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 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 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.
