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). - -// 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 - -// CHANGELOG -// (minor and older changes stripped away, please see git history for details) -// 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. -// 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. - -#include "imgui.h" -#ifndef IMGUI_DISABLE -// FIX(zig-gamedev): -//#include "imgui_impl_glfw.h" - -// Clang warnings with -Weverything -#if defined(__clang__) -#pragma clang diagnostic push -#pragma clang diagnostic ignored "-Wold-style-cast" // warning: use of old-style cast -#pragma clang diagnostic ignored "-Wsign-conversion" // warning: implicit conversion changes signedness -#endif - -// GLFW -#define GLFW_INCLUDE_NONE -#include <GLFW/glfw3.h> - -#ifdef _WIN32 -#undef APIENTRY -#define GLFW_EXPOSE_NATIVE_WIN32 -#include <GLFW/glfw3native.h> // for glfwGetWin32Window() -#endif -#ifdef __APPLE__ -#define GLFW_EXPOSE_NATIVE_COCOA -#include <GLFW/glfw3native.h> // for glfwGetCocoaWindow() -#endif - -#ifdef __EMSCRIPTEN__ -#include <emscripten.h> -#include <emscripten/html5.h> -#endif - -// We gather version tests as define in order to easily see which features are version-dependent. -#define GLFW_VERSION_COMBINED (GLFW_VERSION_MAJOR * 1000 + GLFW_VERSION_MINOR * 100 + GLFW_VERSION_REVISION) -#define GLFW_HAS_WINDOW_TOPMOST (GLFW_VERSION_COMBINED >= 3200) // 3.2+ GLFW_FLOATING -#define GLFW_HAS_WINDOW_HOVERED (GLFW_VERSION_COMBINED >= 3300) // 3.3+ GLFW_HOVERED -#define GLFW_HAS_WINDOW_ALPHA (GLFW_VERSION_COMBINED >= 3300) // 3.3+ glfwSetWindowOpacity -#define GLFW_HAS_PER_MONITOR_DPI (GLFW_VERSION_COMBINED >= 3300) // 3.3+ glfwGetMonitorContentScale -#if defined(__EMSCRIPTEN__) || defined(__SWITCH__) // no Vulkan support in GLFW for Emscripten or homebrew Nintendo Switch -#define GLFW_HAS_VULKAN (0) -#else -#define GLFW_HAS_VULKAN (GLFW_VERSION_COMBINED >= 3200) // 3.2+ glfwCreateWindowSurface -#endif -#define GLFW_HAS_FOCUS_WINDOW (GLFW_VERSION_COMBINED >= 3200) // 3.2+ glfwFocusWindow -#define GLFW_HAS_FOCUS_ON_SHOW (GLFW_VERSION_COMBINED >= 3300) // 3.3+ GLFW_FOCUS_ON_SHOW -#define GLFW_HAS_MONITOR_WORK_AREA (GLFW_VERSION_COMBINED >= 3300) // 3.3+ glfwGetMonitorWorkarea -#define GLFW_HAS_OSX_WINDOW_POS_FIX (GLFW_VERSION_COMBINED >= 3301) // 3.3.1+ Fixed: Resizing window repositions it on MacOS #1553 -#ifdef GLFW_RESIZE_NESW_CURSOR // Let's be nice to people who pulled GLFW between 2019-04-16 (3.4 define) and 2019-11-29 (cursors defines) // FIXME: Remove when GLFW 3.4 is released?
