     DESCRIPTION
	  The XtSetValues function starts with the resources specified
	  for the Core widget fields and proceeds down the subclass
	  chain to the widget.	At each stage, it writes the new value
	  (if specified by one of the arguments) or the existing value
	  (if no new value is specified) to a new widget data record.
	  XtSetValues then calls the set_values procedures for the
	  widget in superclass-to-subclass order.  If the widget has
	  any non-NULL set_values_hook fields, these are called
	  immediately after the corresponding set_values procedure.
	  This procedure permits subclasses to set nonwidget data for
	  XtSetValues.

	  If the widget's parent is a subclass of
	  constraintWidgetClass, XtSetValues also updates the widget's
	  constraints.	It starts with the constraint resources
	  specified for constraintWidgetClass and proceeds down the
	  subclass chain to the parent's class.	 At each stage, it
	  writes the new value or the existing value to a new
	  constraint record.  It then calls the constraint set_values
	  procedures from constraintWidgetClass down to the parent's
	  class.  The constraint set_values procedures are called with
	  widget arguments, as for all set_values procedures, not just
	  the constraint record arguments, so that they can make
	  adjustments to the desired values based on full information
	  about the widget.

	  XtSetValues determines if a geometry request is needed by

     Page 2					     (printed 7/20/06)

     XtSetValues(3Xt)	X Version 11 (Release 6.6)    XtSetValues(3Xt)

	  comparing the current widget to the new widget.  If any
	  geometry changes are required, it makes the request, and the
	  geometry manager returns XtGeometryYes, XtGeometryAlmost, or
	  XtGeometryNo.	 If XtGeometryYes, XtSetValues calls the
	  widget's resize procedure.  If XtGeometryNo, XtSetValues
	  resets the geometry fields to their original values.	If
	  XtGeometryAlmost, XtSetValues calls the set_values_almost
	  procedure, which determines what should be done and writes
	  new values for the geometry fields into the new widget.
	  XtSetValues then repeats this process, deciding once more
	  whether the geometry manager should be called.

	  Finally, if any of the set_values procedures returned True,
	  XtSetValues causes the widget's expose procedure to be
	  invoked by calling the Xlib XClearArea function on the
	  widget's window.

	  The XtSetSubvalues function stores resources into the
	  structure identified by base.

	  The XtGetValues function starts with the resources specified
	  for the core widget fields and proceeds down the subclass
	  chain to the widget.	The value field of a passed argument
	  list should contain the address into which to store the
	  corresponding resource value.	 It is the caller's
	  responsibility to allocate and deallocate this storage
	  according to the size of the resource representation type
	  used within the widget.

	  If the widget's parent is a subclass of
	  constraintWidgetClass, XtGetValues then fetches the values
	  for any constraint resources requested.  It starts with the
	  constraint resources specified for constraintWidgetClass and
	  proceeds down to the subclass chain to the parent's
	  constraint resources.	 If the argument list contains a
	  resource name that is not found in any of the resource lists
	  searched, the value at the corresponding address is not
	  modified.  Finally, if the get_values_hook procedures are
	  non-NULL, they are called in superclass-to-subclass order
	  after all the resource values have been fetched by
	  XtGetValues.	This permits a subclass to provide nonwidget
	  resource data to XtGetValues.

	  The XtGetSubvalues function obtains resource values from the
	  structure identified by base.
