STRUCTURES

       The structures for GraphicsExpose and NoExpose events contain:

       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 fol-
       lows.

       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
       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 destina-
       tion 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_Copy-
       Area, 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 exten-
       lateEvent(3X11), XCirculateRequestEvent(3X11), XColormapEvent(3X11),
       XConfigureEvent(3X11), XConfigureRequestEvent(3X11), XCopyArea(3X11),
       XCrossingEvent(3X11), XDestroyWindowEvent(3X11), XErrorEvent(3X11),
       XExposeEvent(3X11), XFocusChangeEvent(3X11), XGravityEvent(3X11),
       XKeymapEvent(3X11), XMapEvent(3X11), XMapRequestEvent(3X11), XProper-
       tyEvent(3X11), XReparentEvent(3X11), XResizeRequestEvent(3X11), XSelec-
       tionClearEvent(3X11), XSelectionEvent(3X11), XSelectionRe-
       questEvent(3X11), XUnmapEvent(3X11), XVisibilityEvent(3X11)
