a The state member is set to the state of the window's visibility and can be VisibilityUnobscured, VisibilityPartiallyObscured, or VisibilityFullyObscured. The X server ignores all of a window's subwindows when determining the visibility state of the window and processes VisibilityNotify events according to the following: When the window changes state from partially obscured, fully obscured, or not viewable to viewable and completely unobscured, the X server generates the event with the state member of the EventVisibility structure set to Gdk.Visibility.Unobscured. When the window changes state from viewable and completely unob- scured or not viewable to viewable and partially obscured, the X server generates the event with the state member of the XVisibili- tyEvent structure set to Gdk.Visibility.Partial. When the window changes state from viewable and completely unobscured, viewable and partially obscured, or not viewable to viewable and fully obscured, the X server generates the event with the state member of the XVisibilityEvent structure set to Gdk.Visibility.FullyObscured.
