    <title>Useful methods for a Paned widget</title>
    <p>To have two vertically aligned panes, use <code>Gtk.Orientation.VERTICAL</code> instead of <code>Gtk.Orientation.HORIZONTAL</code>. The method <code>add1(widget1)</code> will add the <code>widget1</code> to the top pane, and <code>add2(widget2)</code> will add the <code>widget2</code> to the bottom pane.</p>
