.SH NAME
XMapEvent, XMappingEvent \- MapNotify and MappingNotify event structures
.SH STRUCTURES
The structure for
.ZN MapNotify
events contains:
.LP
.Ds 0
.TA .5i 3i
.ta .5i 3i
typedef struct {
	int type;	/\&* MapNotify */
	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 override_redirect;	/\&* boolean, is override set... */
} XMapEvent;
.De
.LP
When you receive this event,
the structure members are set as follows.
.LP
The type member is set to the event type constant name that uniquely identifies
it.
For example, when the X server reports a
.ZN GraphicsExpose
event to a client application, it sends an
.ZN XGraphicsExposeEvent
structure with the type member set to
.ZN GraphicsExpose .
The display member is set to a pointer to the display the event was read on.
The send_event member is set to
.ZN True
if the event came from a
.ZN 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.
.LP
The event member is set either to the window that was mapped or to its parent,
depending on whether
.ZN StructureNotify
or
.ZN SubstructureNotify
was selected.
The window member is set to the window that was mapped.
The override_redirect member is set to the override-redirect attribute
of the window.
Window manager clients normally should ignore this window 
if the override-redirect attribute is
.ZN True ,
because these events usually are generated from pop-ups,
which override structure control.
.LP
The structure for
.ZN MappingNotify
events is:
.LP
.Ds 0
.TA .5i 3i
.ta .5i 3i
typedef struct {
	int type;	/\&* MappingNotify */
	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 window;	/\&* unused */
	int request;	/\&* one of MappingModifier, MappingKeyboard,
		   MappingPointer */
	int first_keycode;	/\&* first keycode */
	int count;	/\&* defines range of change w. first_keycode*/
} XMappingEvent;
.De
.LP
When you receive this event,
the structure members are set as follows.
.LP
The type member is set to the event type constant name that uniquely identifies
it.
For example, when the X server reports a
.ZN GraphicsExpose
event to a client application, it sends an
.ZN XGraphicsExposeEvent
structure with the type member set to
.ZN GraphicsExpose .

.ZN True
if the event came from a
.ZN 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.
.LP
The request member is set to indicate the kind of mapping change that occurred
and can be
.ZN MappingModifier ,
.ZN MappingKeyboard ,
.ZN MappingPointer .
If it is
.ZN MappingModifier ,
the modifier mapping was changed.
If it is
.ZN MappingKeyboard ,
the keyboard mapping was changed.
If it is
.ZN MappingPointer ,
the pointer button mapping was changed. 
The first_keycode and count members are set only 
if the request member was set to
.ZN MappingKeyboard .
The number in first_keycode represents the first number in the range 
of the altered mapping, 
and count represents the number of keycodes altered.
