XMapEvent(3) XLIB FUNCTIONS XMapEvent(3)
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 struc-
ture 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 usu-
ally 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 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 GraphicsExpose
event to a client application, it sends an XGraphicsExposeEvent struc-
ture 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, MappingKeyboard, MappingPointer.
If it is MappingModifier, the modifier mapping was changed. If it is
MappingKeyboard, the keyboard mapping was changed. If it is Mapping-
Pointer, the pointer button mapping was changed. The first_keycode and
count members are set only if the request member was set to MappingKey-
board. The number in first_keycode represents the first number in the
range of the altered mapping, and count represents the number of key-
codes altered.
