XMapEvent(3X11)     X Version 11 (Release 4)      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.
