       XKeymapEvent - KeymapNotify event structure


       The structure for KeymapNotify events contains:

       /* generated on EnterWindow and FocusIn when KeymapState selected */
       typedef struct {
               int type;       /* KeymapNotify */
               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;
               char key_vector[32];
       } XKeymapEvent;

       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 window member is not used but is present to aid some toolkits.  The key_vector  member
       is  set  to  the  bit  vector  of  the  keyboard.   Each  bit  set to 1 indicates that the
       corresponding key is currently pressed.  The vector is represented as 32  bytes.   Byte  N
       (from  0)  contains  the  bits for keys 8N to 8N + 7 with the least significant bit in the
       byte representing key 8N.
