set_values_hook()														 set_values_hook()

Name
  set_values_hook - obsolete Object method for handling changes to subpart resources.

Synopsis
  typedef Boolean (*XtArgsFunc)(Widget, ArgList, Cardinal *);
	 Widget w;
	 ArgList args;
	 Cardinal *num_args;

Inputs
  w	    Specifies the widget whose nonwidget resource values are to be changed.

  args	    Specifies the argument list that was passed to XtSetValues().

  num_args  Specifies the number of arguments in the argument list.

Returns
  True if the widget should be redrawn; False otherwise.

Availability
  Obsolete in Release 4 and later.

Description
  The set_values_hook() method is registered on the set_values_hook field of the Object, RectObj, or Core class part structure.  It is called
  by XtSetValues() after the class's set_values() method has been called.

  As of Release 4, the set_values_hook() method is obsolete, because the args and num_args arguments  are  now	passed	to  the  set_values()
  method.   Its  purpose  had  been to allow the value of subpart resources to be set from the argument list, by calling XtSetSubvalues() for
  example.

  The arguments to the set_values_hook() method are the widget and the argument list that were passed to XtSetValues().  The widget will have
  been	modified  by  any  superclass  methods	that have already been called.	It should return True if the change to subpart resources will
  require the widget to be redraw, and False otherwise.

  The set_values_hook() method is chained in superclass-to-subclass order and is called for compatibility with older widgets.  It  cannot  be
  inherited,  and  any new widget classes should set their set_values_hook field to NULL.  See XtSetValues(1) for details on when this method
  is called.  See set_values(4) for a discussion of setting the values of subpart resources, and other resources that do not  appear  on  the
  class resource list.
