When Generated

A PropertyNotify event indicates that a property of a window has changed or been deleted. This event can also be used to get the current server time (by appending zero-length data to a property). PropertyNotify events are generated by XChangeProperty(), XDeleteProperty(), XGetWindowProperty(), or XRotateWindowProperties().
