XExposeEvent(3X11)            X11 SDE 5.4R3.00            XExposeEvent(3X11)


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 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 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 member 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 redisplays on events with zero
       counts.
