Specifying NULL for \fIselect_data\fP is equivalent to +specifying a pointer to an event mask containing 0. This is similar to the +.ZN XtInsertRawEventHandler +function. +.LP +If \fIevent_type\fP specifies an extension event type then the semantics +of the data pointed to by \fIselect_data\fP are defined by the extension +selector registered for the specified event type. +.LP +In either case the Intrinsics are not required to copy the data pointed +to by \fIselect_data\fP, so the caller must ensure that it remains valid +as long as the event handler remains registered with this value of +\fIselect_data\fP. +.LP +The \fIposition\fP argument allows the client to control the order of the +invocation of event handlers registered for the same event type. If the +client does not care about the order, it should normally specify +.ZN XtListTail , +which registers this event handler after any previously registered +handlers for this event type. +.LP +The +.ZN XtRemoveEventTypeHandler +function unregisters an even handler registered with +.ZN XtInsertEventTypeHandler +for the specified event type. The request is ignored if \fIclient_data\fP +does not match the value given with the handler was registered. +.LP +If \fIevent_type\fP specifies on of the core X protocol events, +\fIselect_data\fP must be a pointer to a value of type +.ZN EventMask , +indicating the mask to be used to deselect for the appropriate event. +If the widget is realized, +.ZN XtRemoveEventTypeHandler +calls +.ZN XSelectInput +if necessary. Specifying NULL for \fIselect_data\fP is equivalent to +specifying a pointer to an event mask containing 0. This is similar to the +.ZN XtRemoveRawEventHandler +function. +.LP +If \fIevent_type\fP specifies an extension event type then the semantics +of the data pointed to by \fIselect_data\fP are defined by the extension +selector registered for the specified event type. +.LP +The +.ZN XtRegisterExtensionSelector +function registers a procedure to arrange for the delivery of extension +events to widgets. +.LP +If \fImin_event_type\fP and \fImax_event_type\fP match the parameters to +a previous call to +.ZN XtRegisterExtensionSelector +for the same display, the \fIproc\fP and \fIclient_data\fP replace the +previously registered values. If the range specified by \fImin_event_type\fP +and \fImax_event_type\fP overlaps the range of the parameters to a +previous call for the same display in any other way, an error results. +.LP +The +.ZN XtSetEventDispatcher +function registers the event dispatcher procedure specified by \fIproc\fP +for events with the type \fIevent_type\fP. The previously registered +dispatcher (or the default dispatcher if there was no previously registered +dispatcher) is returned. If \fIproc\fP is NULL, the default procedure is +restored for the specified type. +.LP +In the future, when +.ZN XtDispatchEvent +is called with an event of \fIevent_type\fP, the specified \fIproc\fP (or +the default dispatcher) will be invoked to determine a widget ot which +to dispatch the event. +.LP +The +.ZN XtDispatchEventToWidget +function scans the list of registered event handlers for the specified +widget and calls each handler that has been registered for the specified +event type, subject to the \fIcontinue_to_dispatch\fP value returned by +each handler. The Intrinsics behave as if event handlers were registered +at the head of the list for +.ZN Expose , +.ZN NoExpose , +.ZN GraphicsExpose , +and +.ZN VisibilityNotify +events to invoke the widget's expose procedure according to the exposure +compression rules and to update the widget's \fIvisible\fP field if +\fIvisible_interest\fP is +.ZN True . +These internal event handlers never set \fIcontinue_to_dispatch\fP to +.ZN False . +.LP +.ZN XtDispatchEventToWidget +returns +.ZN True +if any event handler was called and +.ZN False +otherwise. +.LP +.SH "SEE ALSO" +XtGetKeyboardFocusWidget(3Xt) +.br +\fI\*(xT\fP +.br +\fI\*(xL\fP -- cgit v1.2.3
