XMapEvent(3X11)               SDK X11 R4.11MU05              XMapEvent(3X11)


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.
