XtCallActionProc(3Xt)						   XT FUNCTIONS 					     XtCallActionProc(3Xt)

NAME

       XtCallActionProc - invoke an action procedure directly

SYNTAX

       void XtCallActionProc(Widget widget, String action, XEvent* event, String* params, Cardinal num_params);

ARGUMENTS

       widget	 Specifies the widget in which the action is to be invoked. Must be of class core of any subclass thereof.

       action	 Specifies the name of the action routine.

       event	 Specifies the contents of the event passed to the action routine.

       params	 Specifies the contents of the params passed to the action routine.

       num_params
		 Specifies the num of entries in params.

DESCRIPTION

       XtCallActionProc searches for the named action routine in the same manner and order as translation tables are bound. If found, the action
       routine is invoked with the specified widget, event pointer, and parameters. It is the responsibility of the caller to ensure that the con-
       tents of event, params, and num_params arguments are appropriate for the specified routine, and if necessary, that the specified widget is
       realized or sensitive. If the named action routine cannot be found, XtCallActionProc generates a warning message and returns.

XtAppAddActionHook(3Xt) 					   XT FUNCTIONS 					   XtAppAddActionHook(3Xt)

NAME

       XtAppAddActionHook, XtRemoveActionHook - register an action hook procedure

SYNTAX

       XtActionHookId XtAppAddActionHook(app_context, proc, client_data)
	     XtAppContext app_context;
	     XtActionHookProc proc;
	     XtPointer client_data;

       void XtRemoveActionHook(id)
	     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 context, either through the translation manager or via XtCallActionProc,
       the action hohok procedures will be called in reverse order of registration 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.
