Get the usable desktop area represented by a display, in screen coordinates.
Defined in <SDL3/SDL_video.h>
bool SDL_GetDisplayUsableBounds(SDL_DisplayID displayID, SDL_Rect *rect);
SDL_DisplayID | displayID | the instance ID of the display to query. |
SDL_Rect * | rect | the SDL_Rect structure filled in with the display bounds. |
(bool) Returns true on success or false on failure; call SDL_GetError() for more information.
This is the same area as SDL_GetDisplayBounds() reports, but with portions reserved by the system removed. For example, on Apple's macOS, this subtracts the area occupied by the menu bar and dock.
Setting a window to be fullscreen generally bypasses these unusable areas, so these are good guidelines for the maximum space available to a non-fullscreen window.
This function is available since SDL 3.1.3.
