NAME
       XGraphicsExposeEvent, XNoExposeEvent - GraphicsExpose and NoExpose event structures

STRUCTURES
       The structures for GraphicsExpose and NoExpose events contain:

       typedef struct {
	    int type;
	    unsigned long serial;
	    Bool send_event;
	    Display *display;
	    Drawable drawable;
	    int x, y;
	    int width, height;
	    int count;
	    int major_code;
	    int minor_code;
       } XGraphicsExposeEvent;

       typedef struct {
	    int type;
	    unsigned long serial;
	    Bool send_event;
	    Display *display;
	    Drawable drawable;
	    int major_code;
	    int minor_code;
       } 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 GraphicsEx-
       pose 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 desti-
       nation 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 <X11/Xproto.h>.  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 coor-
       dinates 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 GraphicsExpose 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.
