// dear imgui: Platform Backend for Windows (standard windows API for 32-bits AND 64-bits applications)
|
||
|
|
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
|
||
|
|
|
||
|
|
// Implemented features:
|
||
|
|
// [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
|
||
|
|
// [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 VK_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||
|
|
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||
|
|
// [X] Platform: Mouse cursor shape and visibility. 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.
|
||
|
|
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
