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, 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.
