|

// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
|

// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
|
||||
//-----------------------------------------------------------------------------
|
||||
// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
|
||||
// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
|
||||
//-----------------------------------------------------------------------------
|
||||
// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
|
||||
// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
|
||||
// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
|
||||
// Call IMGUI_CHECKVERSION() from your .cpp files to verify that the data structures your files are using are matching the ones imgui.cpp is using.

// dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)

// Implemented features:

// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!

// You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
|

// **Prefer using the code in imgui_impl_opengl3.cpp**
|
||||
// This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
|
||||
// If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more

// complicated, will require your code to reset every single OpenGL attributes to their initial state, and might

|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-01-03: OpenGL: Backup, setup and restore GL_SHADE_MODEL state, disable GL_STENCIL_TEST and disable GL_NORMAL_ARRAY client state to increase compatibility with legacy OpenGL applications.
|
||||
// 2020-01-23: OpenGL: Backup, setup and restore GL_TEXTURE_ENV to increase compatibility with legacy OpenGL applications.
|
||||
// 2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-08-03: OpenGL: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_opengl2.cpp/.h away from the old combined GLFW/SDL+OpenGL2 examples.
|
||||
// 2018-06-08: OpenGL: 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_ImplOpenGL2_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2017-09-01: OpenGL: Save and restore current polygon mode.
|
||||
// 2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).
|
||||
// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

// 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!

// Modern Desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.

// Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).

// You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
|
||||
|
||||
// About GLSL version:
|
||||
// The 'glsl_version' initialization parameter should be NULL (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"

|

|

// 2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)
|
||||
// 2020-05-25: Misc: Report a zero display-size when window is minimized, to be consistent with other backends.
|
||||
// 2020-02-20: Inputs: Fixed mapping for ImGuiKey_KeyPadEnter (using SDL_SCANCODE_KP_ENTER instead of SDL_SCANCODE_RETURN2).
|
||||
// 2019-12-17: Inputs: On Wayland, use SDL_GetMouseState (because there is no global mouse state).
|
||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-04-23: Inputs: Added support for SDL_GameController (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
|
||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
||||
// 2018-12-21: Inputs: Workaround for Android/iOS which don't seem to handle focus related calls.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-11-14: Changed the signature of ImGui_ImplSDL2_ProcessEvent() to take a 'const SDL_Event*'.
|
||||
// 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_sdl.cpp/.h away from the old combined SDL2+OpenGL/Vulkan examples.
|
||||
// 2018-06-08: Misc: ImGui_ImplSDL2_InitForOpenGL() now takes a SDL_GLContext parameter.
|
||||
// 2018-05-09: Misc: Fixed clipboard paste memory leak (we didn't call SDL_FreeMemory on the data returned by SDL_GetClipboardText).
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
|
||||
// 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.
|
||||
// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
|
||||
// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.

// stb_rect_pack.h - v1.00 - public domain - rectangle packing
|
||||
// Sean Barrett 2014
|
||||
//
|
||||
// Useful for e.g. packing rectangular textures into an atlas.
|
||||
// Does not do rotation.
|
||||
//
|
||||
// Not necessarily the awesomest packing method, but better than
|
||||
// the totally naive one in stb_truetype (which is primarily what
|
||||
// this is meant to replace).
|
||||
//
|
||||
// Has only had a few tests run, may have issues.
|
||||
//
|
||||
// More docs to come.
|
||||
//
|
||||
// No memory allocations; uses qsort() and assert() from stdlib.
|
||||
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
|
||||
//
|
||||
// This library currently uses the Skyline Bottom-Left algorithm.
|
||||
//
|
||||
// Please note: better rectangle packers are welcome! Please
|
||||
// implement them to the same API, but with a different init
|
||||
// function.
