1// dear imgui: Platform Binding for GLFW
2// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)
3// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
4// (Requires: GLFW 3.1+)
5
6// Implemented features:
7// [X] Platform: Clipboard support.
8// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
9// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
10// [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
11
12// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
13// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
14// https://github.com/ocornut/imgui

16// CHANGELOG
17// (minor and older changes stripped away, please see git history for details)
18// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
19// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
20// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
21// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
22// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
23// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
24// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
25// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
26// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
27// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
28// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
29// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
30// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
31// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
32// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
33// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
34// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
35// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
36// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
37// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
38// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
