NAME
XMapEvent, XMappingEvent - MapNotify and MappingNotify event
structures
STRUCTURES
The structure for MapNotify events contains:
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;
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 window that was mapped
or to its parent, depending on whether StructureNotify or
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 True, because these events
usually are generated from pop-ups, which override structure
control.
The structure for MappingNotify events is:
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;
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 request member is set to indicate the kind of mapping
change that occurred and can be MappingModifier, MappingKey-
board, MappingPointer. If it is MappingModifier, the modif-
ier mapping was changed. If it is MappingKeyboard, the key-
board mapping was changed. If it is MappingPointer, the
pointer button mapping was changed. The first_keycode and
count members are set only if the request member was set to
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.
