XExposeEvent(3)			XLIB FUNCTIONS		       XExposeEvent(3)

NAME
       XExposeEvent - Expose event structure

STRUCTURES
       The structure for Expose	events contains:

       typedef struct {
	       int type;       /* Expose */
	       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;
	       int x, y;
	       int width, height;
	       int count;      /* if nonzero, at least this many more */
       } XExposeEvent;

       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 struc-
       ture 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 re-
       quest.  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 use-
       ful to toolkit dispatchers.

       The window member is set	to the exposed (damaged) window.  The x	and y
       members are set to the coordinates relative to the window's origin and
       indicate	the upper-left corner of the rectangle.	 The width and height
       members are set to the size (extent) of the rectangle.  The count mem-
       ber is set to the number	of Expose events that are to follow.  If count
       is zero,	no more	Expose events follow for this window.  However,	if
       count is	nonzero, at least that number of Expose	events (and possibly
       more) follow for	this window.  Simple applications that do not want to
       optimize	redisplay by distinguishing between subareas of	its window can
       just ignore all Expose events with nonzero counts and perform full re-
       displays	on events with zero counts.
