// dear imgui: Platform Binding for GLFW
|
||||
// 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'. FIXME: 3 cursors types are missing from GLFW.
|
||||
// [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
|
||||
|
||||
// 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)
|
||||
// 2019-07-21: 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.

|

// - 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 Binding (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 in imgui.cpp.
|
||||
// [x] Renderer: Desktop GL only: 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)
|
||||
// 2019-09-22: OpenGL: Detect default GL loader using __has_include compiler facility.
|
||||
// 2019-09-16: OpenGL: Tweak initialization code to allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() before the first NewFrame() call.
|
||||
// 2019-05-29: OpenGL: Desktop GL only: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: OpenGL: Not calling glBindBuffer more than necessary in the render loop.
|
||||
// 2019-03-15: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early.
|
||||
// 2019-03-03: OpenGL: Fix support for ES 2.0 (WebGL 1.0).
|
||||
// 2019-02-20: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN even if defined by the headers/loader.
|
||||
// 2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
|
||||
// 2019-02-01: OpenGL: Using GLSL 410 shaders for any version over 410 (e.g. 430, 450).
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-11-13: OpenGL: Support for GL 4.5's glClipControl(GL_UPPER_LEFT) / GL_CLIP_ORIGIN.
|
||||
// 2018-08-29: OpenGL: Added support for more OpenGL loaders: glew and glad, with comments indicative that any loader can be used.
|
||||
// 2018-08-09: OpenGL: Default to OpenGL ES 3 on iOS and Android. GLSL version default to "#version 300 ES".
|
||||
// 2018-07-30: OpenGL: Support for GLSL 300 ES and 410 core. Fixes for Emscripten compilation.
|
||||
// 2018-07-10: OpenGL: Support for more GLSL versions (based on the GLSL version string). Added error output when shaders fail to compile/link.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_opengl3.cpp/.h away from the old combined GLFW/SDL+OpenGL3 examples.
|
||||
// 2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-05-25: OpenGL: Removed unnecessary backup/restore of GL_ELEMENT_ARRAY_BUFFER_BINDING since this is part of the VAO state.
|
||||
// 2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer.
|
||||
// 2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150".
|
||||
// 2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150.
|
||||
// 2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
|
||||
// 2017-05-01: OpenGL: Fixed save and restore of current blend func state.
|
||||
// 2017-05-01: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.
|
