// DEAR IMGUI COMPILE-TIME OPTIONS
|
||||
// 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 file to verify that the data structures your files are using are matching the ones imgui.cpp is using.

// dear imgui: Platform Backend for GLFW
|
||||
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
|
||||
// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
|
||||
// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ or GLFW 3.4+ for full feature support.)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Platform: Clipboard support.
|
||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
|
||||
// [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 GLFW_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
|
||||
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Resizing cursors requires GLFW 3.4+! Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
|
||||
// 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 Emscripten support:
|
||||
// - Emscripten provides its own GLFW (3.2.1) implementation (syntax: "-sUSE_GLFW=3"), but Joystick is broken and several features are not supported (multiple windows, clipboard, timer, etc.)
|
||||
// - A third-party Emscripten GLFW (3.4.0) implementation (syntax: "--use-port=contrib.glfw3") fixes the Joystick issue and implements all relevant features for the browser.
|
||||
// See https://github.com/pongasoft/emscripten-glfw/blob/master/docs/Comparison.md for details.
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2024-08-22: moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
|
||||
// - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn
|
||||
// - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn
|
||||
// - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn
|
||||
// 2024-07-31: Added ImGui_ImplGlfw_Sleep() helper function for usage by our examples app, since GLFW doesn't provide one.
|
||||
// 2024-07-08: *BREAKING* Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback to ImGui_ImplGlfw_InstallEmscriptenCallbacks(), added GLFWWindow* parameter.
|
||||
// 2024-07-08: Emscripten: Added support for GLFW3 contrib port (GLFW 3.4.0 features + bug fixes): to enable, replace -sUSE_GLFW=3 with --use-port=contrib.glfw3 (requires emscripten 3.1.59+) (https://github.com/pongasoft/emscripten-glfw)
|
||||
// 2024-07-02: Emscripten: Added io.PlatformOpenInShellFn() handler for Emscripten versions.
|
||||
// 2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
|
||||
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
|
||||
// 2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
|
||||
// 2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
|
||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)
|
||||
// 2023-03-16: Inputs: Fixed key modifiers handling on secondary viewports (docking branch). Broken on 2023/01/04. (#6248, #6034)
|
||||
// 2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
|
||||
// 2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
|
||||
// 2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
|
||||
// 2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
|
||||
// 2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
|
||||
// 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).
|
||||
// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position *EDIT* Reverted 2023-07-18.
|
||||
// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
|
||||
// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
|
||||
// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
|
||||
// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
|
||||
// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
|
||||
// 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).
|
||||
// 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.

// 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.
|

// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.
|
