|
|
.SH NAME
|
|
XAnyEvent, XEvent \- generic X event structures
|
|
.SH STRUCTURES
|
|
All the event structures declared in
|
|
.Pn < X11/Xlib.h >
|
|
have the following common members:
|
|
.Ds 0
|
|
.TA .5i 3i
|
|
.ta .5i 3i
|
|
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;
|
|
.De
|
|
.LP
|
|
The type member is set to the event type constant name that uniquely identifies
|
|
it.
|
|
For example, when the X server reports a
|
|
.ZN GraphicsExpose
|
|
event to a client application, it sends an
|
|
.ZN XGraphicsExposeEvent
|
|
structure with the type member set to
|
|
.ZN GraphicsExpose .
|
|
The display member is set to a pointer to the display the event was read on.
|
|
The send_event member is set to
|
|
.ZN True
|
|
if the event came from a
|
|
.ZN 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.
|
|
.LP
|
|
The
|
|
.ZN XEvent
|
|
structure is a union of the individual structures declared for each event type:
|
|
.Ds 0
|
|
.TA .5i 3i
|
|
.ta .5i 3i
|
|
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;
|
|
.De
|
|
.LP
|
|
An
|
|
.ZN 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 always is send_event,
|
|
which is a
|
|
.ZN 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 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.
