| // dear imgui: Platform Backend for SDL3 (*EXPERIMENTAL*) |
| // This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..) |
| // (Info: SDL3 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.) |
| |
| // (**IMPORTANT: SDL 3.0.0 is NOT YET RELEASED AND CURRENTLY HAS A FAST CHANGING API. THIS CODE BREAKS OFTEN AS SDL3 CHANGES.**) |
| |
| // Implemented features: |
| // [X] Platform: Clipboard support. |
| // [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen. |
| // [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 SDL_SCANCODE_* 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. |
| // 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) |
| // 2024-10-24: Emscripten: SDL_EVENT_MOUSE_WHEEL event doesn't require dividing by 100.0f on Emscripten. |
| // 2024-09-03: Update for SDL3 api changes: SDL_GetGamepads() memory ownership revert. (#7918, #7898, #7807) |
| // 2024-08-22: moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO: |
| // - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn |
| // - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn |
| // - io.PlatformSetImeDataFn -> platform_io.Platform_SetImeDataFn |
| // 2024-08-19: Storing SDL_WindowID inside ImGuiViewport::PlatformHandle instead of SDL_Window*. |
| // 2024-08-19: ImGui_ImplSDL3_ProcessEvent() now ignores events intended for other SDL windows. (#7853) |
| // 2024-07-22: Update for SDL3 api changes: SDL_GetGamepads() memory ownership change. (#7807) |
| // 2024-07-18: Update for SDL3 api changes: SDL_GetClipboardText() memory ownership change. (#7801) |
| // 2024-07-15: Update for SDL3 api changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794) |
| // 2024-07-02: Update for SDL3 api changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762). |
| // 2024-07-01: Update for SDL3 api changes: SDL_SetTextInputRect() changed to SDL_SetTextInputArea(). |
| // 2024-06-26: Update for SDL3 api changes: SDL_StartTextInput()/SDL_StopTextInput()/SDL_SetTextInputRect() functions signatures. |
| // 2024-06-24: Update for SDL3 api changes: SDL_EVENT_KEY_DOWN/SDL_EVENT_KEY_UP contents. |
| // 2024-06-03; Update for SDL3 api changes: SDL_SYSTEM_CURSOR_ renames. |
| // 2024-05-15: Update for SDL3 api changes: SDLK_ renames. |
| // 2024-04-15: Inputs: Re-enable calling SDL_StartTextInput()/SDL_StopTextInput() as SDL3 no longer enables it by default and should play nicer with IME. |
| // 2024-02-13: Inputs: Fixed gamepad support. Handle gamepad disconnection. Added ImGui_ImplSDL3_SetGamepadMode(). |
| // 2023-11-13: Updated for recent SDL3 API changes. |
| // 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys. |
| // 2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391) |
| // 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306) |
| // 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702) |
| // 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644) |
| // 2023-02-07: Forked "imgui_impl_sdl2" into "imgui_impl_sdl3". Removed version checks for old feature. Refer to imgui_impl_sdl2.cpp for older changelog. |
