    <title>Useful methods for a ButtonBox widget</title>
    <list>
      <item><p>The layout of the ButtonBox are set with <code>set_layout(layout)</code>, where <code>layout</code> can be <code>Gtk.ButtonBoxStyle.SPREAD</code> (buttons are evenly spread across the box), <code>Gtk.ButtonBoxStyle.EDGE</code> (buttons are placed at the edges of the box), <code>Gtk.ButtonBoxStyle.START</code> (buttons are grouped towards the start of the box), <code>Gtk.ButtonBoxStyle.END</code> (buttons are grouped towards the end of the box), <code>Gtk.ButtonBoxStyle.CENTER</code> (buttons are centered in the box).</p></item>
      <item><p><code>set_child_secondary(button, is_secondary)</code> sets whether <code>button</code> should appear in a secondary group of children. A typical use of a secondary child is the help button in a dialog. This group appears after the other children if the style is <code>START</code>, <code>SPREAD</code> or <code>EDGE</code>, and before the other children if the style is <code>END</code>. If the style is <code>START</code> or <code>END</code>, then the secondary children are aligned at the other end of the button box from the main children. For the other styles, they appear immediately next to the main children.</p></item>
      <item><p><code>set_child_non_homogeneous(button, is_non_homogeneous)</code> sets whether the child is exempted from homogeneous sizing. Default value is <code>False</code>.</p></item>
      <item><p><code>set_spacing(spacing)</code> sets the spacing, in pixels, between the buttons of the box.</p></item>
