/* Paned Widgets
*
* The GtkPaned Widget divides its content area into two panes
* with a divider in between that the user can adjust. A separate
* child is placed into each pane. GtkPaned widgets can be split
* horizontally or vertially.
*
* There are a number of options that can be set for each pane.
* This test contains both a horizontal and a vertical GtkPaned
* widget, and allows you to adjust the options for each side of
* each widget.
