SDL_GetDisplayUsableBounds

Get the usable desktop area represented by a display.

Header File

Defined in SDL_video.h, but apps should only #include "SDL.h"!

Syntax

int SDL_GetDisplayUsableBounds(int displayIndex, SDL_Rect * rect);

Function Parameters

displayIndex	the index of the display to query the usable bounds from
rect	the SDL_Rect structure filled in with the display bounds

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Remarks

The primary display (displayIndex zero) is always located at 0,0.

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.

The parameter rect is ignored if it is NULL.

This function also returns -1 if the parameter displayIndex is out of range.

Version

This function is available since SDL 2.0.5.
