gdk_display_is_rgba (
  GdkDisplay* display

Description [src]

Returns whether surfaces on this display are created with an alpha channel.

Even if a TRUE is returned, it is possible that the surface’s alpha channel won’t be honored when displaying the surface on the screen: in particular, for X an appropriate windowing manager and compositing manager must be running to provide appropriate display. Use gdk_display_is_composited() to check if that is the case.

On modern displays, this value is always TRUE.

Gets propertyGdk.Display:rgba

Return value

Type: gboolean

TRUE if surfaces are created with an alpha channel or FALSE if the display does not support this functionality.
