When you receive this event, the structure members are set as follows.
The type member is set to the event type constant name that uniquely identifies it. For example, when the X server reports a GraphicsExpose event to a client application, it sends an XGraphicsExposeEvent structure with the type member set to GraphicsExpose. The display member is set to a pointer to the display the event was read on. The send_event member is set to True if the event came from a SendEvent protocol request. The serial member is set from the serial number reported in the protocol but expanded from the 16-bit least-significant bits to a full 32-bit value. The window member is set to the window that is most useful to toolkit dispatchers.
The event member is set either to the unmapped window or to its parent, depending on whether StructureNotify or SubstructureNotify was selected. This is the window used by the X server to report the event. The window member is set to the window that was unmapped. The from_configure member is set to True if the event was generated as a result of a resizing of the window's parent when the window itself had a win_gravity of UnmapGravity.
