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). - -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. - -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. - -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 ImGui (see example applications for more details). After ImGui is setup, you can use it like in this example: - -![screenshot of sample code alongside its output with ImGui](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/code_sample_01.png) - -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 ImGui with your existing codebase. - -_A common misunderstanding is that some people think immediate mode gui == immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes. Some lazy IMGUI-style librairies uses immediate mode rendering. This is NOT what Dear ImGui does, in fact it does quite the contrary. Those concepts are absolutely unrelated._ - -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! 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, etc. - -Demo ----- - -You should be able to build the examples from sources (tested on Windows/Mac/Linux).

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. - -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 do I update to a newer version of ImGui? -

How can I use the drawing facilities without an ImGui window? (using ImDrawList API) - -See the FAQ in imgui.cpp for answers. - -How do you use ImGui on a platform that may not have a mouse or keyboard? - -I recommend using [Synergy](http://synergy-project.org) ([sources](https://github.com/synergy/synergy)). In particular, the _src/micro/uSynergy.c_ file contains a small client that you can use on any platform to connect to your host PC. You can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate. - -Can you create elaborate/serious tools with ImGui? - -Yes. I have written 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). - -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. Many programmers have unfortunately been taught by their environment to make unnecessarily complicated things. ImGui is about making things that are simple, efficient and powerful. - -Is ImGui fast? - -Probably fast enough for most uses. Down to the foundation of its visual design, 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 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 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 ImGui? - -You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as 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. - -This is [LumixEngine](https://github.com/nem0/LumixEngine) with a minor skinning hack + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged). - -[![Skinning in LumixEngine](https://cloud.githubusercontent.com/assets/8225057/13198792/92808c5c-d812-11e5-9507-16b63918b05b.jpg)](https://cloud.githubusercontent.com/assets/8225057/13044612/59f07aec-d3cf-11e5-8ccb-39adf2e13e69.png) - -Why using C++ (as opposed to C)? - -ImGui takes advantage of a few C++ features for convenience but nothing anywhere Boost-insanity/quagmire. In particular, 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 but could be removed. - -There is an unofficial but reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly. I would suggest using your target language functionality to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. It was really designed with C++ in mind and may not make the same amount of sense with another language.

Prefer reading examples/opengl2_example/ first as it is the simplest. - you may be able to grab and copy a ready made imgui_impl_*** file from the examples/. - - customization: PushStyleColor()/PushStyleVar() or the style editor to tweak the look of the interface (e.g. if you want a more compact UI or a different color scheme). - - - getting started: - - init: call ImGui::GetIO() to retrieve the ImGuiIO structure and fill the fields marked 'Settings'. - - init: call io.Fonts->GetTexDataAsRGBA32(...) and load the font texture pixels into graphics memory. - - every frame: - 1/ in your mainloop or right after you got your keyboard/mouse info, call ImGui::GetIO() and fill the fields marked 'Input' - 2/ call ImGui::NewFrame() as early as you can! - 3/ use any ImGui function you want between NewFrame() and Render() - 4/ call ImGui::Render() as late as you can to end the frame and finalize render data. it will call your RenderDrawListFn handler that you set in the IO structure. - (if you don't need to render, you still need to call Render() and ignore the callback, or call EndFrame() instead. if you call neither some aspects of windows focusing/moving will appear broken.) - - all rendering information are stored into command-lists until ImGui::Render() is called. - - ImGui never touches or know 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 typical application skeleton may be: - - // Application init - ImGuiIO& io = ImGui::GetIO(); - io.DisplaySize.x = 1920.0f; - io.DisplaySize.y = 1280.0f; - io.IniFilename = "imgui.ini"; - io.RenderDrawListsFn = my_render_function; // Setup a render function, or set to NULL and call GetDrawData() after Render() to access the render data. - // TODO: Fill others settings of the io structure - - // Load texture atlas - // There is a default font so you don't need to care about choosing a font yet - unsigned char* pixels; - int width, height; - io.Fonts->GetTexDataAsRGBA32(pixels, &width, &height); - // TODO: At this points you've got a texture pointed to by 'pixels' and you need to upload that your your graphic system - // TODO: Store your texture pointer/identifier (whatever your engine uses) in 'io.Fonts->TexID' - - // Application main loop - while (true) - { - // 1) get low-level inputs (e.g. on Win32, GetKeyboardState(), or poll your events, etc.) - // TODO: fill all fields of IO structure and call NewFrame - ImGuiIO& io = ImGui::GetIO(); - io.DeltaTime = 1.0f/60.0f; - io.MousePos = mouse_pos; - io.MouseDown[0] = mouse_button_0; - io.MouseDown[1] = mouse_button_1; - io.KeysDown[i] = ... - - // 2) call NewFrame(), after this point you can use ImGui::* functions anytime - ImGui::NewFrame(); - - // 3) most of your application code here - MyGameUpdate(); // may use any ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End(); - MyGameRender(); // may use any ImGui functions - - // 4) render & swap video buffers - ImGui::Render(); - SwapBuffers(); - } - - - You can read back 'io.WantCaptureMouse', 'io.WantCaptureKeybord' etc. flags from the IO structure to tell how ImGui intends to use your - inputs and to know if you should share them or hide them from the rest of your application. Read the FAQ below for more information. - - - API BREAKING CHANGES - ==================== - - Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix. - Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code. - Also read releases logs https://github.com/ocornut/imgui/releases for more details. - - - 2016/07/30 (1.50) - 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. - - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. - 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. - ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) - { - float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; - return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); - } - If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. - - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). - - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. - - 2016/05/01 (1.49) - 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. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). - - 2016/04/26 (1.49) - 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. - - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337). - - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) - - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). - - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. - - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. - - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. - - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. - - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. - GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. - GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! - - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize - - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. - - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason - - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. - you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. - - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. - this necessary change will break your rendering function! the fix should be very easy. sorry for that :( - - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. - - the signature of the io.RenderDrawListsFn handler has changed! - ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) - became: - ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). - argument 'cmd_lists' -> 'draw_data->CmdLists' - argument 'cmd_lists_count' -> 'draw_data->CmdListsCount' - ImDrawList 'commands' -> 'CmdBuffer' - ImDrawList 'vtx_buffer' -> 'VtxBuffer' - ImDrawList n/a -> 'IdxBuffer' (new) - ImDrawCmd 'vtx_count' -> 'ElemCount' - ImDrawCmd 'clip_rect' -> 'ClipRect' - ImDrawCmd 'user_callback' -> 'UserCallback' - ImDrawCmd 'texture_id' -> 'TextureId' - - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. - - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! - - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! - - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. - - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). - - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. - - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence - - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry! - - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). - - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). - - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. - - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. - - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). - - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. - - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API - - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. - - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. - - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. - - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing - - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50. - - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing) - - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50. - - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once. - - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now. - - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior - - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing() - - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused) - - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions. - - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader. - (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels. - this sequence: - const void* png_data; - unsigned int png_size; - ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); - // - became: - unsigned char* pixels; - int width, height; - io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); - // - io.Fonts->TexID = (your_texture_identifier); - you now have much more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. - it is now recommended that you sample the font texture with bilinear interpolation. - (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID. - (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix) - (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets - - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver) - - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph) - - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility - - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered() - - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly) - - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity) - - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale() - - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn - - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically) - - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite - - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes - - - FREQUENTLY ASKED QUESTIONS (FAQ), TIPS - ====================================== - - Q: How can I help? - A: - If you are experienced enough with ImGui and with C/C++, look at the todo list and see how you want/can help! - - Become a Patron/donate. Convince your company to become a Patron or provide serious funding for development time. - - Q: How do I update to a newer version of ImGui? - A: Overwrite the following files: - imgui.cpp - imgui.h - imgui_demo.cpp - imgui_draw.cpp - imgui_internal.h - stb_rect_pack.h - stb_textedit.h - stb_truetype.h - Don't overwrite imconfig.h if you have made modification to your copy. - Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. If you have a problem with a function, search for its name - in the code, there will likely be a comment about it. Please report any issue to the GitHub page! - - - Q: What is ImTextureID and how do I display an image? - A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function. - 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. - ImGui will generate the geometry and draw calls using the ImTextureID that you passed and which your renderer can use. - It is your responsibility to get textures uploaded to your GPU. - - Q: I integrated ImGui in my engine and the text or lines are blurry.. - A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f). - Also make sure your orthographic projection matrix and io.DisplaySize matches your actual framebuffer dimension. - - Q: I integrated ImGui in my engine and some elements are clipping or disappearing when I move windows around.. - A: Most likely you are mishandling the clipping rectangles in your render function. Rectangles provided by ImGui are defined as (x1,y1,x2,y2) and NOT as (x1,y1,width,height). - - Q: Can I have multiple widgets with the same label? Can I have widget without a label? (Yes) - A: Yes. A primer on the use of labels/IDs in ImGui.. - - - Elements that are not clickable, such as Text() items don't need an ID. - - - Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget). - to do so they need an unique ID. unique ID are typically derived from a string label, an integer index or a pointer. - - 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. so no conflict can happen if you have two buttons called "OK" in two different windows - or in two different locations of a tree. - - - If you have a same ID twice in the same location, you'll have a conflict: - - Button("OK"); - Button("OK"); // ID collision! Both buttons will be treated as the same. - - 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. This helps solving the simpler collision cases. - use "##" to pass a complement to the ID that won't be visible to the end-user: - - Button("Play"); // Label = "Play", ID = hash of "Play" - Button("Play##foo1"); // Label = "Play", ID = hash of "Play##foo1" (different from above) - Button("Play##foo2"); // Label = "Play", ID = hash of "Play##foo2" (different from above) - - - If you want to completely hide the label, but still need an ID: - - Checkbox("##On", &b); // Label = "", ID = hash of "##On" (no label!) - - - Occasionally/rarely you might want change a label while preserving a constant ID. This allows you to animate labels. - For example you may want to include varying information in a window title bar (and windows are uniquely identified by their ID.. obviously) - Use "###" to pass a label that isn't part of ID: - - Button("Hello###ID"; // Label = "Hello", ID = hash of "ID" - Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above) - - sprintf(buf, "My game (%f FPS)###MyGame"); - Begin(buf); // Variable label, ID = hash of "MyGame" - - - Use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window. - This is the most convenient way of distinguishing ID if you are iterating and creating many UI elements. - You can push a pointer, a string or an integer value. Remember that ID are formed from the concatenation of everything in the ID stack! - - for (int i = 0; i < 100; i++) - { - PushID(i); - Button("Click"); // Label = "Click", ID = hash of integer + "label" (unique) - PopID(); - } - - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj); - Button("Click"); // Label = "Click", ID = hash of pointer + "label" (unique) - PopID(); - } - - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj->Name); - Button("Click"); // Label = "Click", ID = hash of string + "label" (unique) - PopID(); - } - - - More example showing that you can stack multiple prefixes into the ID stack: - - Button("Click"); // Label = "Click", ID = hash of "Click" - PushID("node"); - Button("Click"); // Label = "Click", ID = hash of "node" + "Click" - PushID(my_ptr); - Button("Click"); // Label = "Click", ID = hash of "node" + ptr + "Click" - PopID(); - PopID(); - - - Tree nodes implicitly creates a scope for you by calling PushID(). - - Button("Click"); // Label = "Click", ID = hash of "Click" - if (TreeNode("node")) - { - Button("Click"); // Label = "Click", ID = hash of "node" + "Click" - TreePop(); - } - - - When working with trees, ID are used to preserve the open/close state of each tree node. - Depending on your use cases you may want to use strings, indices or pointers as ID. - e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change. - e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense! - - Q: How can I tell when ImGui wants my mouse/keyboard inputs and when I can pass them to my application? - A: You can read the 'io.WantCaptureXXX' flags in the ImGuiIO structure. Preferably read them after calling ImGui::NewFrame() to avoid those flags lagging by one frame, but either should be fine. - When 'io.WantCaptureMouse' or 'io.WantCaptureKeyboard' flags are set you may want to discard/hide the inputs from the rest of your application. - When 'io.WantInputsCharacters' is set to may want to notify your OS to popup an on-screen keyboard, if available. - ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is a more accurate and complete than testing for ImGui::IsMouseHoveringAnyWindow(). - (Advanced note: text input releases focus on Return 'KeyDown', so the following Return 'KeyUp' event that your application receive will typically have 'io.WantcaptureKeyboard=false'. - Depending on your application logic it may or not be inconvenient. You might want to track which key-downs were for ImGui (e.g. with an array of bool) and filter out the corresponding key-ups.) - - Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13) - A: Use the font atlas to load the TTF file you want: - - ImGuiIO& io = ImGui::GetIO(); - io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); - io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() - - Q: How can I load multiple fonts? - A: Use the font atlas to pack them into a single texture: - (Read extra_fonts/README.txt and the code in ImFontAtlas for more details.) - - ImGuiIO& io = ImGui::GetIO(); - ImFont* font0 = io.Fonts->AddFontDefault(); - ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); - ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels); - io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() - // the first loaded font gets used by default - // use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime - - // Options - ImFontConfig config; - config.OversampleH = 3; - config.OversampleV = 1; - config.GlyphExtraSpacing.x = 1.0f; - io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, &config); - - // Combine multiple fonts into one - ImWchar ranges[] = { 0xf000, 0xf3ff, 0 }; - ImFontConfig config; - config.MergeMode = true; - io.Fonts->AddFontDefault(); - io.Fonts->LoadFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges); - io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese()); - - Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic? - A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. - All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will not work. - In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8. - You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code. - - io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters - io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() - io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application - - As for text input, depends on you passing the right character code to io.AddInputCharacter(). The example applications do that. - - Q: How can I use the drawing facilities without an ImGui window? (using ImDrawList API) - A: The easiest way is to create a dummy window. Call Begin() with NoTitleBar|NoResize|NoMove|NoScrollbar|NoSavedSettings|NoInputs flag, zero background alpha, - then retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like. - - - tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code. - - tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug" - - tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window. this is also useful to set yourself in the context of another window (to get/set other settings) - - tip: you can call Render() multiple times (e.g for VR renders). - - tip: call and read the ShowTestWindow() code in imgui_demo.cpp for more example of how to use ImGui! - - - ISSUES & TODO-LIST - ================== - Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues - The list below consist mostly of notes of things to do before they are requested/discussed by users (at that point it usually happens on the github) - - - doc: add a proper documentation+regression testing system (#435) - - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass. - - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis) (#690) - - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify. - - window: allow resizing of child windows (possibly given min/max for each axis?) - - window: background options for child windows, border option (disable rounding) - - window: add a way to clear an existing window instead of appending (e.g. for tooltip override using a consistent api rather than the deferred tooltip) - - window: resizing from any sides? + mouse cursor directives for app. -!- window: begin with *p_open == false should return false. - - window: get size/pos helpers given names (see discussion in #249) - - window: a collapsed window can be stuck behind the main menu bar? - - window: when window is small, prioritize resize button over close button. - - window: detect extra End() call that pop the "Debug" window out and assert at call site instead of later. - - window/tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic. - - window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd. - - draw-list: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command). -!- scrolling: allow immediately effective change of scroll if we haven't appended items yet - - splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319) - - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. - - widgets: clean up widgets internal toward exposing everything. - - widgets: add disabled and read-only modes (#211) - - main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them. -!- main: make it so that a frame with no window registered won't refocus every window on subsequent frames (~bump LastFrameActive of all windows). - - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes - - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode? - - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. - - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541) - - input text: expose CursorPos in char filter event (#816) - - input text: flag to disable live update of the user buffer (also applies to float/int text input) - - input text: resize behavior - field could stretch when being edited? hover tooltip shows more text? - - input text: add ImGuiInputTextFlags_EnterToApply? (off #218) - - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725) - - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc). - - input text multi-line: way to dynamically grow the buffer without forcing the user to initially allocate for worse case (follow up on #200) - - input text multi-line: line numbers? status bar? (follow up on #200) - - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725) - - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position. - - input number: optional range min/max for Input*() functions - - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled) - - input number: use mouse wheel to step up/down - - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack. - - button: provide a button that looks framed. - - text: proper alignment options - - image/image button: misalignment on padded/bordered button? - - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that? - - layout: horizontal layout helper (#97) - - layout: horizontal flow until no space left (#404) - - layout: more generic alignment state (left/right/centered) for single items? - - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding. - - layout: BeginGroup() needs a border option. - - columns: declare column set (each column: fixed size, %, fill, distribute default size among fills) (#513, #125) - - columns: add a conditional parameter to SetColumnOffset() (#513, #125) - - columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (#125) - - columns: columns header to act as button (~sort op) and allow resize/reorder (#513, #125) - - columns: user specify columns size (#513, #125) - - columns: flag to add horizontal separator above/below? - - columns/layout: setup minimum line height (equivalent of automatically calling AlignFirstTextHeightToWidgets) - - combo: sparse combo boxes (via function call?) / iterators - - combo: contents should extends to fit label if combo widget is small - - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203) - - listbox: multiple selection - - listbox: user may want to initial scroll to focus on the one selected value? - - listbox: keyboard navigation. - - listbox: scrolling should track modified selection. -!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402) - - popups: add variant using global identifier similar to Begin/End (#402) - - popups: border options. richer api like BeginChild() perhaps? (#197) - - tooltip: tooltip that doesn't fit in entire screen seems to lose their "last prefered button" and may teleport when moving mouse - - menus: local shortcuts, global shortcuts (#456, #126) - - menus: icons - - menus: menubars: some sort of priority / effect of main menu-bar on desktop size? - - menus: calling BeginMenu() twice with a same name doesn't seem to append nicely - - statusbar: add a per-window status bar helper similar to what menubar does. - - tabs (#261, #351) - - separator: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y) -!- color: the color helpers/typing is a mess and needs sorting out. - - color: add a better color picker (#346) - - node/graph editor (#306) - - pie menus patterns (#434) - - drag'n drop, dragging helpers (carry dragging info, visualize drag source before clicking, drop target, etc.) (#143, #479) - - plot: PlotLines() should use the polygon-stroke facilities (currently issues with averaging normals) - - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots) - - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value) - - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID) - - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt() - - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). - - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate. - - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign) - - slider & drag: int data passing through a float - - drag float: up/down axis - - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits) - - tree node / optimization: avoid formatting when clipped. - - tree node: tree-node/header right-most side doesn't take account of horizontal scrolling. - - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings? - - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits? - - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer) - - tree node: tweak color scheme to distinguish headers from selected tree node (#581) - - textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249) - - settings: write more decent code to allow saving/loading new fields - - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file - - style: add window shadows. - - style/optimization: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. - - style: color-box not always square? - - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc. - - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation). - - style/opt: PopStyleVar could be optimized by having GetStyleVar returns the type, using a table mapping stylevar enum to data type. - - style: global scale setting. - - style: WindowPadding needs to be EVEN needs the 0.5 multiplier probably have a subtle effect on clip rectangle - - text: simple markup language for color change? - - font: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier. - - font: small opt: for monospace font (like the defalt one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance - - font: add support for kerning, probably optional. perhaps default to (32..128)^2 matrix ~ 36KB then hash fallback. - - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize) - - font: fix AddRemapChar() to work before font has been built. - - log: LogButtons() options for specifying depth and/or hiding depth slider - - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope) - - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard) - - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs. - - filters: set a current filter that tree node can automatically query to hide themselves - - filters: handle wildcards (with implicit leading/trailing *), regexps - - shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus) -!- keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing - - keyboard: full keyboard navigation and focus. (#323) - - focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622) - - focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame) - - input: rework IO system to be able to pass actual ordered/timestamped events. (~#335, #71) - - input: allow to decide and pass explicit double-clicks (e.g. for windows by the CS_DBLCLKS style). - - input: support track pad style scrolling & slider edit. - - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL) - - misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon? - - misc: provide HoveredTime and ActivatedTime to ease the creation of animations. - - style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438) - - style editor: color child window height expressed in multiple of line height. - - remote: make a system like RemoteImGui first-class citizen/project (#75) - - drawlist: move Font, FontSize, FontTexUvWhitePixel inside ImDrawList and make it self-contained (apart from drawing settings?) - - drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack. - - examples: directx9: save/restore device state more thoroughly. - - examples: window minimize, maximize (#583) - - optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335) - - optimization: use another hash function than crc32, e.g. FNV1a - - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)? - - optimization: turn some the various stack vectors into statically-sized arrays - - optimization: better clipping for multi-component widgets -*/ - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#define IMGUI_DEFINE_MATH_OPERATORS -#define IMGUI_DEFINE_PLACEMENT_NEW -#include "imgui_internal.h" - -#include // toupper, isprint -#include // NULL, malloc, free, qsort, atoi -#include // vsnprintf, sscanf, printf -#include // INT_MIN, INT_MAX -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include // intptr_t -#else -#include // intptr_t -#endif - -#ifdef _MSC_VER -#pragma warning (disable: 4127) // condition expression is constant -#pragma warning (disable: 4505) // unreferenced local function has been removed (stb stuff) -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen -#endif - -// Clang warnings with -Weverything -#ifdef __clang__ -#pragma clang diagnostic ignored "-Wold-style-cast" // warning : use of old-style cast // yes, they are more terse. -#pragma clang diagnostic ignored "-Wfloat-equal" // warning : comparing floating point with == or != is unsafe // storing and comparing against same constants ok. -#pragma clang diagnostic ignored "-Wformat-nonliteral" // warning : format string is not a string literal // passing non-literal to vsnformat(). yes, user passing incorrect format strings can crash the code. -#pragma clang diagnostic ignored "-Wexit-time-destructors" // warning : declaration requires an exit-time destructor // exit-time destruction order is undefined. if MemFree() leads to users code that has been disabled before exit it might cause problems.

For this -// reason, it provides an interface that is compatible with computing the -// layout incrementally--we try to make sure we make as few passes through -// as possible. (For example, to locate the mouse pointer in the text, we -// could define functions that return the X and Y positions of characters -// and binary search Y and then X, but if we're doing dynamic layout this -// will run the layout algorithm many times, so instead we manually search -// forward in one pass. Similar logic applies to e.g. up-arrow and -// down-arrow movement.) -// -// If it's run in a widget that *has* cached the layout, then this is less -// efficient, but it's not horrible on modern computers. But you wouldn't -// want to edit million-line files with it. - - -//////////////////////////////////////////////////////////////////////////// -//////////////////////////////////////////////////////////////////////////// -//// -//// Header-file mode -//// -//// - -#ifndef INCLUDE_STB_TEXTEDIT_H -#define INCLUDE_STB_TEXTEDIT_H - -//////////////////////////////////////////////////////////////////////// -// -// STB_TexteditState -// -// Definition of STB_TexteditState which you should store -// per-textfield;

Thus, anti-aliasing of intersecting shapes may look wrong. If -// this turns out to be a problem, you can re-enable the old rasterizer with -// #define STBTT_RASTERIZER_VERSION 1 -// which will incur about a 15% speed hit. -// -// ADDITIONAL DOCUMENTATION -// -// Immediately after this block comment are a series of sample programs. -// -// After the sample programs is the "header file" section. This section -// includes documentation for each API function. -// -// Some important concepts to understand to use this library: -// -// Codepoint -// Characters are defined by unicode codepoints, e.g. 65 is -// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is -// the hiragana for "ma". -// -// Glyph -// A visual character shape (every codepoint is rendered as -// some glyph) -// -// Glyph index -// A font-specific integer ID representing a glyph -// -// Baseline -// Glyph shapes are defined relative to a baseline, which is the -// bottom of uppercase characters. Characters extend both above -// and below the baseline. -// -// Current Point -// As you draw text to the screen, you keep track of a "current point" -// which is the origin of each character. The current point's vertical -// position is the baseline. Even "baked fonts" use this model. -// -// Vertical Font Metrics -// The vertical qualities of the font, used to vertically position -// and space the characters. See docs for stbtt_GetFontVMetrics. -// -// Font Size in Pixels or Points -// The preferred interface for specifying font sizes in stb_truetype -// is to specify how tall the font's vertical extent should be in pixels. -// If that sounds good enough, skip the next paragraph. -// -// Most font APIs instead use "points", which are a common typographic -// measurement for describing font size, defined as 72 points per inch. -// stb_truetype provides a point API for compatibility. However, true -// "per inch" conventions don't make much sense on computer displays -// since they different monitors have different number of pixels per -// inch. For example, Windows traditionally uses a convention that -// there are 96 pixels per inch, thus making 'inch' measurements have -// nothing to do with inches, and thus effectively defining a point to -// be 1.333 pixels. Additionally, the TrueType font data provides -// an explicit scale factor to scale a given font's glyphs to points, -// but the author has observed that this scale factor is often wrong -// for non-commercial fonts, thus making fonts scaled in points -// according to the TrueType spec incoherently sized in practice. -// -// ADVANCED USAGE -// -// Quality: -// -// - Use the functions with Subpixel at the end to allow your characters -// to have subpixel positioning. Since the font is anti-aliased, not -// hinted, this is very import for quality. (This is not possible with -// baked fonts.) -// -// - Kerning is now supported, and if you're supporting subpixel rendering -// then kerning is worth using to give your text a polished look. -// -// Performance: -// -// - Convert Unicode codepoints to glyph indexes and operate on the glyphs; -// if you don't do this, stb_truetype is forced to do the conversion on -// every call. -// -// - There are a lot of memory allocations. We should modify it to take -// a temp buffer and allocate from the temp buffer (without freeing), -// should help performance a lot. -// -// NOTES -// -// The system uses the raw data found in the .ttf file without changing it -// and without building auxiliary data structures. This is a bit inefficient -// on little-endian systems (the data is big-endian), but assuming you're -// caching the bitmaps or glyph shapes this shouldn't be a big deal. -// -// It appears to be very hard to programmatically determine what font a -// given file is in a general way.
