Function sdl2_sys::SDL_GetDisplayUsableBounds

source ·

pub unsafe extern "C" fn SDL_GetDisplayUsableBounds(
    displayIndex: c_int,
    rect: *mut SDL_Rect
) -> c_int

Expand description

Get the usable desktop area represented by a display.

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.

\param displayIndex the index of the display to query the usable bounds from \param rect the SDL_Rect structure filled in with the display bounds \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.5.
