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,

          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, MappingKey-
     board, MappingPointer.  If it is MappingModifier, the modif-
     ier mapping was changed.  If it is MappingKeyboard, the key-
     board 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.
