NAME
       XAnyEvent, XEvent - generic X event structures

STRUCTURES
       All the event structures declared in <X11/Xlib.h> have the
       following common members:
       typedef struct {
	    int type;
	    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;
       } XAnyEvent;

       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 applica
       tion, 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 XEvent structure is a union of the individual struc
       tures declared for each event type:
       typedef union _XEvent {
	    int type;		     /* must not be changed */
	    XAnyEvent xany;
	    XKeyEvent xkey;
	    XButtonEvent xbutton;
	    XMotionEvent xmotion;
	    XCrossingEvent xcrossing;
	    XFocusChangeEvent xfocus;
	    XExposeEvent xexpose;
	    XGraphicsExposeEvent xgraphicsexpose;
	    XNoExposeEvent xnoexpose;
	    XVisibilityEvent xvisibility;
	    XCreateWindowEvent xcreatewindow;
	    XDestroyWindowEvent xdestroywindow;
	    XUnmapEvent xunmap;
	    XMapEvent xmap;
	    XMapRequestEvent xmaprequest;
	    XReparentEvent xreparent;
	    XConfigureEvent xconfigure;
	    XGravityEvent xgravity;
	    XResizeRequestEvent xresizerequest;
	    XConfigureRequestEvent xconfigurerequest;
	    XCirculateEvent xcirculate;
	    XCirculateRequestEvent xcirculaterequest;
	    XPropertyEvent xproperty;

	    XSelectionClearEvent xselectionclear;
	    XSelectionRequestEvent xselectionrequest;
	    XSelectionEvent xselection;
	    XColormapEvent xcolormap;
	    XClientMessageEvent xclient;
	    XMappingEvent xmapping;
	    XErrorEvent xerror;
	    XKeymapEvent xkeymap;
	    long pad[24];
       } XEvent;

       An XEvent structure's first entry always is the type mem
       ber, which is set to the event type.  The second member
       always is the serial number of the protocol request that
       generated the event.  The third member always is
       send_event, which is a Bool that indicates if the event
       was sent by a different client.	The fourth member always
       is a display, which is the display that the event was read
       from.  Except for keymap events, the fifth member always
       is a window, which has been carefully selected to be use
       ful to toolkit dispatchers.  To avoid breaking toolkits,
       the order of these first five entries is not to change.
       Most events also contain a time member, which is the time
       at which an event occurred.  In addition, a pointer to the
       generic event must be cast before it is used to access any
       other information in the structure.
