"""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."""
