XGraphicsExposeEvent(3)                        XLIB FUNCTIONS                        XGraphicsExposeEvent(3)



NAME
       XGraphicsExposeEvent, XNoExposeEvent - GraphicsExpose and NoExpose event structures

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 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 XGraphicsEx-poseEvent XGraphicsExposeEvent
       poseEvent 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 mem-ber member
       ber 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_Cop-yArea X_CopyArea
       yArea 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 coordinates relative to the drawable's origin and indicate the upper-left upperleft
       left corner of the rectangle.  The width and height members are set to the size (extent) of the rec-tangle. rectangle.
       tangle.  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.
