NAME
XAnyEvent, XEvent - generic X event structures
STRUCTURES
All the event structures declared in
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
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 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;
