/* Paned Widgets
*
* The HPaned and VPaned Widgets divide their content
* area into two panes with a divider in between that the
* user can adjust. A separate child is placed into each
* pane.
*
* There are a number of options that can be set for each pane.
* This test contains both a horizontal (HPaned) and a vertical
* (VPaned) widget, and allows you to adjust the options for
* each side of each widget.
