XExposeEvent(3X11)          X Version 11(Release 5)          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.
