// 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+ for full feature support.)
|
||||
// (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 will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [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+).
|
||||
// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
|
||||
|
||||
// Issues:
|
||||
// [ ] Platform: Multi-viewport support: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
|
||||
// [ ] Platform: Multi-viewport: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
|
||||
|
||||
// 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.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
// 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).
|

||||
|

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
|
||||
// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after iniitializing 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.
|
||||
// 2024-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
|
||||
// 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)
|
||||
// 2023-01-18: Handle unsupported glfwGetVideoMode() call on e.g. Emscripten.
|
||||
// 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.
