/* Paned Widgets

 *

 * The GtkHPaned and GtkVPaned 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.
