    <summary>A base class for the concrete slider widgets; <see cref="T:Gtk.HScale" /> and <see cref="T:Gtk.VScale" />.</summary>
    <remarks>
      <para>A Scale is a slider control used to select a numeric value. Specific manipulation can be done with methods and properties on its base class, <see cref="T:Gtk.Range" />. To set the value of a scale, you would normally use the <see cref="P:Gtk.Range.Value" /> property. To detect changes to the value, connect an event handler to the <see cref="F:Gtk.Range.ValueChanged" /> event.</para>
