XAnyEvent(3)			XLIB FUNCTIONS			  XAnyEvent(3)

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.
