XMapEvent, XMappingEvent - MapNotify and MappingNotify event structures
Structures
The structure for events contains:
typedef struct {
int type; /* MapNotify */
unsigned long serial; /* # of last request processed by
server */
Bool send_event; /* true if 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;
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 event to a
client application, it sends an structure with the type member set to The display member is set to a pointer to the display the event was
read on. The send_event member is set to if the event came from a 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 win-
dow that is most useful to toolkit dispatchers.
The event member is set either to the window that was mapped or to its parent, depending on whether or 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 because these events usually are generated from pop-ups,
which override structure control.
The structure for events is:
typedef struct
int type; /* MappingNotify */
unsigned long serial; /* # of last request processed by
server */
Bool send_event; /* true if 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 with
first_keycode*/
} XMappingEvent;
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 event to a

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 win-
dow that is most useful to toolkit dispatchers.
The request member is set to indicate the kind of mapping change that occurred and can be If it is the modifier mapping was changed. If it
is the keyboard mapping was changed. If it is the pointer button mapping was changed. The first_keycode and count members are set only if
the request member was set to The number in first_keycode represents the first number in the range of the altered mapping, and count repre-
sents the number of keycodes altered.
