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.
