To receive
UnmapNotify
events, set the
StructureNotifyMask
bit in the event-mask attribute of the window or the
SubstructureNotifyMask
bit in the event-mask attribute of the parent window
(in which case, unmapping any child window generates an event).
The structure for this event type contains:
typedef struct {
int type; /* UnmapNotify */
unsigned long serial; /* # of last request processed by server */
Bool send_event; /* true if this came from a SendEvent request */
Display *display; /* Display the event was read from */
Window event;
Window window;
Bool from_configure;
} XUnmapEvent;
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.
