.SH NAME
|
|
XMapEvent, XMappingEvent \- MapNotify and MappingNotify event structures
|
|
.SH STRUCTURES
|
|
The structure for
|
|
.ZN MapNotify
|
|
events contains:
|
|
.LP
|
|
.Ds 0
|
|
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;
|
|
.De
|
|
.LP
|
|
When you receive this event,
|
|
the structure members are set as follows.
|
|
.LP
|
|
The type member is set to the event type constant name that uniquely identifies
|
|
it.
|
|
For example, when the X server reports a
|
|
.ZN GraphicsExpose
|
|
event to a client application, it sends an
|
|
.ZN XGraphicsExposeEvent
|
|
structure with the type member set to
|
|
.ZN GraphicsExpose .
|
|
The display member is set to a pointer to the display the event was read on.
|
|
The send_event member is set to
|
|
.ZN True
|
|
if the event came from a
|
|
.ZN 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.
|
|
.LP
|
|
The event member is set either to the window that was mapped or to its parent,
|
|
depending on whether
|
|
.ZN StructureNotify
|
|
or
|
|
.ZN 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
|
|
.ZN True ,
|
|
because these events usually are generated from pop-ups,
|
|
which override structure control.
|
|
.LP
|
|
The structure for
|
|
.ZN MappingNotify
|
|
events is:
|
|
.LP
|
|
.Ds 0
|
|
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;
|
|
.De
|
|
.LP
|
|
When you receive this event,
|
|
the structure members are set as follows.
|
|
.LP
|
|
The type member is set to the event type constant name that uniquely identifies
|
|
it.
|
|
For example, when the X server reports a
|
|
.ZN GraphicsExpose
|
|
event to a client application, it sends an
|
|
.ZN XGraphicsExposeEvent
|
|
structure with the type member set to
|
|
.ZN GraphicsExpose .
|
|
The display member is set to a pointer to the display the event was read on.
|
|
The send_event member is set to
|
|
.ZN True
|
|
if the event came from a
|
|
.ZN 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.
|
|
.LP
|
|
The request member is set to indicate the kind of mapping change that occurred
|
|
and can be
|
|
.ZN MappingModifier ,
|
|
.ZN MappingKeyboard ,
|
|
.ZN MappingPointer .
|
|
If it is
|
|
.ZN MappingModifier ,
|
|
the modifier mapping was changed.
|
|
If it is
|
|
.ZN MappingKeyboard ,
|
|
the keyboard mapping was changed.
|
|
If it is
|
|
.ZN MappingPointer ,
|
|
the pointer button mapping was changed.
|
|
The first_keycode and count members are set only
|
|
if the request member was set to
|
|
.ZN 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.
