/* 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.
