Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy AKEYCODE_* values are obsolete since 1.87 and not supported since 1.91.5] -// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen. -// Missing features or Issues: -// [ ] Platform: Clipboard support. -// [ ] Platform: Gamepad support. -// [ ] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: Check if this is even possible with Android. -// Important: -// - Consider using SDL or GLFW backend on Android, which will be more full-featured than this. -// - FIXME: On-screen keyboard currently needs to be enabled by the application (see examples/ and issue #3446) -// - FIXME: Unicode character inputs needs to be passed by Dear ImGui by the application (see examples/ and issue #3446) - -// You can use unmodified imgui_impl_* files in your project.
