# Node Editor in ImGui
|
||||
|
||||
[](https://github.com/thedmd/imgui-node-editor/actions/workflows/build.yml)
|
||||
|
||||
## About
|
||||
|
||||
An implementation of node editor with ImGui-like API.
|
||||
|
||||
Project purpose is to serve as a basis for more complex solutions like blueprint editors.
|
||||
|
||||
|
||||
|
||||
Node Editor is build around an idea "draw your content, we do the rest", which mean interactions are handled by editor, content rendering is handled by user. Editor will take care of:
|
||||
* placing your node in the word
|
||||
* dragging nodes
|
||||
* zoom and scrolling
|
||||
* selection
|
||||
* various interaction that can be queried by API (creation, deletion, selection changes, etc.)
|
||||
|
||||
Here are some highlights:
|
||||
* Node movement and selection is handled internally
|
||||
* Node and pin contents are fully customizable
|
||||
* Fully styled, default theme is modeled after UE4 blueprints
|
||||
- Flexible enough to produce such nodes:
|
||||
|
||||
|
||||
|
||||
|
||||
- Customizable links based on Bézier curves:
|
||||
|
||||
|
||||
|
||||
|
||||
* Automatic highlights for nodes, pins and links:
|
||||
|
||||
|
||||
* Smooth navigation and selection
|
||||
* Node state can be saved in user context, so layout will not break
|
||||
* Selection rectangles and group dragging
|
||||
* Context menu support
|
||||
* Basic shortcuts support (cut/copy/paste/delete)
|
||||
* ImGui style API
|
||||
|
||||
Editor is used to implement blueprint editor in Spark CE engine, it proved itself there by allowing to do everything we needed. Therefore it is now slowly moving into stable state from beeing a prototype.
|
||||
|
||||
Note: Project recently was restructured to mimic ImGui layout.
|
||||
|
||||
Please report issues or questions if something isn't clear.
|
||||
|
||||
## Dependencies
|
||||
|
||||
* Vanilla ImGui 1.72+
|
||||
* C++14
|
||||
|
||||
### Dependencies for examples:
|
||||
* https://github.com/thedmd/imgui/tree/feature/layout (used in blueprints sample only)
|
||||
|
||||
### Optional extension you can pull into your local copy of ImGui node editor can take advantage of:
|
||||
* ~~https://github.com/thedmd/imgui/tree/feature/draw-list-fringe-scale (for sharp rendering, while zooming)~~ It is part of ImGui since 1.80 release
|
||||
* https://github.com/thedmd/imgui/tree/feature/extra-keys (for extra shortcuts)
|
||||
|
||||
## Building / Installing
|
||||
|
||||
Node Editor sources are located in root project directory. To use it, simply copy&paste sources into your project. Exactly like you can do with ImGui.
|
||||
|
||||
### Examples
|
||||
[Examples](../examples) can be build with CMake:
|
||||
```
|
||||
Windows:
|
||||
cmake -S examples -B build -G "Visual Studio 15 2017 Win64"
|
||||
or
|
||||
cmake -S examples -B build -G "Visual Studio 16 2019" -A x64
|
||||
|
||||
macOS:
|
||||
cmake -S examples -B build -G "Xcode"
|
||||
|
||||
Linux:
|
||||
cmake -S examples -B build -G "Unix Makefiles"
|
||||
|
||||
Build:
|
||||
cmake --build build --config Release
|
||||
```
|
||||
Executables will be located in `build\bin` directory.
|
||||
|
||||
### Quick Start
|
||||
|
||||
Main node editor header is located in [imgui_node_editor.h](../imgui_node_editor.h).
|
||||
|
||||
Minimal example of one node can be found in [simple-example.cpp](../examples/simple-example/simple-example.cpp).
|
||||
Press 'F' in editor to focus on editor content if you see only grid.
|
||||
```cpp
|
||||
# include <imgui.h>
|
||||
# include <imgui_node_editor.h>
|
||||
# include <application.h>
|
||||
|
||||
namespace ed = ax::NodeEditor;
|
||||
|
||||
struct Example:
|
||||
public Application
|
||||
{
|
||||
using Application::Application;
|
||||
|
||||
void OnStart() override
|
||||
{
|
||||
ed::Config config;
|
||||
config.SettingsFile = "Simple.json";
|
||||
m_Context = ed::CreateEditor(&config);
|
||||
}
|
||||
|
||||
void OnStop() override
|
||||
{
|
||||
ed::DestroyEditor(m_Context);
|
||||
}
|
||||
|
||||
void OnFrame(float deltaTime) override
|
||||
{
|
||||
auto& io = ImGui::GetIO();
|
||||
|
||||
ImGui::Text("FPS: %.2f (%.2gms)", io.Framerate, io.Framerate ? 1000.0f / io.Framerate : 0.0f);
|
||||
|
||||
ImGui::Separator();
|
||||
|
||||
ed::SetCurrentEditor(m_Context);
|
||||
ed::Begin("My Editor", ImVec2(0.0, 0.0f));
|
||||
int uniqueId = 1;
|
||||
// Start drawing nodes.
|
||||
ed::BeginNode(uniqueId++);
|
||||
ImGui::Text("Node A");
|
||||
ed::BeginPin(uniqueId++, ed::PinKind::Input);
|
||||
ImGui::Text("-> In");
|
||||
ed::EndPin();
|
||||
ImGui::SameLine();
|
||||
ed::BeginPin(uniqueId++, ed::PinKind::Output);
|
||||
ImGui::Text("Out ->");
|
||||
ed::EndPin();
|
||||
ed::EndNode();
|
||||
ed::End();
|
||||
ed::SetCurrentEditor(nullptr);
|
||||
|
||||
//ImGui::ShowMetricsWindow();
|
||||
}
|
||||
|
||||
ed::EditorContext* m_Context = nullptr;
|
||||
};
|
||||
|
||||
int Main(int argc, char** argv)
|
||||
{
|
||||
Example exampe("Simple", argc, argv);
|
||||
|
||||
if (exampe.Create())
|
||||
return exampe.Run();
|
||||
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
|
||||

// dear imgui: Renderer for DirectX11
|
||||
// This needs to be used along with a Platform Binding (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
|
||||
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bits indices.
|
||||
|
||||
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
|
||||
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp
|
||||
// https://github.com/ocornut/imgui
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
|
||||
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
|
||||
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2016-05-07: DirectX11: Disabling depth-write.

// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)
|

// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
|

// (Requires: GLFW 3.1+)
|

|
||||
// Implemented features:
|
||||
// [X] Platform: Clipboard support.
|

// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).

|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
|
||||
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
|
||||
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
|
||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
|
||||
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
|
||||
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
|
||||
// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
||||
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
|
||||
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
|
||||
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
|
||||
// - Desktop GL: 2.x 3.x 4.x
|
||||
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
|
||||
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [x] Renderer: Large meshes support (64k+ vertices) with 16-bit indices (Desktop OpenGL only).
|
||||
|
||||
// About WebGL/ES:
|
||||
// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
|
||||
// - This is done automatically on iOS, Android and Emscripten targets.
|
||||
// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// Learn about Dear ImGui:
|
||||
// - FAQ https://dearimgui.com/faq
|
||||
// - Getting Started https://dearimgui.com/getting-started
|
||||
// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
|
||||
// - Introduction, links and more at the top of imgui.cpp
|
||||
|
||||
// About GLSL version:
|
||||
// The 'glsl_version' initialization parameter should be nullptr (default) or a "#version XXX" string.
|
||||
// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
|
||||
// Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

// Widget Example
|
||||
// Drawing standard ImGui widgets inside the node body
|
||||
//
|
||||
// First, some unsorted notes about which widgets do and don't draw well inside nodes. Run the examples to see all the allowed widgets.
|
||||
//
|
||||
// - Child windows with scrolling doesn't work in the node. The child window appears in a normal node,
|
||||
// and scrolls, but its contents are floating around in the wrong location, and they are not scaled.
|
||||
// Note that you can put scrolling child windows into "deferred popups" (see next item).
|
||||
// - Listboxes and combo-boxes only work in nodes with a work-around: deferring the popup calls until after the node drawing is
|
||||
// completed. Look to the popup-demo for an example.
|
||||
// - Headers and trees work inside the nodes only with hacks. This is because they attempt to span the "avaialbe width"
|
||||
// and the nodes can't tell these widgets how wide it is. The work-around is to set up a fake
|
||||
// table with a static column width, then draw your header and tree widgets in that column.
|
||||
// - Clickable tabs don't work in nodes. Tabs appear, but you cannot actually change the tab, so they're functionally useless.
|
||||
// - Editable text areas work, but you have to manually manage disabling the editor shorcuts while typing is detected.
|
||||
// Look around for the call to ed::EnableShortcuts() for an example.
|
||||
// - Most of the cool graph widgets can't be used because they are hard-coded in ImGui to spawn tooltips, which don't work.

// Canvas widget - view over infinite virtual space.
|
||||
//
|
||||
// Canvas allows you to draw your widgets anywhere over infinite space and provide
|
||||
// view over it with support for panning and scaling.
|
||||
//
|
||||
// When you enter a canvas ImGui is moved to virtual space which mean:
|
||||
// - ImGui::GetCursorScreenPos() return (0, 0) and which correspond to top left corner
|
||||
// of the canvas on the screen (this can be changed using CanvasView()).
|
||||
// - Mouse input is brought to canvas space, so widgets works as usual.
|
||||
// - Everything you draw with ImDrawList will be in virtual space.
|
||||
//
|
||||
// By default origin point is on top left corner of canvas widget. It can be
|
||||
// changed with call to CanvasView() where you can specify what part of space
|
||||
// should be viewed by setting viewport origin point and scale. Current state
|
||||
// can be queried with CanvasViewOrigin() and CanvasViewScale().
|
||||
//
|
||||
// Viewport size is controlled by 'size' parameter in BeginCanvas(). You can query
|
||||
// it using CanvasContentMin/Max/Size functions. They are useful if you to not specify
|
||||
// canvas size in which case all free space is used.
|
||||
//
|
||||
// Bounds of visible region of infinite space can be queried using CanvasViewMin/Max/Size
|
||||
// functions. Everything that is drawn outside of this region will be clipped
|
||||
// as usual in ImGui.
|
||||
//
|
||||
// While drawing inside canvas you can translate position from world (usual ImGui space)
|
||||
// to virtual space and back using CanvasFromWorld()/CanvasToWorld().
|
||||
//
|
||||
// Canvas can be nested in each other (they are regular widgets after all). There
|
||||
// is a way to transform position between current and parent canvas with
|
||||
// CanvasFromParent()/CanvasToParent().
|
||||
//
|
||||
// Sometimes in more elaborate scenarios you want to move out canvas virtual space,
|
||||
// do something and came back. You can do that with SuspendCanvas() and ResumeCanvas().
|
||||
//
|
||||
// Note:
|
||||
// It is not valid to call canvas API outside of BeginCanvas() / EndCanvas() scope.

// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
|

// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.

// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.

// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always calling io.AddKeyModsEvent() next and before key event (not in NewFrame) to fix input queue with very low framerates.
|

// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|

// 2021-12-08: Renderer: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.

// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
|

// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).

// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)

// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
|
||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).

// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX12: Change blending equation to preserve alpha in output buffer.
|
||||
// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
|
||||
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
|
||||
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
|
||||
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
|
||||
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.

|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
|
||||
// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
|
||||
// 2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
|
||||
// 2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
|
||||
// 2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.
|
||||
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
|
||||
// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
