored to separate the platform code (e.g. Win32, Glfw, SDL2) from the renderer code (e.g. DirectX11, OpenGL3, Vulkan). + The "Platform" bindings are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, etc. + The "Renderer" bindings are in charge of: creating the main font texture, rendering imgui draw data. + before: imgui_impl_dx11.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx11.cpp + before: imgui_impl_dx12.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx12.cpp + before: imgui_impl_glfw_gl3.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp + before: imgui_impl_glfw_vulkan.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_vulkan.cpp + before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl2.cpp + before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl3.cpp etc. + - The idea is what we can now easily combine and maintain back-ends and reduce code redundancy. Individual files are smaller and more reusable. + Integration of imgui into a new/custom engine may also be easier as there is less overlap between "windowing / inputs" and "rendering" code, + so you may study or grab one half of the code and not the other. + - This change was motivated by the fact that adding support for the upcoming multi-viewport feature requires more work from the Platform and Renderer + back-ends, and the amount of redundancy across files was becoming too difficult to maintain. If you use default back-ends, you'll benefit from an + easy update path to support multi-viewports later (for future ImGui 1.7x). + - This is not strictly a breaking change if you keep your old bindings, but when you'll want to fully update your bindings, + expect to have to reshuffle a few things. + - Each example still has its own main.cpp which you may refer you to understand how to initialize and glue everything together. + - Some frameworks (such as the Allegro, Marmalade) handle both the "platform" and "rendering" part, and your custom engine may as well. + - Read examples/README.txt for details. +- Added IsItemDeactivated() to query if the last item was active previously and isn't anymore. Useful for Undo/Redo patterns. (#820, #956, #1875) +- Added IsItemDeactivatedAfterChange() [*EDIT* renamed to IsItemDeactivatedAfterEdit() in 1.63] if the last item was active previously, + is not anymore, and during its active state modified a value. Note that you may still get false positive (e.g. drag value and while + holding return on the same value). (#820, #956, #1875) +- Nav: Added support for PageUp/PageDown (explorer-style: first aim at bottom/top most item, when scroll a page worth of contents). (#787) +- Nav: To keep the navigated item in view we also attempt to scroll the parent window as well as the current window. (#787) +- ColorEdit3, ColorEdit4, ColorButton: Added ImGuiColorEditFlags_NoDragDrop flag to disable ColorEditX as drag target and ColorButton as drag source. (#1826) +- BeginDragDropSource(): Offset tooltip position so it is off the mouse cursor, but also closer to it than regular tooltips, and not clamped by viewport. (#1739) +- BeginDragDropTarget(): Added ImGuiDragDropFlags_AcceptNoPreviewTooltip flag to request hiding the drag source tooltip from the target site. (#143) +- BeginCombo(), BeginMainMenuBar(), BeginChildFrame(): Temporary style modification are restored at the end of BeginXXX instead of EndXXX, to not affect tooltips and child windows. +- Popup: Improved handling of (erroneously) repeating calls to OpenPopup() to not close the popup's child popups. (#1497, #1533, #1865). +- InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787) +- InputText(): Fixed Undo corruption after pasting large amount of text (Redo will still fail when undo buffers are exhausted, but text won't be corrupted). +- SliderFloat(): When using keyboard/gamepad and a zero precision format string (e.g. "%.0f"), always step in integer units. (#1866) +- ImFontConfig: Added GlyphMinAdvanceX/GlyphMaxAdvanceX settings useful to make a font appears monospaced, particularly useful for icon fonts. (#1869) +- ImFontAtlas: Added GetGlyphRangesChineseSimplifiedCommon() helper that returns a list of ~2500 most common Simplified Chinese characters. (#1859) [@JX-Master, @ocornut] +- Examples: OSX: Added imgui_impl_osx.mm binding to be used along with e.g. imgui_impl_opengl2.cpp. (#281, #1870) [@pagghiu, @itamago, @ocornut] +- Examples: GLFW: Made it possible to Shutdown/Init the backend again (by reseting the time storage properly). (#1827) [@ice1000] +- Examples: Win32: Fixed handling of mouse wheel messages to support sub-unit scrolling messages (typically sent by track-pads). (#1874) [@zx64] +- Examples: SDL+Vulkan: Added SDL+Vulkan example. +- Examples: Allegro5: Added support for ImGuiConfigFlags_NoMouseCursorChange flag. Added clipboard support. +- Examples: Allegro5: Unindexing buffers ourselves as Allegro indexed drawing primitives are buggy in the DirectX9 back-end (will be fixed in Allegro 5.2.5+). +- Examples: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from ImGui_ImplDX12_NewFrame() to ImGui_ImplDX12_RenderDrawData() which makes a lots more sense. (#301) +- Examples: Vulkan: Reordered parameters ImGui_ImplVulkan_RenderDrawData() to be consistent with other bindings, a good occasion since we refactored the code. +- Examples: FreeGLUT: Added FreeGLUT bindings. Added FreeGLUT+OpenGL2 example. (#801) +- Examples: The functions in imgui_impl_xxx.cpp are prefixed with IMGUI_IMPL_API (which defaults to IMGUI_API) to facilitate some uses. (#1888) +- Examples: Fixed bindings to use ImGuiMouseCursor_COUNT instead of old name ImGuiMouseCursor_Count_ so they can compile with IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#1887) +- Misc: Updated stb_textedit from 1.09 + patches to 1.12 + minor patches. +- Internals: PushItemFlag() flags are inherited by BeginChild(). + + +----------------------------------------------------------------------- + VERSION 1.61 (Released 2018-05-14) +----------------------------------------------------------------------- + +Breaking Changes: + +- DragInt(): The default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to you find them. +- InputFloat(): Obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). +- Misc: IM_DELETE() helper function added in 1.60 doesn't set the input pointer to NULL, more consistent with standard expectation and allows passing r-values. + +Other Changes: + +- Added DragScalar, DragScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011) +- Added InputScalar, InputScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011) +- Added SliderScalar, SliderScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011) +- Window: Fixed pop-ups/tooltips/menus not honoring style.DisplaySafeAreaPadding as well as it should have (part of menus displayed outside the safe area, etc.). +- Window: Fixed windows using the ImGuiWindowFlags_NoSavedSettings flag from not using the same default position as other windows. (#1760) +- Window: Relaxed the internal stack size checker to allow Push/Begin/Pop/.../End patterns to be used with PushStyleColor, PushStyleVar, PushFont without causing a false positive assert. (#1767) +- Window: Fixed the default proportional item width lagging by one frame on resize. +- Columns: Fixed a bug introduced in 1.51 where columns would affect the contents size of their container, often creating feedback loops when ImGuiWindowFlags_AlwaysAutoResize was used. (#1760) +- Settings: Fixed saving an empty .ini file if CreateContext/DestroyContext are called without a single call to NewFrame(). (#1741) +- Settings: Added LoadIniSettingsFromDisk(), LoadIniSettingsFromMemory(), SaveIniSettingsToDisk(), SaveIniSettingsToMemory() to manually load/save .ini settings. (#923, #993) +- Settings: Added io.WantSaveIniSettings flag, which is set to notify the application that e.g. SaveIniSettingsToMemory() should be called. (#923, #993) +- Scrolling: Fixed a case where using SetScrollHere(1.0f) at the bottom of a window on the same frame the window height has been growing would have the scroll clamped using the previous height. (#1804) +- MenuBar: Made BeginMainMenuBar() honor style.DisplaySafeAreaPadding so the text can be made visible on TV settings that don't display all pixels. (#1439) [@dougbinks] +- InputText: On Mac OS X, filter out characters when the CMD modifier is held. (#1747) [@sivu] +- InputText: On Mac OS X, support CMD+SHIFT+Z for Redo. CMD+Y is also supported as major apps seems to default to support both. (#1765) [@lfnoise] +- InputText: Fixed returning true when edition is cancelled with ESC and the current buffer matches the initial value. +- InputFloat,InputFloat2,InputFloat3,InputFloat4: Added variations taking a more flexible and consistent optional "const char* format" parameter instead of "int decimal_precision". + This allow using custom formats to display values in scientific notation, and is generally more consistent with other API. Obsoleted functions using the optional "int decimal_precision" parameter. (#648) +- DragFloat, DragInt: Cancel mouse tweak when current value is initially past the min/max boundaries and mouse is pushing in the same direction (keyboard/gamepad version already did this). +- DragFloat, DragInt: Honor natural type limits (e.g. INT_MAX, FLT_MAX) instead of wrapping around. (#708, #320) +- DragFloat, SliderFloat: Fixes to allow input of scientific notation numbers when using CTRL+Click to input the value. (~#648, #1011) +- DragFloat, SliderFloat: Rounding-on-write uses the provided format string instead of parsing the precision from the string, which allows for finer uses of %e %g etc. (#648, #642) +- DragFloat: Improved computation when using the power curve. Improved lost of input precision with very small steps. Added an assert than power-curve requires a min/max range. (~#642) +- DragFloat: The 'power' parameter is only honored if the min/max parameter are also setup. +- DragInt, SliderInt: Fixed handling of large integers (we previously passed data around internally as float, which reduced the range of valid integers). +- ColorEdit: Fixed not being able to pass the ImGuiColorEditFlags_NoAlpha or ImGuiColorEditFlags_HDR flags to SetColorEditOptions(). +- Nav: Fixed hovering a Selectable() with the mouse so that it update the navigation cursor (as it happened in the pre-1.60 navigation branch). (#787) +- Style: Changed default style.DisplaySafeAreaPadding values from (4,4) to (3,3) so it is smaller than FramePadding and has no effect on main menu bar on a computer. (#1439) +- Fonts: When building font atlas, glyphs that are missing in the fonts are not using the glyph slot to render a dummy/default glyph. Saves space and allow merging fonts with + overlapping font ranges such as FontAwesome5 which split out the Brands separately from the Solid fonts. (#1703, #1671) +- Misc: Added IMGUI_CHECKVERSION() macro to compare version string and data structure sizes in order to catch issues with mismatching compilation unit settings. (#1695, #1769) +- Misc: Added IMGUI_DISABLE_MATH_FUNCTIONS in imconfig.h to make it easier to redefine wrappers for std/crt math functions. +- Misc: Fix to allow compiling in unity builds where stb_rectpack/stb_truetype may be already included in the same compilation unit. +- Demo: Simple Overlay: Added a context menu item to enable freely moving the window. +- Demo: Added demo for DragScalar(), InputScalar(), SliderScalar(). (#643) +- Examples: Calling IMGUI_CHECKVERSION() in the main.cpp of every example application. +- Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unnecessary conversion (Allegro 5 doesn't support 16-bit indices). +- Examples: Allegro 5: Renamed bindings from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp. +- Examples: DirectX 9: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud. (#1790, #1687) [@sr-tream] +- Examples: SDL: Fixed clipboard paste memory leak in the SDL binding code. (#1803) [@eliasdaler] +- Various minor fixes, tweaks, refactoring, comments. + + +----------------------------------------------------------------------- + VERSION 1.60 (Released 2018-04-07) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.60 + +The gamepad/keyboard navigation branch (which has been in the work since July 2016) has been merged. +Gamepad/keyboard navigation is still marked as Beta and has to be enabled explicitly. +Various internal refactoring have also been done, as part of the navigation work and as part of the upcoming viewport/docking work. + +VIEWPORT BRANCH +(IN PROGRESS, WILL MERGE INTO THE MAIN LISTS WHEN WE MERGE THE BRANCH) + + - Viewport: Added support for multi-viewport [...] blah blah + - Viewport: Rendering: the ImDrawData structure now contains 'DisplayPos' and 'DisplaySize' fields. To support multi-viewport, you need to use those values when + creating your orthographic projection matrix. Use 'draw_data->DisplaySize' instead of 'io.DisplaySize', and 'draw_data->DisplayPos' instead of (0,0) as the upper-left point. + You also need to subtract 'draw_data->DisplayPos' from your scissor rectangles, as scissor rectangles are specified in the space of your target viewport. + - Examples: Back-ends have been refactored to separate the platform code (e.g. Win32, Glfw, SDL2) from the renderer code (e.g. DirectX11, OpenGL3, Vulkan). + before: imgui_impl_dx11.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx11.cpp + before: imgui_impl_dx12.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx12.cpp + before: imgui_impl_glfw_gl3.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp + before: imgui_impl_glfw_vulkan.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_vulkan.cpp + before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl2.cpp + before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl3.cpp + etc. + - The idea is what we can now easily combine and maintain back-ends and reduce code redundancy.

(#1367) [@gmueckl] + - Metrics: Added a "Show window begin order" checkbox to visualize the order windows are submitted. + - Internal: Settings: Added ReadCloseFn handler to be able to patch/alter a loaded object after all the fields are known. + +Breaking Changes: + +- Obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). + e.g. with example backends, call ImDrawData* draw_data = ImGui::GetDrawData(); ImGui_ImplXXXX_RenderDrawData(draw_data). +- Reorganized context handling to be more explicit: (#1599) + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. If you are using an old backend from the examples/ folder, remove the line that calls Shutdown(). + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. +- Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. +- Fonts: Moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. +- Fonts: changed ImFont::DisplayOffset.y to defaults to 0 instead of +1. Fixed vertical rounding of Ascent/Descent to match TrueType renderer. + If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619) +- BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. +- Obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). +- Obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). +- Renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, not used by core, and honored by some binding ahead of merging the Nav branch). +- Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered style colors as the closing cross uses regular button colors now. +- Renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. +- Removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it should be easy to replicate on your side (you can find the code in 1.53). +- [EDITED] Window: BeginChild() with an explicit name doesn't include the hash within the internal window name. (#1698) + This change was erroneously introduced, undoing the change done for #894, #713, and not documented properly in the original + 1.60 release Changelog. It was fixed on 2018-09-28 (1.66) and I wrote this paragraph the same day. + +Other Changes: + +- Doc: Added a Changelog file in the repository to ease comparing versions (it goes back to dear imgui 1.48), until now it was only on GitHub. +- Navigation: merged in the gamepad/keyboard navigation (about a million changes!). (#787, #323) + The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. +- To use Gamepad Navigation: + - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). Read imgui.cpp for more details. + - See https://github.com/ocornut/imgui/issues/1599 for recommended gamepad mapping or download PNG/PSD at http://goo.gl/9LgVZW + - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. Read imgui.cpp for more details. +- To use Keyboard Navigation: + - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable. NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays. + - Basic controls: arrows to navigate, Alt to enter menus, Space to activate item, Enter to edit text, Escape to cancel/close, Ctrl-Tab to focus windows, etc. + - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag will be set. + For more advanced uses, you may want to read from io.NavActive or io.NavVisible. Read imgui.cpp for more details. +- Navigation: SetItemDefaultFocus() sets the navigation position in addition to scrolling. (#787) +- Navigation: Added IsItemFocused(), added IsAnyItemFocused(). (#787) +- Navigation: Added window flags: ImGuiWindowFlags_NoNav (== ImGuiWindowFlags_NoNavInputs | ImGuiWindowFlags_NoNavFocus). +- Navigation: Style: Added ImGuiCol_NavHighlight, ImGuiCol_NavWindowingHighlight colors. (#787) +- Navigation: TreeNode: Added ImGuiTreeNodeFlags_NavLeftJumpsBackHere flag to allow Nav Left direction to jump back to parent tree node from any of its child. (#1079) +- Navigation: IO: Added io.ConfigFlags (input), io.NavActive (output), io.NavVisible (output). (#787) +- Context: Removed the default global context and font atlas instances, which caused various problems to users of multiple contexts and DLL users. (#1565, #1599) + YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. Existing apps will assert/crash without it. +- Context: Added SetAllocatorFunctions() to rewire memory allocators (as a replacement to previous parameters to CreateContext()). Allocators are shared by all contexts and imgui helpers. (#1565, #586, #992, #1007, #1558) +- Context: You may pass a ImFontAtlas to CreateContext() to specify a font atlas to share. Shared font atlas are not owned by the context and not destroyed along with it. (#1599) +- Context: Added IMGUI_DISABLE_DEFAULT_ALLOCATORS to disable linking with malloc/free. (#1565, #586, #992, #1007, #1558) +- IO: Added io.ConfigFlags for user application to store settings for imgui and for the backend: + - ImGuiConfigFlags_NavEnableKeyboard: Enable keyboard navigation. + - ImGuiConfigFlags_NavEnableGamepad: Enable gamepad navigation (provided ImGuiBackendFlags_HasGamepad is also set by backend). + - ImGuiConfigFlags_NavEnableSetMousePos: Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward. + - ImGuiConfigFlags_NoMouseCursorChange: Instruct backend to not alter mouse cursor shape and visibility (by default the example backend use mouse cursor API of the platform when available) + - ImGuiConfigFlags_NoMouse: Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information passed by the backend. + - ImGuiConfigFlags_IsSRGB, ImGuiConfigFlags_IsTouchScreen: Flags for general application use. +- IO: Added io.BackendFlags for backend to store its capabilities (currently: _HasGamepad, _HasMouseCursors, _HasSetMousePos). This will be used more in the next version. +- IO: Added ImGuiKey_Insert, ImGuiKey_Space keys. Setup in all example bindings. (#1541) +- IO: Added Horizontal Mouse Wheel support for horizontal scrolling. (#1463) [@tseeker] +- IO: Added IsAnyMouseDown() helper which is helpful for bindings to handle mouse capturing. +- Window: Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else when dragging afterwards. (#1381, #1337) +- Window: IsWindowHovered(): Added ImGuiHoveredFlags_AnyWindow, ImGuiFocusedFlags_AnyWindow flags (See Breaking Changes). Added to demo. (#1382) +- Window: Added SetNextWindowBgAlpha() helper. Particularly helpful since the legacy 5-parameters version of Begin() has been marked as obsolete in 1.53. (#1567) +- Window: Fixed SetNextWindowContentSize() with 0.0f on Y axis (or SetNextWindowContentWidth()) overwriting the contents size. Got broken on Dec 10 (1.53). (#1363) +- ArrowButton: Added ArrowButton() given a cardinal direction (e.g. ImGuiDir_Left). +- InputText: Added alternative clipboard shortcuts: Shift+Delete (cut), CTRL+Insert (copy), Shift+Insert (paste). (#1541) +- InputText: Fixed losing Cursor X position when clicking outside on an item that's submitted after the InputText(). It was only noticeable when restoring focus programmatically. (#1418, #1554) +- InputText: Added ImGuiInputTextFlags_CharsScientific flag to also allow 'e'/'E' for input of values using scientific notation. Automatically used by InputFloat. +- Style: Default style is now StyleColorsDark(), instead of the old StyleColorsClassic(). (#707) +- Style: Enable window border by default. (#707) +- Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181) +- Style: Added style.MouseCursorScale help when using the software mouse cursor facility. (#939). +- Style: Close button nows display a cross before hovering. Fixed cross positioning being a little off. Uses button colors for highlight when hovering. (#707) +- Popup: OpenPopup() Always reopen existing pop-ups. (Removed imgui_internal.h's OpenPopupEx() which was used for this.) (#1497, #1533). +- Popup: BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick() all react on mouse release instead of mouse press. (~#439) +- Popup: Better handling of user mistakenly calling OpenPopup() every frame (with reopen_existing option). The error will now be more visible and easier to understand. (#1497) +- Popup: BeginPopup(): Exposed extra_flags parameter that are passed through to Begin(). (#1533) +- Popup: BeginPopupModal: fixed the conditional test for SetNextWindowPos() which was polling the wrong window, which in practice made the test succeed all the time. +- Tooltip: BeginTooltip() sets ImGuiWindowFlags_NoInputs flag. +- Scrollbar: Fixed ScrollbarY enable test after ScrollbarX has been enabled being a little off (small regression from Nov 2017). (#1574) +- Scrollbar: Fixed ScrollbarX enable test subtracting WindowPadding.x (this has been there since the addition of horizontal scroll bar!). +- Columns: Clear offsets data when columns count changed. (#1525) +- Columns: Fixed a memory leak of ImGuiColumnsSet's Columns vector. (#1529) [@unprompted] +- Columns: Fixed resizing a window very small breaking some columns positioning (broken in 1.53). +- Columns: The available column extent takes consideration of the right-most clipped pixel, so the right-most column may look a little wider but will contain the same amount of visible contents. +- MenuBar: Fixed menu bar pushing a clipping rect outside of its allocated bound (usually unnoticeable). +- TreeNode: nodes with the ImGuiTreeNodeFlags_Leaf flag correctly disable highlight when DragDrop is active. (#143, #581) +- Drag and Drop: Increased payload type string to 32 characters instead of 8. (#143) +- Drag and Drop: TreeNode as drop target displays rectangle over full frame. (#1597, #143) +- DragFloat: Fix/workaround for backends which do not preserve a valid mouse position when dragged out of bounds. (#1559) +- InputFloat: Allow inputing value using scientific notation e.g. "1e+10". +- InputDouble: Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. (#1011) +- Slider, Combo: Use ImGuiCol_FrameBgHovered color when hovered. (#1456) [@stfx] +- Combo: BeginCombo(): Added ImGuiComboFlags_NoArrowButton to disable the arrow button and only display the wide value preview box. +- Combo: BeginCombo(): Added ImGuiComboFlags_NoPreview to disable the preview and only display a square arrow button. +- Combo: Arrow button isn't displayed over frame background so its blended color matches other buttons. Left side of the button isn't rounded. +- PlotLines: plot a flat line if scale_min==scale_max. (#1621) +- Fonts: Changed DisplayOffset.y to defaults to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. + If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619) +- Fonts: Updated stb_truetype from 1.14 to stb_truetype 1.19. (w/ include fix from some platforms #1622) +- Fonts: Added optional FreeType rasterizer in misc/freetype. Moved from imgui_club repo. (#618) [@Vuhdo, @mikesart, @ocornut] +- Fonts: Moved extra_fonts/ to misc/fonts/. +- ImFontAtlas: Fixed cfg.MergeMode not reusing existing glyphs if available (always overwrote). +- ImFontAtlas: Handle stb_truetype stbtt_InitFont() and stbtt_PackBegin() possible failures more gracefully, GetTexDataAsRGBA32() won't crash during conversion. (#1527) +- ImFontAtlas: Moved mouse cursor data out of ImGuiContext, fix drawing them with multiple contexts. Also remove the last remaining undesirable dependency on ImGui in imgui_draw.cpp. (#939) +- ImFontAtlas: Added ImFontAtlasFlags_NoPowerOfTwoHeight flag to disable padding font height to nearest power of two. (#1613) +- ImFontAtlas: Added ImFontAtlasFlags_NoMouseCursors flag to disable baking software mouse cursors, mostly to save texture memory on very low end hardware. (#1613) +- ImDrawList: Fixed AddRect() with anti-aliasing disabled (lower-right corner pixel was often missing, rounding looks a little better.) (#1646) +- ImDrawList: Added CloneOutput() helper to facilitate the cloning of ImDrawData or ImDrawList for multi-threaded rendering. +- Misc: Functions passed to libc qsort are explicitly marked cdecl to support compiling with vectorcall as the default calling convention. (#1230, #1611) [@RandyGaul] +- Misc: ImVec2: added [] operator. This is becoming desirable for some code working of either axes independently. Better adding it sooner than later. +- Misc: NewFrame(): Added an assert to detect incorrect filling of the io.KeyMap[] array earlier. (#1555) +- Misc: Added IM_OFFSETOF() helper in imgui.h (previously was in imgui_internal.h) +- Misc: Added IM_NEW(), IM_DELETE() helpers in imgui.h (previously were in imgui_internal.h) +- Misc: Added obsolete redirection function GetItemsLineHeightWithSpacing() (which redirects to GetFrameHeightWithSpacing()), as intended and stated in docs of 1.53. +- Misc: Added misc/natvis/imgui.natvis for visual studio debugger users to easily visualize imgui internal types. Added to examples projects. +- Misc: Added IMGUI_USER_CONFIG to define a custom configuration filename. (#255, #1573, #1144, #41) +- Misc: Added IMGUI_STB_TRUETYPE_FILENAME and IMGUI_STB_RECT_PACK_FILENAME compile time directives to use another version of the stb_ files. +- Misc: Updated stb_rect_pack from 0.10 to 0.11 (minor changes). + (Those flags are not used by ImGui itself, they only exists to make it easy for the engine/backend to pass information to the application in a standard manner.) +- Metrics: Added display of Columns state. +- Demo: Improved Selectable() examples. (#1528) +- Demo: Tweaked the Child demos, added a menu bar to the second child to test some navigation functions. +- Demo: Console: Using ImGuiCol_Text to be more friendly to color changes. +- Demo: Using IM_COL32() instead of ImColor() in ImDrawList centric contexts. Trying to phase out use of the ImColor helper whenever possible. +- Examples: Files in examples/ now include their own changelog so it is easier to occasionally update your bindings if needed. +- Examples: Using Dark theme by default. (#707). Tweaked demo code. +- Examples: Added support for horizontal mouse wheel for API that allows it. (#1463) [@tseeker] +- Examples: All examples now setup the io.BackendFlags to signify they can honor mouse cursors, gamepad, etc. +- Examples: DirectX10: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) in every other backends. (#1733) +- Examples: DirectX12: Added DirectX 12 example. (#301) [@jdm3] +- Examples: OpenGL3+GLFW,SDL: Changed GLSL shader version from 330 to 150. (#1466, #1504) +- Examples: OpenGL3+GLFW,SDL: Added a way to override the GLSL version string in the Init function. (#1466, #1504). +- Examples: OpenGL3+GLFW,SDL: Creating VAO in the render function so it can be more easily used by multiple shared OpenGL contexts. (#1217) +- Examples: OpenGL3+GLFW: Using 3.2 context instead of 3.3. (#1466) +- Examples: OpenGL: Setting up glPixelStorei() explicitly before uploading texture. +- Examples: OpenGL: Calls to glPolygonMode() are casting parameters as GLEnum to not fail with more strict bindings. (#1628) [@ilia-glushchenko] +- Examples: Win32 (DirectX9,10,11,12): Added support for mouse cursor shapes. (#1495) +- Examples: Win32 (DirectX9,10,11,12: Support for windows using the CS_DBLCLKS class flag by handling the double-click messages (WM_LBUTTONDBLCLK etc.). (#1538, #754) [@ndandoulakis] +- Examples: Win32 (DirectX9,10,11,12): Made the Win32 proc handlers not assert if there is no active context yet, to be more flexible with creation order. (#1565) +- Examples: GLFW: Added support for mouse cursor shapes (the diagonal resize cursors are unfortunately not supported by GLFW at the moment. (#1495) +- Examples: GLFW: Don't attempt to change the mouse cursor input mode if it is set to GLFW_CURSOR_DISABLED by the application. (#1202) [@PhilCK] +- Examples: SDL: Added support for mouse cursor shapes. (#1626) [@olls] +- Examples: SDL: Using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging (SDL 2.0.4+ only, otherwise using SDL_WINDOW_INPUT_FOCUS instead of previously SDL_WINDOW_MOUSE_FOCUS). (#1559) +- Examples: SDL: Enabled vsync by default so people don't come at us when the examples are running at 2000 FPS and burning a CPU core. +- Examples: SDL: Using SDL_GetPerformanceCounter() / SDL_GetPerformanceFrequency() to handle frame-rate over 1000 FPS properly. (#996) +- Examples: SDL: Using scan-code exclusively instead of a confusing mixture of scan-codes and key-codes. +- Examples: SDL: Visual Studio: Added .vcxproj file. Using %SDL2_DIR% in the default .vcxproj and build files instead of %SDL_DIR%, the earlier being more standard. +- Examples: Vulkan: Visual Studio: Added .vcxproj file. +- Examples: Apple: Fixed filenames in OSX xcode project. Various other Mac friendly fixes. [@gerryhernandez etc.] +- Examples: Visual Studio: Disabled extraneous function-level check in Release build. +- Various fixes, tweaks, internal refactoring, optimizations, comments. + + +----------------------------------------------------------------------- + VERSION 1.53 (Released 2017-12-25) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.53 + +Breaking Changes: + +- Renamed the emblematic `ShowTestWindow()` function to `ShowDemoWindow()`. Kept redirection function (will obsolete). +- Renamed `GetItemsLineHeightWithSpacing()` to `GetFrameHeightWithSpacing()` for consistency. Kept redirection function (will obsolete). +- Renamed `ImGuiTreeNodeFlags_AllowOverlapMode` flag to `ImGuiTreeNodeFlags_AllowItemOverlap`. Kept redirection enum (will obsolete). +- Obsoleted `IsRootWindowFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootWindow)`. Kept redirection function (will obsolete). (#1382) +- Obsoleted `IsRootWindowOrAnyChildFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382) +- Obsoleted `IsRootWindowOrAnyChildHovered()` in favor of using `IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382) +- Obsoleted `SetNextWindowContentWidth() in favor of using `SetNextWindowContentSize()`. Kept redirection function (will obsolete). +- Renamed `ImGuiTextBuffer::append()` helper to `appendf()`, and `appendv()` to `appendfv()` for consistency. If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. +- ImDrawList: Removed 'bool anti_aliased = true' final parameter of `ImDrawList::AddPolyline()` and `ImDrawList::AddConvexPolyFilled()`. Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. +- Style, ImDrawList: Renamed `style.AntiAliasedShapes` to `style.AntiAliasedFill` for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags. +- Style, Begin: Removed `ImGuiWindowFlags_ShowBorders` window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. `style.FrameBorderSize`, `style.WindowBorderSize`, `style.PopupBorderSize`). + Use `ImGui::ShowStyleEditor()` to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. + It is recommended that you use the `StyleColorsClassic()`, `StyleColorsDark()`, `StyleColorsLight()` functions. Also see `ShowStyleSelector()`. +- Style: Removed `ImGuiCol_ComboBg` in favor of combo boxes using `ImGuiCol_PopupBg` for consistency. Combo are normal pop-ups. +- Style: Renamed `ImGuiCol_ChildWindowBg` to `ImGuiCol_ChildBg`. +- Style: Renamed `style.ChildWindowRounding` to `style.ChildRounding`, `ImGuiStyleVar_ChildWindowRounding` to `ImGuiStyleVar_ChildRounding`. +- Removed obsolete redirection functions: SetScrollPosHere() - marked obsolete in v1.42, July 2015. +- Removed obsolete redirection functions: GetWindowFont(), GetWindowFontSize() - marked obsolete in v1.48, March 2016. + +Other Changes: + +- Added `io.OptCursorBlink` option to allow disabling cursor blinking. (#1427) [renamed to io.ConfigCursorBlink in 1.63] +- Added `GetOverlayDrawList()` helper to quickly get access to a ImDrawList that will be rendered in front of every windows. +- Added `GetFrameHeight()` helper which returns `(FontSize + style.FramePadding.y * 2)`. +- Drag and Drop: Added Beta API to easily use drag and drop patterns between imgui widgets. + - Setup a source on a widget with `BeginDragDropSource()`, `SetDragDropPayload()`, `EndDragDropSource()` functions. + - Receive data with `BeginDragDropTarget()`, `AcceptDragDropPayload()`, `EndDragDropTarget()`. + - See ImGuiDragDropFlags for various options. + - The ColorEdit4() and ColorButton() widgets now support Drag and Drop. + - The API is tagged as Beta as it still may be subject to small changes. +- Drag and Drop: When drag and drop is active, tree nodes and collapsing header can be opened by hovering on them for 0.7 seconds. +- Renamed io.OSXBehaviors to io.OptMacOSXBehaviors. Should not affect users as the compile-time default is usually enough. (#473, #650) +- Style: Added StyleColorsDark() style. (#707) [@dougbinks] +- Style: Added StyleColorsLight() style. Best used with frame borders + thicker font than the default font. (#707) +- Style: Added style.PopupRounding setting. (#1112) +- Style: Added style.FrameBorderSize, style.WindowBorderSize, style.PopupBorderSize. Removed ImGuiWindowFlags_ShowBorders window flag! + Borders are now fully set up in the ImGuiStyle structure. Use ImGui::ShowStyleEditor() to look them up. (#707, fix #819, #1031) +- Style: Various small changes to the classic style (most noticeably, buttons are now using blue shades). (#707) +- Style: Renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. +- Style: Renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. +- Style: Removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. (#707) +- Style: Made the ScaleAllSizes() helper rounds down every values so they are aligned on integers. +- Focus: Added SetItemDefaultFocus(), which in the current (master) branch behave the same as doing `if (IsWindowAppearing()) SetScrollHere()`. + In the navigation branch this will also set the default focus. Prefer using this when creating combo boxes with `BeginCombo()` so your code will be forward-compatible with gamepad/keyboard navigation features. (#787) +- Combo: Pop-up grows horizontally to accommodate for contents that is larger then the parent combo button. +- Combo: Added BeginCombo()/EndCombo() API which allows use to submit content of any form and manage your selection state without relying on indices. +- Combo: Added ImGuiComboFlags_PopupAlignLeft flag to BeginCombo() to prioritize keeping the pop-up on the left side (for small-button-looking combos). +- Combo: Added ImGuiComboFlags_HeightSmall, ImGuiComboFlags_HeightLarge, ImGuiComboFlags_HeightLargest to easily provide desired pop-up height. +- Combo: You can use SetNextWindowSizeConstraints() before BeginCombo() to specify specific pop-up width/height constraints. +- Combo: Offset popup position by border size so that a double border isn't so visible. (#707) +- Combo: Recycling windows by using a stack number instead of a unique id, wasting less memory (like menus do). +- InputText: Added ImGuiInputTextFlags_NoUndoRedo flag. (#1506, #1508) [@ibachar] +- Window: Fixed auto-resize allocating too much space for scrollbar when SizeContents is bigger than maximum window size (fixes c0547d3). (#1417) +- Window: Child windows with MenuBar use regular WindowPadding.y so layout look consistent as child or as a regular window. +- Window: Begin(): Fixed appending into a child window with a second Begin() from a different window stack querying the wrong window for the window->Collapsed test. +- Window: Calling IsItemActive(), IsItemHovered() etc. after a call to Begin() provides item data for the title bar, so you can easily test if the title bar is being hovered, etc. (#823) +- Window: Made it possible to use SetNextWindowPos() on a child window. +- Window: Fixed a one frame glitch. When an appearing window claimed the focus themselves, the title bar wouldn't use the focused color for one frame. +- Window: Added ImGuiWindowFlags_ResizeFromAnySide flag to resize from any borders or from the lower-left corner of a window. This requires your backend to honor GetMouseCursor() requests for full usability. (#822) +- Window: Sizing fixes when using SetNextWindowSize() on individual axises. +- Window: Hide new window for one frame until they calculate their size. Also fixes SetNextWindowPos() given a non-zero pivot. (#1694) +- Window: Made mouse wheel scrolling accommodate better to windows that are smaller than the scroll step. +- Window: SetNextWindowContentSize() adjust for the size of decorations (title bar/menu bar), but _not_ for borders are we consistently make borders not affect layout. + If you need a non-child window of an exact size with border enabled but zero window padding, you'll need to accommodate for the border size yourself. +- Window: Using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. (#1380, #1502) +- Window: Active Modal window always set the WantCaptureKeyboard flag. (#744) +- Window: Moving window doesn't use accumulating MouseDelta so straying out of imgui boundaries keeps moved imgui window at the same cursor-relative position. +- IsWindowFocused(): Added ImGuiFocusedFlags_ChildWindows flag to include child windows in the focused test. (#1382). +- IsWindowFocused(): Added ImGuiFocusedFlags_RootWindow flag to start focused test from the root (top-most) window. Obsolete IsRootWindowFocused(). (#1382) +- IsWindowHovered(): Added ImGuiHoveredFlags_ChildWindows flag to include child windows in the hovered test. (#1382). +- IsWindowHovered(): Added ImGuiHoveredFlags_RootWindow flag to start hovered test from the root (top-most) window. The combination of both flags obsoletes IsRootWindowOrAnyChildHovered(). (#1382) +- IsWindowHovered(): Fixed return value when an item is active to use the same logic as IsItemHovered(). (#1382, #1404) +- IsWindowHovered(): Always return true when current window is being moved. (#1382) +- Scrollbar: Fixed issues with vertical scrollbar flickering/appearing, typically when manually resizing and using a pattern of filling available height (e.g. full sized BeginChild). +- Scrollbar: Minor graphical fix for when scrollbar don't have enough visible space to display the full grab. +- Scrolling: Fixed padding and scrolling asymmetry where lower/right sides of a window wouldn't use WindowPadding properly + causing minor scrolling glitches. +- Tree: TreePush with zero arguments was ambiguous. Resolved by making it call TreePush(const void*). [@JasonWilkins] +- Tree: Renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. (#600, #1330) +- MenuBar: Fixed minor rendering issues on the right size when resizing a window very small and using rounded window corners. +- MenuBar: better software clipping to handle small windows, in particular child window don't have minimum constraints so we need to render clipped menus better. +- BeginMenu(): Tweaked the Arrow/Triangle displayed on child menu items. +- Columns: Clipping columns borders on Y axis on CPU because some Linux GPU drivers appears to be unhappy with triangle spanning large regions. (#125) +- Columns: Added ImGuiColumnsFlags_GrowParentContentsSize to internal API to restore old content sizes behavior (may be obsolete). (#1444, #125) +- Columns: Columns width is no longer lost when dragging a column to the right side of the window, until releasing the mouse button you have a chance to save them. (#1499, #125). [@ggtucker] +- Columns: Fixed dragging when using a same of columns multiple times in the frame. (#125) +- Indent(), Unindent(): Allow passing negative values. +- ColorEdit4(): Made IsItemActive() return true when picker pop-up is active. (#1489) +- ColorEdit4(): Tweaked tooltip so that the color button aligns more correctly with text. +- ColorEdit4(): Support drag and drop. Color buttons can be used as drag sources, and ColorEdit widgets as drag targets. (#143) +- ColorPicker4(): Fixed continuously returning true when holding mouse button on the sat/value/alpha locations. We only return true on value change. (#1489) +- NewFrame(): using literal strings in the most-frequently firing IM_ASSERT expressions to increase the odd of programmers seeing them (especially those who don't use a debugger). +- NewFrame() now asserts if neither Render or EndFrame have been called. Exposed EndFrame(). Made it legal to call EndFrame() more than one. (#1423) +- ImGuiStorage: Added BuildSortByKey() helper to rebuild storage from scratch. +- ImFont: Added GetDebugName() helper. +- ImFontAtlas: Added missing Thai punctuation in the GetGlyphRangesThai() ranges. (#1396) [@nProtect] +- ImDrawList: Removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Anti-aliasing is controlled via the regular style.AntiAliased flags. +- ImDrawList: Added ImDrawList::AddImageRounded() helper. (#845) [@thedmd] +- ImDrawList: Refactored to make ImDrawList independent of ImGui. Removed static variable in PathArcToFast() which caused linking issues to some. +- ImDrawList: Exposed ImDrawCornerFlags, replaced occurrences of ~0 with an explicit ImDrawCornerFlags_All. NB: Inversed BotLeft (prev 1<<3, now 1<<2) and BotRight (prev 1<<2, now 1<<3). +- ImVector: Added ImVector::push_front() helper. +- ImVector: Added ImVector::contains() helper. +- ImVector: insert() uses grow_capacity() instead of using grow policy inconsistent with push_back(). +- Internals: Remove requirement to define IMGUI_DEFINE_PLACEMENT_NEW to use the IM_PLACEMENT_NEW macro. (#1103) +- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_NoHoldingActiveID flag from incorrectly setting the ActiveIdClickOffset field. + This had no known effect within imgui code but could have affected custom drag and drop patterns. And it is more correct this way! (#1418) +- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_AllowOverlapMode to avoid temporarily activating widgets on click before they have been correctly double-hovered. (#319, #600) +- Internals: Added SplitterBehavior() helper. (#319) +- Internals: Added IM_NEW(), IM_DELETE() helpers. (#484, #504, #1517) +- Internals: Basic refactor of the settings API which now allows external elements to be loaded/saved. +- Demo: Added ShowFontSelector() showing loaded fonts. +- Demo: Added ShowStyleSelector() to select among default styles. (#707) +- Demo: Renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). +- Demo: Style Editor: Added a "Simplified settings" sections with check-boxes for border size and frame rounding. (#707, #1019) +- Demo: Style Editor: Added combo box to select stock styles and select current font when multiple are loaded. (#707) +- Demo: Style Editor: Using local storage so Save/Revert button makes more sense without code passing its storage. Added horizontal scroll bar. Fixed Save/Revert button to be always accessible. (#1211) +- Demo: Console: Fixed context menu issue. (#1404) +- Demo: Console: Fixed incorrect positioning which was hidden by a minor scroll issue (this would affect people who copied the Console code as is). +- Demo: Constrained Resize: Added more test cases. (#1417) +- Demo: Custom Rendering: Fixed clipping rectangle extruding out of parent window. +- Demo: Layout: Removed unnecessary and misleading BeginChild/EndChild calls. +- Demo: The "Color Picker with Palette" demo supports drag and drop. (#143) +- Demo: Display better mouse cursor info for debugging backends. +- Demo: Stopped using rand() function in demo code. +- Examples: Added a handful of extra comments (about fonts, third-party libraries used in the examples, etc.). +- Examples: DirectX9: Handle loss of D3D9 device (D3DERR_DEVICELOST). (#1464) +- Examples: Added null_example/ which is helpful for quick testing on multiple compilers/settings without relying on graphics library. +- Fix for using alloca() in "Clang with Microsoft Codechain" mode. +- Various fixes, optimizations, comments. + + +----------------------------------------------------------------------- + VERSION 1.52 (2017-10-27) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.52 + +Breaking Changes: + +- IO: `io.MousePos` needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing, instead of ImVec2(-1,-1) as previously) This is needed so we can clear `io.MouseDelta` field when the mouse is made available again. +- Renamed `AlignFirstTextHeightToWidgets()` to `AlignTextToFramePadding()`. Kept inline redirection function (will obsolete). +- Obsoleted the legacy 5 parameters version of Begin(). Please avoid using it. If you need a transparent window background, uses `PushStyleColor()`. The old size parameter there was also misleading and equivalent to calling `SetNextWindowSize(size, ImGuiCond_FirstTimeEver)`. Kept inline redirection function (will obsolete). +- Obsoleted `IsItemHoveredRect()`, `IsMouseHoveringWindow()` in favor of using the newly introduced flags of `IsItemHovered()` and `IsWindowHovered()`. Kept inline redirection function (will obsolete). (#1382) +- Obsoleted 'SetNextWindowPosCenter()' in favor of using 1SetNextWindowPos()` with a pivot value which allows to do the same and more. Keep inline redirection function. +- Removed `IsItemRectHovered()`, `IsWindowRectHovered()` recently introduced in 1.51 which were merely the more consistent/correct names for the above functions which are now obsolete anyway. (#1382) +- Changed `IsWindowHovered()` default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. (#1382) +- Renamed imconfig.h's `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS` to `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS` for consistency. + +Other Changes: + +- ProgressBar: fixed rendering when straddling rounded area. (#1296) +- SliderFloat, DragFloat: Using scientific notation e.g. "%.1e" in the displayed format string doesn't mistakenly trigger rounding of the value. [@MomentsInGraphics] +- Combo, InputFloat, InputInt: Made the small button on the right side align properly with the equivalent colored button of ColorEdit4(). +- IO: Tweaked logic for `io.WantCaptureMouse` so it now outputs false when e.g. hovering over void while an InputText() is active. (#621) [@pdoane] +- IO: Fixed `io.WantTextInput` from mistakenly outputting true when an activated Drag or Slider was previously turned into an InputText(). (#1317) +- Misc: Added flags to `IsItemHovered()`, `IsWindowHovered()` to access advanced hovering-test behavior. Generally useful for pop-ups and drag and drop behaviors: (relates to ~#439, #1013, #143, #925) + - `ImGuiHoveredFlags_AllowWhenBlockedByPopup` + - `ImGuiHoveredFlags_AllowWhenBlockedByActiveItem` + - `ImGuiHoveredFlags_AllowWhenOverlapped` + - `ImGuiHoveredFlags_RectOnly` +- Input: Added `IsMousePosValid()` helper. +- Input: Added `GetKeyPressedAmount()` to easily measure press count when the repeat rate is faster than the frame rate. +- Input/Focus: Disabled TAB and Shift+TAB when CTRL key is held. +- CheckBox: Now rendering a tick mark instead of a full square. +- ColorEdit4: Added "Copy as..." option in context menu. (#346) +- ColorPicker: Improved ColorPicker hue wheel color interpolation. (#1313) [@thevaber] +- ColorButton: Reduced bordering artifact that would be particularly visible with an opaque Col_FrameBg and FrameRounding enabled. +- ColorButton: Fixed rendering color button with a checkerboard if the transparency comes from the global style.Alpha and not from the actual source color. +- TreeNode: Added `ImGuiTreeNodeFlags_FramePadding` flag to conveniently create a tree node with full padding at the beginning of a line, without having to call `AlignTextToFramePadding()`. +- Trees: Fixed calling `SetNextTreeNodeOpen()` on a collapsed window leaking to the first tree node item of the next frame. +- Layout: Horizontal layout is automatically enforced in a menu bar, so you can use non-MenuItem elements without calling SameLine(). +- Separator: Output a vertical separator when used inside a menu bar (or in general when horizontal layout is active, but that isn't exposed yet!). +- Window: Added `IsWindowAppearing()` helper (helpful e.g. as a condition before initializing some of your own things.). +- Window: Added pivot parameter to `SetNextWindowPos()`, making it possible to center or right align a window. Obsoleted `SetNextWindowPosCenter()`. +- Window: Fixed title bar color of top-most window under a modal window. +- Window: Fixed not being able to move a window by clicking on one of its child window. (#1337, #635) +- Window: Fixed `Begin()` auto-fit calculation code that predict the presence of a scrollbar so it works better when window size constraints are used. +- Window: Fixed calling `Begin()` more than once per frame setting `window_just_activated_by_user` which in turn would set enable the Appearing condition for that frame. +- Window: The implicit "Debug" window now uses a "Debug##Default" identifier instead of "Debug" to allow user creating a window called "Debug" without losing their custom flags. +- Window: Made the `ImGuiWindowFlags_NoMove` flag properly inherited from parent to child. In a setup with ParentWindow (no flag) -> Child (NoMove) -> SubChild (no flag), the user won't be able to move the parent window by clicking on SubChild. (#1381) +- Popups: Pop-ups can be closed with a right-click anywhere, without altering focus under the pop-up. (~#439) +- Popups: `BeginPopupContextItem()`, `BeginPopupContextWindow()` are now setup to allow reopening a context menu by right-clicking again. (~#439) +- Popups: `BeginPopupContextItem()` now supports a NULL string identifier and uses the last item ID if available. +- Popups: Added `OpenPopupOnItemClick()` helper which mimic `BeginPopupContextItem()` but doesn't do the BeginPopup(). +- MenuItem: Only activating on mouse release. [@Urmeli0815] (was already fixed in nav branch). +- MenuItem: Made tick mark thicker (thick mark?). +- MenuItem: Tweaks to be usable inside a menu bar (nb: it looks like a regular menu and thus is misleading, prefer using Button() and regular widgets in menu bar if you need to). (#1387) +- ImDrawList: Fixed a rare draw call merging bug which could lead to undisplayed triangles. (#1172, #1368) +- ImDrawList: Fixed a rare bug in `ChannelsMerge()` when all contents has been clipped, leading to an extraneous draw call being created. (#1172, #1368) +- ImFont: Added `AddGlyph()` building helper for use by custom atlas builders. +- ImFontAtlas: Added support for CustomRect API to submit custom rectangles to be packed into the atlas. You can map them as font glyphs, or use them for custom purposes. + After the atlas is built you can query the position of your rectangles in the texture and then copy your data there. You can use this features to create e.g. full color font-mapped icons. +- ImFontAtlas: Fixed fall-back handling when merging fonts, if a glyph was missing from the second font input it could have used a glyph from the first one. (#1349) [@inolen] +- ImFontAtlas: Fixed memory leak on build failure case when stbtt_InitFont failed (generally due to incorrect or supported font type). (#1391) (@Moka42) +- ImFontConfig: Added `RasterizerMultiply` option to alter the brightness of individual fonts at rasterization time, which may help increasing readability for some. +- ImFontConfig: Added `RasterizerFlags` to pass options to custom rasterizer (e.g. the [imgui_freetype](https://github.com/ocornut/imgui_club/tree/master/imgui_freetype) rasterizer in imgui_club has such options). +- ImVector: added resize() variant with initialization value. +- Misc: Changed the internal name formatting of child windows identifier to use slashes (instead of dots) as separator, more readable. +- Misc: Fixed compilation with `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` defined. +- Misc: Marked all format+va_list functions with format attribute so GCC/Clang can warn about misuses. +- Misc: Fixed compilation on NetBSD due to missing alloca.h (#1319) [@RyuKojiro] +- Misc: Improved warnings compilation for newer versions of Clang. (#1324) (@waywardmonkeys) +- Misc: Added `io.WantMoveMouse flags` (from Nav branch) and honored in Examples applications. Currently unused but trying to spread Examples applications code that supports it. +- Misc: Added `IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS` support in imconfig.h to allow user reimplementing the `ImFormatString()` functions e.g. to use stb_printf(). (#1038) +- Misc: [Windows] Fixed default Win32 `SetClipboardText()` handler leaving the Win32 clipboard handler unclosed on failure. [@pdoane] +- Style: Added `ImGuiStyle::ScaleAllSizes(float)` helper to make it easier to have application transition e.g. from low to high DPI with a matching style. +- Metrics: Draw window bounding boxes when hovering Pos/Size; List all draw layers; Trimming empty commands like Render() does. +- Examples: OpenGL3: Save and restore sampler state. (#1145) [@nlguillemot] +- Examples: OpenGL2, OpenGL3: Save and restore polygon mode. (#1307) [@JJscott] +- Examples: DirectX11: Allow creating device with feature level 10 since we don't really need much for that example. (#1333) +- Examples: DirectX9/10/12: Using the Win32 SetCapture/ReleaseCapture API to read mouse coordinates when they are out of bounds. (#1375) [@Gargaj, @ocornut] +- Tools: Fixed binary_to_compressed_c tool to return 0 when successful. (#1350) [@benvanik] +- Internals: Exposed more helpers and unfinished features in imgui_internal.h. (use at your own risk!). +- Internals: A bunch of internal refactoring, hopefully haven't broken anything! Merged a bunch of internal changes from the upcoming Navigation branch. +- Various tweaks, fixes and documentation changes. + +Beta Navigation Branch: +(Lots of work has been done toward merging the Beta Gamepad/Keyboard Navigation branch (#787) in master.) +(Please note that this branch is always kept up to date with master. If you are using the navigation branch, some of the changes include:) +- Nav: Added `#define IMGUI_HAS_NAV` in imgui.h to ease sharing code between both branches. (#787) +- Nav: MainMenuBar now releases focus when user gets out of the menu layer. (#787) +- Nav: When applying focus to a window with only menus, the menu layer is automatically activated. (#787) +- Nav: Added `ImGuiNavInput_KeyMenu` (~Alt key) aside from ImGuiNavInput_PadMenu input as it is one differentiator of pad vs keyboard that was detrimental to the keyboard experience. Although isn't officially supported, it makes the current experience better. (#787) +- Nav: Move requests now wrap vertically inside Menus and Pop-ups. (#787) +- Nav: Allow to collapse tree nodes with NavLeft and open them with NavRight. (#787, #1079). +- Nav: It's now possible to navigate sibling of a menu-bar while navigating inside one of their child. If a Left<>Right navigation request fails to find a match we forward the request to the root menu. (#787, #126) +- Nav: Fixed `SetItemDefaultFocus` from stealing default focus when we are initializing default focus for a menu bar layer. (#787) +- Nav: Support for fall-back horizontal scrolling with PadLeft/PadRight (nb: fall-back scrolling is only used to navigate windows that have no interactive items). (#787) +- Nav: Fixed tool-tip from being selectable in the window selection list. (#787) +- Nav: `CollapsingHeader(bool*)` variant: fixed for `IsItemHovered()` not working properly in the nav branch. (#600, #787) +- Nav: InputText: Fixed using Up/Down history callback feature when Nav is enabled. (#787) +- Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787) +- Nav: More consistently drawing a (thin) navigation rectangle hover filled frames such as tree nodes, collapsing header, menus. (#787) +- Nav: Various internal refactoring. + + +----------------------------------------------------------------------- + VERSION 1.51 (2017-08-24) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.51 + +Breaking Changes: + +Work on dear imgui has been gradually resuming. It means that fixes and new features should be tackled at a faster rate than last year. However, in order to move forward with the library and get rid of some cruft, I have taken the liberty to be a little bit more aggressive than usual with API breaking changes. Read the details below and search for those names in your code! In the grand scheme of things, those changes are small and should not affect everyone, but this is technically our most aggressive release so far in term of API breakage. If you want to be extra forward-facing, you can enable `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h to disable the obsolete names/redirection. + +- Renamed `IsItemHoveredRect()` to `IsItemRectHovered()`. Kept inline redirection function (will obsolete). +- Renamed `IsMouseHoveringWindow()` to `IsWindowRectHovered()` for consistency. Kept inline redirection function (will obsolete). +- Renamed `IsMouseHoveringAnyWindow()` to `IsAnyWindowHovered()` for consistency. Kept inline redirection function (will obsolete). +- Renamed `ImGuiCol_Columns***` enums to `ImGuiCol_Separator***`. Kept redirection enums (will obsolete). +- Renamed `ImGuiSetCond***` types and enums to `ImGuiCond***`. Kept redirection enums (will obsolete). +- Renamed `GetStyleColName()` to `GetStyleColorName()` for consistency. Unlikely to be used by end-user! +- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicitly to fix. +- Marked the weird `IMGUI_ONCE_UPON_A_FRAME` helper macro as obsolete. Prefer using the more explicit `ImGuiOnceUponAFrame`. +- Changed `ColorEdit4(const char* label, float col[4], bool show_alpha = true)` signature to `ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)`, where flags 0x01 is a safe no-op (hello dodgy backward compatibility!). The new `ColorEdit4`/`ColorPicker4` functions have lots of available flags! Check and run the demo window, under "Color/Picker Widgets", to understand the various new options. +- Changed signature of `ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)` to `ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))`. This function was rarely used and was very dodgy (no explicit ID!). +- Changed `BeginPopupContextWindow(bool also_over_items=true, const char* str_id=NULL, int mouse_button=1)` signature to `(const char* str_id=NULL, int mouse_button=1, bool also_over_items=true)`. This is perhaps the most aggressive change in this update, but note that the majority of users relied on default parameters completely, so this will affect only a fraction of users of this already rarely used function. +- Removed `IsPosHoveringAnyWindow()`, which was partly broken and misleading. In the vast majority of cases, people using that function wanted to use `io.WantCaptureMouse` flag. Replaced with IM_ASSERT + comment redirecting user to `io.WantCaptureMouse`. (#1237) +- Removed the old `ValueColor()` helpers, they are equivalent to calling `Text(label)` + `SameLine()` + `ColorButton()`. +- Removed `ColorEditMode()` and `ImGuiColorEditMode` type in favor of `ImGuiColorEditFlags` and parameters to the various Color*() functions. The `SetColorEditOptions()` function allows to initialize default but the user can still change them with right-click context menu. Commenting out your old call to `ColorEditMode()` may just be fine! + +Other Changes: + +- Added flags to `ColorEdit3()`, `ColorEdit4()`. The color edit widget now has a context-menu and access to the color picker. (#346) +- Added flags to `ColorButton()`. (#346) +- Added `ColorPicker3()`, `ColorPicker4()`. The API along with those of the updated `ColorEdit4()` was designed so you may use them in various situation and hopefully compose your own picker if required. There are a bunch of available flags, check the Demo window and comment for `ImGuiColorEditFlags_`. Some of the options it supports are: two color picker types (hue bar + sat/val rectangle, hue wheel + rotating sat/val triangle), display as u8 or float, lifting 0.0..1.0 constraints (currently rgba only), context menus, alpha bar, background checkerboard options, preview tooltip, basic revert. For simple use, calling the existing `ColorEdit4()` function as you did before will be enough, as you can now open the color picker from there. (#346) [@r-lyeh, @nem0, @thennequin, @dariomanesku and @ocornut] +- Added `SetColorEditOptions()` to set default color options (e.g. if you want HSV over RGBA, float over u8, select a default picker mode etc. at startup time without a user intervention. Note that the user can still change options with the context menu unless disabled with `ImGuiColorFlags_NoOptions` or explicitly enforcing a display type/picker mode etc.). +- Added user-facing `IsPopupOpen()` function. (#891) [@mkeeter] +- Added `GetColorU32(u32)` variant that perform the style alpha multiply without a floating-point round trip, and helps makes code more consistent when using ImDrawList APIs. +- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload. +- Added `GetStyleColorVec4(ImGuiCol idx)` which is equivalent to accessing `ImGui::GetStyle().Colors[idx]` (aka return the raw style color without alpha alteration). +- ImFontAtlas: Added `GlyphRangesBuilder` helper class, which makes it easier to build custom glyph ranges from your app/game localization data, or add into existing glyph ranges. +- ImFontAtlas: Added `TexGlyphPadding` option. (#1282) [@jadwallis] +- ImFontAtlas: Made it possible to override size of AddFontDefault() (even if it isn't really recommended!). +- ImDrawList: Added `GetClipRectMin()`, `GetClipRectMax()` helpers. +- Fixed Ini saving crash if the ImGuiWindowFlags_NoSavedSettings gets removed from a window after its creation (unlikely!). (#1000) +- Fixed `PushID()`/`PopID()` from marking parent window as Accessed (which needlessly woke up the root "Debug" window when used outside of a regular window). (#747) +- Fixed an assert when calling `CloseCurrentPopup()` twice in a row. [@nem0] +- Window size can be loaded from .ini data even if ImGuiWindowFlags_NoResize flag is set. (#1048, #1056) +- Columns: Added `SetColumnWidth()`. (#913) [@ggtucker] +- Columns: Dragging a column preserve its width by default. (#913) [@ggtucker] +- Columns: Fixed first column appearing wider than others. (#1266) +- Columns: Fixed allocating space on the right-most side with the assumption of a vertical scrollbar. The space is only allocated when needed. (#125, #913, #893, #1138) +- Columns: Fixed the right-most column from registering its content width to the parent window, which led to various issues when using auto-resizing window or e.g. horizontal scrolling. (#519, #125, #913) +- Columns: Refactored some of the columns code internally toward a better API (not yet exposed) + minor optimizations. (#913) [@ggtucker, @ocornut] +- Popups: Most pop-ups windows can be moved by the user after appearing (if they don't have explicit positions provided by caller, or e.g. sub-menu pop-up). The previous restriction was totally arbitrary. (#1252) +- Tooltip: `SetTooltip()` is expanded immediately into a window, honoring current font / styling setting. Add internal mechanism to override tooltips. (#862) +- PlotHistogram: bars are drawn based on zero-line, so negative values are going under. (#828) +- Scrolling: Fixed return values of `GetScrollMaxX()`, `GetScrollMaxY()` when both scrollbars were enabled. Tweak demo to display more data. (#1271) [@degracode] +- Scrolling: Fixes for Vertical Scrollbar not automatically getting enabled if enabled Horizontal Scrollbar straddle the vertical limit. (#1271, #246) +- Scrolling: `SetScrollHere()`, `SetScrollFromPosY()`: Fixed Y scroll aiming when Horizontal Scrollbar is enabled. (#665). +- [Windows] Clipboard: Fixed not closing Win32 clipboard on early open failure path. (#1264) +- Removed an unnecessary dependency on int64_t which failed on some older compilers. +- Demo: Rearranged everything under Widgets in a more consistent way. +- Demo: Columns: Added Horizontal Scrolling demo. Tweaked another Columns demo. (#519, #125, #913) +- Examples: OpenGL: Various makefiles for MINGW, Linux. (#1209, #1229, #1209) [@fr500, @acda] +- Examples: Enabled vsync by default in example applications, so it doesn't confuse people that the sample run at 2000+ fps and waste an entire CPU. (#1213, #1151). +- Various other small fixes, tweaks, comments, optimizations. + + +----------------------------------------------------------------------- + VERSION 1.50 (2017-06-02) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.50 + +Breaking Changes: + +- Added a void* user_data parameter to Clipboard function handlers. (#875) +- SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal. +- Renamed ImDrawList::PathFill() - rarely used directly - to ImDrawList::PathFillConvex() for clarity and consistency. +- Removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. +- Style: style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. +- BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild(). + +Other Changes: + +- InputText(): Added support for CTRL+Backspace (delete word). +- InputText(): OSX uses Super+Arrows for home/end. Add Shortcut+Backspace support. (#650) [@michaelbartnett] +- InputText(): Got rid of individual OSX-specific options in ImGuiIO, added a single io.OSXBehaviors flag. (#473, #650) +- InputText(): Fixed pressing home key on last character when it isn't a trailing \n (#588, #815) +- InputText(): Fixed state corruption/crash bug in stb_textedit.h redo logic when exhausting undo/redo char buffer. (#715. #681) +- InputTextMultiline(): Fixed CTRL+DownArrow moving scrolling out of bounds. +- InputTextMultiline(): Scrollbar fix for when input and latched internal buffers differs in a way that affects vertical scrollbar existence. (#725) +- ImFormatString(): Fixed an overflow handling bug with implementation of vsnprintf() that do not return -1. (#793) +- BeginChild(const char*) now applies stack id to provided label, consistent with other widgets. (#894, #713) +- SameLine() with explicit X position is relative to left of group/columns. (ref #746, #125, #630) +- SliderInt(), SliderFloat() supports reverse direction (where v_min > v_max). (#854) +- SliderInt(), SliderFloat() better support for when v_min==v_max. (#919) +- SliderInt(), SliderFloat() enforces writing back value when interacting, to be consistent with other widgets. (#919) +- SliderInt, SliderFloat(): Fixed edge case where style.GrabMinSize being bigger than slider width can lead to a division by zero. (#919) +- Added IsRectVisible() variation with explicit start-end positions. (#768) [@thedmd] +- Fixed TextUnformatted() clipping bug in the large-text path when horizontal scroll has been applied. (#692, #246) +- Fixed minor text clipping issue in window title when using font straying above usual line. (#699) +- Fixed SetCursorScreenPos() fixed not adjusting CursorMaxPos as well. +- Fixed scrolling offset when using SetScrollY(), SetScrollFromPosY(), SetScrollHere() with menu bar. +- Fixed using IsItemActive() after EndGroup() or any widget using groups. (#840, #479) +- Fixed IsItemActive() lagging by one frame on initial widget activation. (#840) +- Fixed Separator() zero-height bounding box resulting in clipping when laying exactly on top line of clipping rectangle (#860) +- Fixed PlotLines() PlotHistogram() calling with values_count == 0. +- Fixed clicking on a window's void while staying still overzealously marking .ini settings as dirty. (#923) +- Fixed assert triggering when a window has zero rendering but has a callback. (#810) +- Scrollbar: Fixed rendering when sizes are negative to reduce glitches (which can happen with certain style settings and zero WindowMinSize). +- EndGroup(): Made IsItemHovered() work when an item was activated within the group. (#849) +- BulletText(): Fixed stopping to display formatted string after the '##' mark. +- Closing the focused window restore focus to the first active root window in descending z-order .(part of #727) +- Word-wrapping: Fixed a bug where we never wrapped after a 1 character word. [@sronsse] +- Word-wrapping: Fixed TextWrapped() overriding wrap position if one is already set. (#690) +- Word-wrapping: Fixed incorrect testing for negative wrap coordinates, they are perfectly legal. (#706) +- ImGuiListClipper: Fixed automatic-height calc path dumbly having user display element 0 twice. (#661, #716) +- ImGuiListClipper: Fix to behave within column. (#661, #662, #716) +- ImDrawList: Renamed ImDrawList::PathFill() to ImDrawList::PathFillConvex() for clarity. (BREAKING API) +- Columns: End() avoid calling Columns(1) if no columns set is open, not sure why it wasn't the case already (pros: faster, cons: exercise less code). +- ColorButton(): Fix ColorButton showing wrong hex value for alpha. (#1068) [@codecat] +- ColorEdit4(): better preserve inputting value out of 0..255 range, display then clamped in Hexadecimal form. +- Shutdown() clear out some remaining pointers for sanity. (#836) +- Added IMGUI_USE_BGRA_PACKED_COLOR option in imconfig.h (#767, #844) [@thedmd] +- Style: Removed the inconsistent shadow under RenderCollapseTriangle() (~#707) +- Style: Added ButtonTextAlign, ImGuiStyleVar_ButtonTextAlign. (#842) +- ImFont: Allowing to use up to 0xFFFE glyphs in same font (increased from previous 0x8000). +- ImFont: Added GetGlyphRangesThai() helper. [@nProtect] +- ImFont: CalcWordWrapPositionA() fixed font scaling with fallback character. +- ImFont: Calculate and store the approximate texture surface to get an idea of how costly each source font is. +- ImFontConfig: Added GlyphOffset to explicitly offset glyphs at font build time, useful for merged fonts. Removed MergeGlyphCenterV. (BREAKING API) +- Clarified asserts in CheckStacksSize() when there is a stack mismatch. +- Context: Support for #define-ing GImGui and IMGUI_SET_CURRENT_CONTEXT_FUNC to enable custom thread-based hackery (#586) +- Updated stb_truetype.h to 1.14 (added OTF support, removed warnings). (#883, #976) +- Updated stb_rect_pack.h to 0.10 (removed warnings). (#883) +- Added ImGuiMouseCursor_None enum value for convenient usage by app/binding. +- Clipboard: Added a void* user_data parameter to Clipboard function handlers. (#875) (BREAKING API) +- Internals: Refactor internal text alignment options to use ImVec2, removed ImGuiAlign. (#842, #222) +- Internals: Renamed ImLoadFileToMemory to ImFileLoadToMemory to be consistent with ImFileOpen + fix mismatching .h name. (#917) +- OS/Windows: Fixed Windows default clipboard handler leaving its buffer unfreed on application's exit. (#714) +- OS/Windows: No default IME handler when compiling for Windows using GCC. (#738) +- OS/Windows: Now using _wfopen() instead of fopen() to allow passing in paths/filenames with UTF-8 characters. (#917) +- Tools: binary_to_compressed_c: Avoid ?? trigraphs sequences in string outputs which break some older compilers. (#839) +- Demo: Added an extra 3-way columns demo. +- Demo: ShowStyleEditor: show font character map / grid in more details. +- Demo: Console: Fixed a completion bug when multiple candidates are equals and match until the end. +- Demo: Fixed 1-byte off overflow in the ShowStyleEditor() combo usage. (#783) [@bear24rw] +- Examples: Accessing ImVector fields directly, feel less stl-ey. (#810) +- Examples: OpenGL*: Saving/restoring existing scissor rectangle for completeness.

Now using `CreateContext()`, `DestroyContext()`, `GetCurrentContext()`, `SetCurrentContext()`. If you were using multiple contexts the change should be obvious and trivial. +- Obsoleted old signature of `CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false)`, as extra parameters were badly designed and rarely used. Most uses were using 1 parameter and shouldn't affect you. You can replace the "default_open = true" flag in new API with `CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen)`. +- Changed `ImDrawList::PushClipRect(ImVec4 rect)` to `ImDraw::PushClipRect(ImVec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false)`. Note that higher-level `ImGui::PushClipRect()` is preferable because it will clip at logic/widget level, whereas `ImDrawList::PushClipRect()` only affect your renderer. +- Title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore (see #655). If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color. (Or If this is confusing, just pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive.

(#581, #324) +- Added CreateContext()/DestroyContext()/GetCurrentContext()/SetCurrentContext(). Obsoleted nearly identical GetInternalState()/SetInternalState() functions. (#586, #269) +- Added NewLine() to undo a SameLine() and as a shy reminder that horizontal layout support hasn't been implemented yet. +- Added IsItemClicked() helper. (#581) +- Added CollapsingHeader() variant with close button. (#600) +- Fixed MenuBar missing lower border when borders are enabled. +- InputText(): Fixed clipping of cursor rendering in case it gets out of the box (which can be forced w/ ImGuiInputTextFlags_NoHorizontalScroll. (#601) +- Style: Changed default IndentSpacing from 22 to 21. (#581, #324) +- Style: Fixed TitleBg/TitleBgActive color being rendered above WindowBg color, which was inconsistent and causing visual artifact. (#655) + This broke the meaning of TitleBg and TitleBgActive. Only affect values where Alpha<1.0f. Fixed default theme. Read comments in "API BREAKING CHANGES" section to convert. +- Relative rendering of order of Child windows creation is preserved, to allow more control with overlapping children. (#595) +- Fixed GetWindowContentRegionMax() being off by ScrollbarSize amount when explicit SizeContents is set. +- Indent(), Unindent(): optional non-default indenting width. (#324, #581) +- Bullet(), BulletText(): Slightly bigger. Less polygons. +- ButtonBehavior(): fixed subtle old bug when a repeating button would also return true on mouse release (barely noticeable unless RepeatRate is set to be very slow). (#656) +- BeginMenu(): a menu that becomes disabled while open gets closed down, facilitate user's code. (#126) +- BeginGroup(): fixed using within Columns set. (#630) +- Fixed a lag in reading the currently hovered window when dragging a window. (#635) +- Obsoleted 4 parameters version of CollapsingHeader(). Refactored code into TreeNodeBehavior. (#600, #579) +- Scrollbar: minor fix for top-right rounding of scrollbar background when window has menu bar but no title bar. +- MenuItem(): the check mark renders in disabled color when menu item is disabled. +- Fixed clipping rectangle floating point representation to ensure renderer-side float point operations yield correct results in typical DirectX/GL settings. (#582, 597) +- Fixed GetFrontMostModalRootWindow(), fixing missing fade-out when a combo pop was used stacked over a modal window. (#604) +- ImDrawList: Added AddQuad(), AddQuadFilled() helpers. +- ImDrawList: AddText() refactor, moving some code to ImFont, reserving less unused vertices when large vertical clipping occurs. +- ImFont: Added RenderChar() helper. +- ImFont: Added AddRemapChar() helper.

Some hand-tuned layout may be affected slightly. (#346) +- Style: removed `style.WindowFillAlphaDefault` which was confusing and redundant, baked alpha into `ImGuiCol_WindowBg` color. If you had a custom WindowBg color but didn't change WindowFillAlphaDefault, multiply WindowBg alpha component by 0.7. Renamed `ImGuiCol_TooltipBg` to `ImGuiCol_PopupBG`, applies to other types of pop-ups. `bg_alpha` parameter of 5-parameters version of Begin() is an override. (#337) +- InputText(): Added BufTextLen field in ImGuiTextEditCallbackData. Requesting user to update it if the buffer is modified in the callback. Added a temporary length-check assert to minimize panic for the 3 people using the callback. (#541) +- Renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). (#340) + +Other Changes: + +- Consistently honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. Some hand-tuned layout may be affected slightly. (#346) +- Fixed clipping of child windows within parent not taking account of child outer clipping boundaries (including scrollbar, etc.). (#506) +- TextUnformatted(): Fixed rare crash bug with large blurb of text (2k+) not finished with a '\n' and fully above the clipping Y line. (#535) +- IO: Added 'KeySuper' field to hold CMD keyboard modifiers for OS X. Updated all examples accordingly.

(#346) +- Added GetFontTexUvWhitePixel() helper, convenient for direct use of ImDrawList api. +- Selectable(): Added ImGuiSelectableFlags_AllowDoubleClick flag to allow user reacting on double-click. (@zapolnov) (#516) +- Begin(): made the close button explicitly set the boolean to false instead of toggling it. (#499) +- BeginChild()/EndChild(): fixed incorrect layout to allow widgets submitted after an auto-fitted child window.

(#462, #503) +- Fixed Image(), ImageButtion() rendering a rectangle 1 px too large on each axis. (#457) +- SetItemAllowOverlap(): Promoted from imgui_internal.h to public imgui.h api. (#517) +- Combo(): Right-most button stays highlighted when pop-up is open. +- Combo(): Display pop-up above if there's isn't enough space below / or select largest side. (#505) +- DragFloat(), SliderFloat(), InputFloat(): fixed cases of erroneously returning true repeatedly after a text input modification (e.g. "0.0" --> "0.000" would keep returning true). (#564) +- DragFloat(): Always apply value when mouse is held/widget active, so that an always-reseting variable (e.g. non saved local) can be passed. +- InputText(): OS X friendly behaviors: Word movement uses ALT key; Shortcuts uses CMD key; Double-clicking text select a single word; Jumping to next word sets cursor to end of current word instead of beginning of current word. (@zhiayang), (#473) +- InputText(): Added BufTextLen in ImGuiTextEditCallbackData. Requesting user to maintain it if buffer is modified. Zero-ing structure properly before use. (#541) +- CheckboxFlags(): Added support for testing/setting multiple flags at the same time. (@DMartinek) (#555) +- TreeNode(), CollapsingHeader() fixed not being able to use "##" sequence in a formatted label. +- ColorEdit4(): Empty label doesn't add InnerSpacing.x, matching behavior of other widgets. (#346) +- ColorEdit4(): Removed unnecessary calls to scanf() when idle in hexadecimal edit mode. +- BeginPopupContextItem(), BeginPopupContextWindow(): added early out optimization. +- CaptureKeyboardFromApp() / CaptureMouseFromApp(): added argument to allow clearing the capture flag. (#533) +- ImDrawList: Fixed index-overflow check broken by AddText() casting current index back to ImDrawIdx. (#514) +- ImDrawList: Fixed incorrect removal of trailing draw command if it is a callback command. +- ImDrawList: Allow windows with only a callback only to be functional. (#524) +- ImDrawList: Fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. (#457) +- ImDrawList: Fixed ImDrawList::AddCircle() to fit precisely within bounding box like AddCircleFilled() and AddRectFilled(). (#457) +- ImDrawList: AddCircle(), AddRect() takes optional thickness parameter. +- ImDrawList: Added AddTriangle(). +- ImDrawList: Added PrimQuadUV() helper to ease custom rendering of textured quads (require primitive reserve). +- ImDrawList: Allow AddText(ImFont\* font, float font_size, ...) variant to take NULL/0.0f as default. +- ImFontAtlas: heuristic increase default texture width up for large number of glyphs.

It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies). + +Dear ImGui is designed to enable fast iterations and to empower programmers to create content creation tools and visualization / debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries. + +Dear ImGui is particularly suited to integration in games engine (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard. + +See [Software using dear imgui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui), [Quotes](https://github.com/ocornut/imgui/wiki/Quotes) and [Gallery](https://github.com/ocornut/imgui/issues/1902) pages to get an idea of its use cases. + +Dear ImGui is self-contained within a few files that you can easily copy and compile into your application/engine: +- imgui.cpp +- imgui.h +- imgui_demo.cpp +- imgui_draw.cpp +- imgui_widgets.cpp +- imgui_internal.h +- imconfig.h (empty by default, user-editable) +- imstb_rectpack.h +- imstb_textedit.h +- imstb_truetype.h + +No specific build process is required.

![sample code output](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v160/code_sample_03_color.gif) + +### How it works + +Check out the References section if you want to understand the core principles behind the IMGUI paradigm. An IMGUI tries to minimize superfluous state duplication, state synchronization and state retention from the user's point of view. It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces. + +Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase. + +_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._ + +Dear ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc. + +Demo Binaries +------------- + +You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here: +- [imgui-demo-binaries-20181008.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20181008.zip) (Windows binaries, Dear ImGui 1.66 WIP built 2018/10/08, master branch, 5 executables) + +The demo applications are unfortunately not yet DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your Style with `style.ScaleAllSizes()`. + +Bindings +-------- + +Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you about an hour to integrate Dear ImGui in your custom engine. Make sure to spend time reading the FAQ, the comments and other documentation! + +_NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_ + +Languages: (third-party bindings) +- C: [cimgui](https://github.com/cimgui/cimgui) (2018: now auto-generated! you can use its json output to generate bindings for other languages) +- C#/.Net: [ImGui.NET](https://github.com/mellinoe/ImGui.NET) +- ChaiScript: [imgui-chaiscript](https://github.com/JuJuBoSc/imgui-chaiscript) +- D: [DerelictImgui](https://github.com/Extrawurst/DerelictImgui) +- Go: [imgui-go](https://github.com/inkyblackness/imgui-go) or [go-imgui](https://github.com/Armored-Dragon/go-imgui) +- Haxe/hxcpp: [linc_imgui](https://github.com/Aidan63/linc_imgui) +- Java: [jimgui](https://github.com/ice1000/jimgui) +- JavaScript: [imgui-js](https://github.com/flyover/imgui-js) +- Lua: [LuaJIT-ImGui](https://github.com/sonoro1234/LuaJIT-ImGui), [imgui_lua_bindings](https://github.com/patrickriordan/imgui_lua_bindings) or [lua-ffi-bindings](https://github.com/thenumbernine/lua-ffi-bindings) +- Odin: [odin-dear_imgui](https://github.com/ThisDrunkDane/odin-dear_imgui) +- Pascal: [imgui-pas](https://github.com/dpethes/imgui-pas) +- PureBasic: [pb-cimgui](https://github.com/hippyau/pb-cimgui) +- Python [CyImGui](https://github.com/chromy/cyimgui) or [pyimgui](https://github.com/swistakm/pyimgui) +- Rust: [imgui-rs](https://github.com/Gekkio/imgui-rs) +- Swift [swift-imgui](https://github.com/mnmly/Swift-imgui) + +Frameworks: +- Renderers: DirectX 9/10/11/12, Metal, OpenGL2, OpenGL3+/ES2/ES3, Vulkan: [examples/](https://github.com/ocornut/imgui/tree/master/examples) +- Platform: GLFW, SDL, Win32, OSX, Freeglut: [examples/](https://github.com/ocornut/imgui/tree/master/examples) +- Framework: Allegro 5, Marmalade: [examples/](https://github.com/ocornut/imgui/tree/master/examples) +- Unmerged PR: SDL2 + OpenGLES + Emscripten: [#336](https://github.com/ocornut/imgui/pull/336) +- Unmerged PR: Android: [#421](https://github.com/ocornut/imgui/pull/421) +- Cinder: [Cinder-ImGui](https://github.com/simongeilfus/Cinder-ImGui) +- Cocos2d-x: [imguix](https://github.com/c0i/imguix), [#551](https://github.com/ocornut/imgui/issues/551) +- Flexium: [FlexGUI](https://github.com/DXsmiley/FlexGUI) +- GML/GameMakerStudio2: [ImGuiGML](https://marketplace.yoyogames.com/assets/6221/imguigml) +- Irrlicht: [IrrIMGUI](https://github.com/ZahlGraf/IrrIMGUI) +- Ogre: [ogreimgui](https://bitbucket.org/LMCrashy/ogreimgui/src) +- OpenFrameworks: [ofxImGui](https://github.com/jvcleave/ofxImGui) +- OpenSceneGraph/OSG: [gist](https://gist.github.com/fulezi/d2442ca7626bf270226014501357042c) +- ORX: [pr #1843](https://github.com/ocornut/imgui/pull/1843) +- LÖVE+Lua: [love-imgui](https://github.com/slages/love-imgui) +- Magnum: [magnum-imgui](https://github.com/lecopivo/magnum-imgui), [MagnumImguiPort](https://github.com/lecopivo/MagnumImguiPort) +- NanoRT: [syoyo/imgui](https://github.com/syoyo/imgui/tree/nanort) +- Qt3d: [imgui-qt3d](https://github.com/alpqr/imgui-qt3d), QOpenGLWindow [qtimgui](https://github.com/ocornut/imgui/issues/1910) +- SFML: [imgui-sfml](https://github.com/EliasD/imgui-sfml) +- Software renderer: [imgui_software_renderer](https://github.com/emilk/imgui_software_renderer) +- Unreal Engine 4: [segross/UnrealImGui](https://github.com/segross/UnrealImGui) or [sronsse/UnrealEngine_ImGui](https://github.com/sronsse/UnrealEngine_ImGui) + +For other bindings: see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings/).

This is mainly because "Retained Mode" GUIs have been so widespread and predominant. The following links can give you a better understanding about how Immediate Mode GUIs works. +- [Johannes 'johno' Norneby's article](http://www.johno.se/book/imgui.html). +- [A presentation by Rickard Gustafsson and Johannes Algelind](http://www.cse.chalmers.se/edu/year/2011/course/TDA361/Advanced%20Computer%20Graphics/IMGUI.pdf). +- [Jari Komppa's tutorial on building an ImGui library](http://iki.fi/sol/imgui/). +- [Casey Muratori's original video that popularized the concept](https://mollyrocket.com/861). +- [Nicolas Guillemot's CppCon'16 flash-talk about Dear ImGui](https://www.youtube.com/watch?v=LSRJ1jZq90k). +- [Thierry Excoffier's Zero Memory Widget](http://perso.univ-lyon1.fr/thierry.excoffier/ZMW/). + +See the [Wiki](https://github.com/ocornut/imgui/wiki) for more references and [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for third-party bindings to different languages and frameworks. + +Support Forums +-------------- + +If you have issues with: compiling, linking, adding fonts, running or displaying Dear ImGui, or wiring inputs: please post on the Discourse forum: https://discourse.dearimgui.org. + +For any other questions, bug reports, requests, feedback, you may post on https://github.com/ocornut/imgui/issues. Please read and fill the New Issue template carefully. + +Frequently Asked Question (FAQ) +------------------------------- + +**Where is the documentation?** + +- The documentation is at the top of imgui.cpp + effectively imgui.h. +- Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. +- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder. +- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort. +- Your programming IDE is your friend, find the type or function declaration to find comments associated to it. + +**Which version should I get?** + +I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported. + +You may also peak at the [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) branches. Even though they are marked beta, several projects are using them and they are kept in sync with master regularly. + +**Who uses Dear ImGui?** + +See the [Quotes](https://github.com/ocornut/imgui/wiki/Quotes) and [Software using dear imgui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) pages for an (incomplete) list of games/software which are publicly known to use dear imgui. Please add yours if you can! + +**Why the odd dual naming, "dear imgui" vs "ImGui"?** + +The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations. + +**How can I tell whether to dispatch mouse/keyboard to imgui or to my application?** +
**How can I display an image? What is ImTextureID, how does it works?** +
**How can I have multiple widgets with the same label or without a label? A primer on labels and the ID Stack.** +
**How can I use my own math types instead of ImVec2/ImVec4?** +
**How can I load a different font than the default?** +
**How can I easily use icons in my application?** +
**How can I load multiple fonts?** +
**How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic?** +
**How can I use the drawing facilities without an Dear ImGui window? (using ImDrawList API)** +
**I integrated Dear ImGui in my engine and the text or lines are blurry..** +
**I integrated Dear ImGui in my engine and some elements are disappearing when I move windows around..** +
**How can I help?** + +See the FAQ in imgui.cpp for answers. + +**How do you use Dear ImGui on a platform that may not have a mouse or keyboard?** + +You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`). + +You can share your computer mouse seamlessly with your console/tablet/phone using [Synergy](http://synergy-project.org). This is the preferred solution for developer productivity. In particular, their [micro-synergy-client](https://github.com/symless/micro-synergy-client) repo there is _uSynergy.c_ sources for a small embeddable that you can use on any platform to connect to your host PC using Synergy 1.x. You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui). + +For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing for screen real-estate and precision. + +**Can you create elaborate/serious tools with Dear ImGui?** + +Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library. + +Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful. + +**Can you reskin the look of Dear ImGui?** + +You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimized to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged): + +![LumixEngine](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v151/lumix-201710-rearranged.png) + +**Why using C++ (as opposed to C)?** + +Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience. + +There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. This is designed for binding other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for third-party bindings to other languages. + +Support dear imgui +------------------ + +**How can I help financing further development of Dear ImGui?** + +Your contributions are keeping the library alive.

Although it is tempting to rewrite both of the + imgui_impl_xxxx files to fit under your coding style, consider that it is not necessary! + In fact, if you are new to Dear ImGui, rewriting them will almost always be harder. + + Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering + system layered over DirectX11. + Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first. + Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer + using your own functions, etc. + Please consider using the bindings to the lower-level platform/graphics API as-is. + + Example: your engine is multi-platform (consoles, phones, etc.), you have high-level systems everywhere. + Suggestion: step 1: try using a non-portable binding first (e.g. win32 + underlying graphics API)! + This is counter-intuitive, but this will get you running faster! Once you better understand how imgui + works and is bound, you can rewrite the code using your own systems. + + - From Dear ImGui 1.XX we added an (optional) feature called "viewport" which allows imgui windows to be + seamlessly detached from the main application window. This is achieved using an extra layer to the + platform and renderer bindings, which allows imgui to communicate platform-specific requests such as + "create an additional OS window", "create a render context", "get the OS position of this window" etc. + When using this feature, the coupling with your OS/renderer becomes much tighter than a regular imgui + integration. It is also much more complicated and require more work to integrate correctly. + If you are new to imgui and you are trying to integrate it into your application, first try to ignore + everything related to Viewport and Platform Windows. You'll be able to come back to it later! + Note that if you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit + from improvements and fixes related to viewports and platform windows without extra work on your side. + See 'ImGuiPlatformIO' for details. + + +List of Platforms Bindings in this repository: + + imgui_impl_glfw.cpp ; GLFW (Windows, macOS, Linux, etc.) http://www.glfw.org/ + imgui_impl_osx.mm ; macOS native API + imgui_impl_sdl.cpp ; SDL2 (Windows, macOS, Linux, iOS, Android) https://www.libsdl.org + imgui_impl_win32.cpp ; Win32 native API (Windows) + imgui_impl_freeglut.cpp ; FreeGLUT (if you really miss the 90's) + +List of Renderer Bindings in this repository: + + imgui_impl_dx9.cpp ; DirectX9 + imgui_impl_dx10.cpp ; DirectX10 + imgui_impl_dx11.cpp ; DirectX11 + imgui_impl_dx12.cpp ; DirectX12 + imgui_impl_metal.mm ; Metal (with ObjC) + imgui_impl_opengl2.cpp ; OpenGL2 (legacy, fixed pipeline <- don't use with modern OpenGL context) + imgui_impl_opengl3.cpp ; OpenGL3, OpenGL ES 2, OpenGL ES 3 (modern programmable pipeline) + imgui_impl_vulkan.cpp ; Vulkan + +List of high-level Frameworks Bindings in this repository: (combine Platform + Renderer) + + imgui_impl_allegro5.cpp + imgui_impl_marmalade.cpp + +Third-party framework, graphics API and languages bindings are listed at: + + https://github.com/ocornut/imgui/wiki/Bindings + + Languages: C, C#, ChaiScript, D, Go, Haxe, Java, Lua, Odin, Pascal, PureBasic, Python, Rust, Swift... + Frameworks: Cinder, Cocoa (OSX), Cocos2d-x, Emscripten, SFML, GML/GameMaker Studio, Irrlicht, Ogre, + OpenSceneGraph, openFrameworks, LOVE, NanoRT, Nim Game Lib, Qt3d, SFML, Unreal Engine 4... + Miscellaneous: Software Renderer, RemoteImgui, etc. + + +--------------------------------------- + EXAMPLE APPLICATIONS +--------------------------------------- + +Building: + Unfortunately in 2018 it is still tedious to create and maintain portable build files using external + libraries (the kind we're using here to create a window and render 3D triangles) without relying on + third party software.

GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE - - Add the Dear ImGui source files to your projects, using your preferred build system. - It is recommended you build the .cpp files as part of your project and not as a library. - - You can later customize the imconfig.h file to tweak some compilation time behavior, such as integrating imgui types with your own maths types. - - See examples/ folder for standalone sample applications. - - You may be able to grab and copy a ready made imgui_impl_*** file from the examples/. + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - Add the Dear ImGui source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and not as shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating imgui types with your own maths types. - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering informatioe are stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. - - Init: retrieve the ImGuiIO structure with ImGui::GetIO() and fill the fields marked 'Settings': at minimum you need to set io.DisplaySize - (application resolution). Later on you will fill your keyboard mapping, clipboard handlers, and other advanced features but for a basic - integration you don't need to worry about it all. - - Init: call io.Fonts->GetTexDataAsRGBA32(...), it will build the font atlas texture, then load the texture pixels into graphics memory. - - Every frame: - - In your main loop as early a possible, fill the IO fields marked 'Input' (e.g. mouse position, buttons, keyboard info, etc.) - - Call ImGui::NewFrame() to begin the frame - - You can use any ImGui function you want between NewFrame() and Render() - - Call ImGui::Render() as late as you can to end the frame and finalize render data. it will call your io.RenderDrawListFn handler. - (Even if you don't render, call Render() and ignore the callback, or call EndFrame() instead. Otherwhise some features will break) - - All rendering information are stored into command-lists until ImGui::Render() is called. - - Dear ImGui never touches or knows about your GPU state. the only function that knows about GPU is the RenderDrawListFn handler that you provide. - - Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" phases - of your own application. - - Refer to the examples applications in the examples/ folder for instruction on how to setup your code. - - A minimal application skeleton may be: + HOW A SIMPLE APPLICATION MAY LOOK LIKE + EXHIBIT 1: USING THE EXAMPLE BINDINGS (imgui_impl_XXX.cpp files from the examples/ folder) - // Application init + // Application init: create a dear imgui context, setup some options, load fonts ImGui::CreateContext(); ImGuiIO& io = ImGui::GetIO(); - io.DisplaySize.x = 1920.0f; - io.DisplaySize.y = 1280.0f; - io.RenderDrawListsFn = MyRenderFunction; // Setup a render function, or set to NULL and call GetDrawData() after Render() to access render data. - // TODO: Fill others settings of the io structure later. + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. - // Load texture atlas (there is a default font so you don't need to care about choosing a font yet) - unsigned char* pixels; + // Initialize helper Platform and Renderer bindings (here we are using imgui_impl_win32 and imgui_impl_dx11) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into screen + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + EXHIBIT 2: IMPLEMENTING CUSTOM BINDING / CUSTOM ENGINE + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Build and load the texture atlas into a texture + // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) int width, height; - io.Fonts->GetTexDataAsRGBA32(pixels, &width, &height); - // TODO: At this points you've got the texture data and you need to upload that your your graphic system: - MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA) - // TODO: Store your texture pointer/identifier (whatever your engine uses) in 'io.Fonts->TexID'.

You might want to track which key-downs + were targeted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.) Q: How can I display an image? What is ImTextureID, how does it works? - A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function. - Dear ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry! - It could be an identifier to your OpenGL texture (cast GLuint to void*), a pointer to your custom engine material (cast MyMaterial* to void*), etc. - At the end of the chain, your renderer takes this void* to cast it back into whatever it needs to select a current texture to render. - Refer to examples applications, where each renderer (in a imgui_impl_xxxx.cpp file) is treating ImTextureID as a different thing. - (c++ tip: OpenGL uses integers to identify textures. You can safely store an integer into a void*, just cast it to void*, don't take it's address!) - To display a custom image/texture within an ImGui window, you may use ImGui::Image(), ImGui::ImageButton(), ImDrawList::AddImage() functions. - Dear ImGui will generate the geometry and draw calls using the ImTextureID that you passed and which your renderer can use. - You may call ImGui::ShowMetricsWindow() to explore active draw lists and visualize/understand how the draw data is generated. - It is your responsibility to get textures uploaded to your GPU. + A: Short explanation: + - You may use functions such as ImGui::Image(), ImGui::ImageButton() or lower-level ImDrawList::AddImage() to emit draw calls that will use your own textures. + - Actual textures are identified in a way that is up to the user/engine. Those identifiers are stored and passed as ImTextureID (void*) value. + - Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason). + Please read documentations or tutorials on your graphics API to understand how to display textures on the screen before moving onward. - Q: Can I have multiple widgets with the same label? Can I have widget without a label? - A: Yes. A primer on labels and the ID stack... + Long explanation: + - Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. + At the end of the frame those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code + to render them is generally fairly short (a few dozen lines). In the examples/ folder we provide functions for popular graphics API (OpenGL, DirectX, etc.). + - Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API. + We carry the information to identify a "texture" in the ImTextureID type. + ImTextureID is nothing more that a void*, aka 4/8 bytes worth of data: just enough to store 1 pointer or 1 integer of your choice. + Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely pass ImTextureID values until they reach your rendering function. + - In the examples/ bindings, for each graphics API binding we decided on a type that is likely to be a good representation for specifying + an image from the end-user perspective. This is what the _examples_ rendering functions are using: - - Elements that are typically not clickable, such as Text() items don't need an ID. + OpenGL: ImTextureID = GLuint (see ImGui_ImplGlfwGL3_RenderDrawData() function in imgui_impl_glfw_gl3.cpp) + DirectX9: ImTextureID = LPDIRECT3DTEXTURE9 (see ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp) + DirectX11: ImTextureID = ID3D11ShaderResourceView* (see ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp) + DirectX12: ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE (see ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp) - - Interactive widgets require state to be carried over multiple frames (most typically Dear ImGui often needs to remember what is - the "active" widget). to do so they need a unique ID. unique ID are typically derived from a string label, an integer index or a pointer. + For example, in the OpenGL example binding we store raw OpenGL texture identifier (GLuint) inside ImTextureID. + Whereas in the DirectX11 example binding we store a pointer to ID3D11ShaderResourceView inside ImTextureID, which is a higher-level structure + tying together both the texture and information about its format and how to read it. + - If you have a custom engine built over e.g. OpenGL, instead of passing GLuint around you may decide to use a high-level data type to carry information about + the texture as well as how to display it (shaders, etc.). The decision of what to use as ImTextureID can always be made better knowing how your codebase + is designed. If your engine has high-level data types for "textures" and "material" then you may want to use them. + If you are starting with OpenGL or DirectX or Vulkan and haven't built much of a rendering engine over them, keeping the default ImTextureID + representation suggested by the example bindings is probably the best choice. + (Advanced users may also decide to keep a low-level type in ImTextureID, and use ImDrawList callback and pass information to their renderer) - Button("OK"); // Label = "OK", ID = hash of "OK" - Button("Cancel"); // Label = "Cancel", ID = hash of "Cancel" + User code may do: - - ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" - in two different windows or in two different locations of a tree. + // Cast our texture type to ImTextureID / void* + MyTexture* texture = g_CoffeeTableTexture; + ImGui::Image((void*)texture, ImVec2(texture->Width, texture->Height)); + + The renderer function called after ImGui::Render() will receive that same value that the user code passed: + + // Cast ImTextureID / void* stored in the draw command as our texture type + MyTexture* texture = (MyTexture*)pcmd->TextureId; + MyEngineBindTexture2D(texture); + + Once you understand this design you will understand that loading image files and turning them into displayable textures is not within the scope of Dear ImGui. + This is by design and is actually a good thing, because it means your code has full control over your data types and how you display them. + If you want to display an image file (e.g. PNG file) into the screen, please refer to documentation and tutorials for the graphics API you are using. + + Here's a simplified OpenGL example using stb_image.h: + + // Use stb_image.h to load a PNG from disk and turn it into raw RGBA pixel data: + #define STB_IMAGE_IMPLEMENTATION + #include + [...] + int my_image_width, my_image_height; + unsigned char* my_image_data = stbi_load("my_image.png", &my_image_width, &my_image_height, NULL, 4); + + // Turn the RGBA pixel data into an OpenGL texture: + GLuint my_opengl_texture; + glGenTextures(1, &my_opengl_texture); + glBindTexture(GL_TEXTURE_2D, my_opengl_texture); + glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); + glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); + glPixelStorei(GL_UNPACK_ROW_LENGTH, 0); + glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, image_width, image_height, 0, GL_RGBA, GL_UNSIGNED_BYTE, image_data); + + // Now that we have an OpenGL texture, assuming our imgui rendering function (imgui_impl_xxx.cpp file) takes GLuint as ImTextureID, we can display it: + ImGui::Image((void*)(intptr_t)my_opengl_texture, ImVec2(my_image_width, my_image_height)); + + C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTexture / void*, and vice-versa. + Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTexture / void*. + Examples: + + GLuint my_tex = XXX; + void* my_void_ptr; + my_void_ptr = (void*)(intptr_t)my_tex; // cast a GLuint into a void* (we don't take its address! we literally store the value inside the pointer) + my_tex = (GLuint)(intptr_t)my_void_ptr; // cast a void* into a GLuint + + ID3D11ShaderResourceView* my_dx11_srv = XXX; + void* my_void_ptr; + my_void_ptr = (void*)my_dx11_srv; // cast a ID3D11ShaderResourceView* into an opaque void* + my_dx11_srv = (ID3D11ShaderResourceView*)my_void_ptr; // cast a void* into a ID3D11ShaderResourceView* + + Finally, you may call ImGui::ShowMetricsWindow() to explore/visualize/understand how the ImDrawList are generated. + + Q: How can I have multiple widgets with the same label or without a label? + Q: I have multiple widgets with the same label, and only the first one works. Why is that? + A: A primer on labels and the ID Stack... + + Dear ImGui internally need to uniquely identify UI elements. + Elements that are typically not clickable (such as calls to the Text functions) don't need an ID. + Interactive widgets (such as calls to Button buttons) need a unique ID. + Unique ID are used internally to track active widgets and occasionally associate state to widgets. + Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element. + + - Unique ID are often derived from a string label: + + Button("OK"); // Label = "OK", ID = hash of (..., "OK") + Button("Cancel"); // Label = "Cancel", ID = hash of (..., "Cancel") + + - ID are uniquely scoped within windows, tree nodes, etc. which all pushes to the ID stack.

Both buttons will be treated as the same. + Button("OK"); // ID collision! Interacting with either button will trigger the first one. Fear not! this is easy to solve and there are many ways to solve it! - - When passing a label you can optionally specify extra unique ID information within string itself. + - Solving ID conflict in a simple/local context: + When passing a label you can optionally specify extra ID information within string itself.
