NAME
     XGraphicsExposeEvent, XNoExposeEvent - GraphicsExpose and
     NoExpose event structures

STRUCTURES
     The structures for GraphicsExpose and NoExpose events con-
     tain:

     typedef struct {
          int type;                /* GraphicsExpose */
          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 */
          Drawable drawable;
          int x, y;
          int width, height;
          int count;               /* if nonzero, at least this many more */
          int major_code;          /* core is CopyArea or CopyPlane */
          int minor_code;          /* not defined in the core */
     } XGraphicsExposeEvent;

     typedef struct {
          int type;                /* NoExpose */
          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 */
          Drawable drawable;
          int major_code;          /* core is CopyArea or CopyPlane */
          int minor_code;          /* not defined in the core */
     } XNoExposeEvent;

     When you receive these events, their 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.

     Both structures have these common members: drawable,
     major_code, and minor_code.  The drawable member is set to
     the drawable of the destination region on which the graphics
     request was to be performed.  The major_code member is set
     to the graphics request initiated by the client and can be

     either X_CopyArea or X_CopyPlane.  If it is X_CopyArea, a
     call to XCopyArea initiated the request.  If it is
     X_CopyPlane, a call to XCopyPlane initiated the request.
     These constants are defined in .  The
     minor_code member, like the major_code member, indicates
     which graphics request was initiated by the client. However,
     the minor_code member is not defined by the core X protocol
     and will be zero in these cases, although it may be used by
     an extension.

     The XGraphicsExposeEvent structure has these additional
     members: x, y, width, height, and count. The x and y members
     are set to the coordinates relative to the drawable'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 Gra-
     phicsExpose events to follow.  If count is zero, no more
     GraphicsExpose events follow for this window.  However, if
     count is nonzero, at least that number of GraphicsExpose
     events (and possibly more) are to follow for this window.
