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 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 re-
       quest.  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 use-
       ful to toolkit dispatchers.

       The  XEvent  structure is a union of the	individual structures 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 member,  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 al-
       ways  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 useful to toolkit dispatchers.  To avoid	breaking tool-
       kits, 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 be-
       fore it is used to access any other information in the structure.
