XtRemoveEventTypeHandler(3X)	 XT FUNCTIONS	  XtRemoveEventTypeHandler(3X)

NAME
       XtRemoveEventTypeHandler - extension event handling

SYNTAX
       void XtRemoveEventTypeHandler(widget, event_type, select_data, proc,
       client_data)
	     Widget widget;
	     int event_type;
	     XtPointer select_data;
	     XtEventHandler proc;
	     XtPointer client_data;

ARGUMENTS
       widget	 Specifies the widget for this event handler.  Must be of
		 class Core or any subclass thereof.

       event_type
		 Specifies the event type.

       select_data
		 Specifies data used to select or deselect events from the
		 server.

       proc	 Specifies the proc.

       client_data
		 Specifies additional data to be passed to the event handler.

DESCRIPTION
       The XtRemoveEventTypeHandler function unregisters an even handler reg‐
       istered with XtInsertEventTypeHandler for the specified event type. The
       request is ignored if client_data does not match the value given with
       the handler was registered.

       If event_type specifies on of the core X protocol events, select_data
       must be a pointer to a value of type EventMask, indicating the mask to
       be used to deselect for the appropriate event.  If the widget is real‐
       ized, XtRemoveEventTypeHandler calls XSelectInput if necessary. Speci‐
       fying NULL for select_data is equivalent to specifying a pointer to an
       event mask containing 0. This is similar to the XtRemoveRawEventHandler
       function.

       If event_type specifies an extension event type then the semantics of
       the data pointed to by select_data are defined by the extension selec‐
       tor registered for the specified event type.
