       XCirculateEvent - CirculateNotify event structure


       The structure for CirculateNotify events contains:

       typedef struct {
               int type;       /* CirculateNotify */
               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;
               int place;      /* PlaceOnTop, PlaceOnBottom */
       } XCirculateEvent;

       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 restacked window or  to  its  parent,  depending  on
       whether  StructureNotify  or SubstructureNotify was selected.  The window member is set to
       the window that was restacked.  The place member is set to the window's position after the
       restack occurs and is either PlaceOnTop or PlaceOnBottom.  If it is PlaceOnTop, the window
       is now on top of all siblings.  If it is  PlaceOnBottom,  the  window  is  now  below  all
