The unmap_event signal will be emitted when the widget's window is unmapped.
A window is unmapped when it becomes invisible on the screen.
To receive this signal, the Window associated to the widget needs to enable the STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows.
