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 siblings.
