XtAppAddActionHook(3)		 XT FUNCTIONS		 XtAppAddActionHook(3)

NAME
       XtAppAddActionHook, XtRemoveActionHook -	register an action hook	proce-
       dure

SYNTAX
       XtActionHookId XtAppAddActionHook(XtAppContext app_context, XtAction-
	      HookProc proc, XtPointer client_data);

       void XtRemoveActionHook(XtActionHookId id);

ARGUMENTS
       app_context
		 Specifies the application context.

       proc	 Specifies the action hook procedure.

       num_args	 Specifies the application-specific data to be passed to the
		 action	hook.

DESCRIPTION
       XtAppAddActionHook adds the specified procedure to the front of a list
       maintained in the application context. In the future, when an action
       routine is about	to be invoked for any widget in	this application con-
       text, either through the	translation manager or via XtCallActionProc,
       the action hohok	procedures will	be called in reverse order of regis-
       tration jut prior to invoking the action	routine.

       Action hook procedures are removed automatically	and the	XtActionHookId
       s destroyed when	the application	context	in which they were added is
       destroyed.

       XtRemoveActionHook removes the specified	action hook procedure from the
       list in which it	was registered.
