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.
