Add SDL3Swift wrappers for OpenGL, keyboard, mouse, and misc APIs#13
Merged
Conversation
Wraps SDL_GL_CreateContext/MakeCurrent/DestroyContext/SwapWindow and the attribute get/set + swap interval APIs, which had no coverage before.
Wraps SDL_GetKeyboardState/SDL_GetScancodeName and adds ~50 named Scancode constants for keybinding use cases.
Wraps SDL_GetMouseState/GetRelativeMouseState and window relative-mouse-mode and mouse-grab setters.
Adds SDL_GetGamepadName/Properties/RumbleGamepad/SetGamepadPlayerIndex, axis/button string lookups, and the mapping-file/isGamepad helpers.
Adds SDL_SetWindowFullscreen, SDL_GetWindowPosition, and SDL_SyncWindow.
Needed as the return type for the new display bounds accessors.
Adds SDL_GetDisplayBounds/GetDisplayUsableBounds/GetDisplayForWindow and SDL_GetCurrentVideoDriver.
Wraps SDL_GetTicks/SDL_Delay (millisecond variants, alongside SDL's existing nanosecond wrappers) and SDL_GetCurrentTime/SDL_TimeToDateTime.
SDL's logging functions are C-variadic and unavailable in Swift, so this routes through SDL_LogMessageV via withVaList with a fixed "%s" format.
Wraps SDL_ShowSimpleMessageBox.
Wraps SDL_GetBooleanProperty, used by Gamepad.hasRumble.
Wraps SDL_GetJoysticks/SDL_GetJoystickNameForID, distinct from the higher-level Gamepad API.
Adds SDL_EVENT_MOUSE_WHEEL, SDL_EVENT_TEXT_INPUT, and SDL_EVENT_WINDOW_CLOSE_REQUESTED cases, previously falling through to .unknown.
