public class EventVisibility : Event
Warning: EventVisibility is deprecated since 3.12.
Generated when the window visibility status has changed.
Modern composited windowing systems with pervasive transparency make it impossible to track the visibility of a window reliably, so this event can not be guaranteed to provide useful information.
