+adjust its height on the fly as needed to accomodate the number of
+lines needed to display the current content of the control.  It is
+assumed that the width of the control will be a fixed value and
+that only the height will be adjusted automatically.  If the
+control is used in a sizer then the width should be set as part of
+the initial or min size of the control.
