XMapEvent, XMappingEvent
- MapNotify and MappingNotify event structures
The structure for
MapNotify events contains:
0
0>=40 .vs 0u
0<=39 .vs 0p
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:
0
0>=40 .vs 0u
0<=39 .vs 0p
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, MappingKeyboard, MappingPointer. If it is
MappingModifier, the modifier mapping was changed. If it is MappingKeyboard,
the keyboard 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.
