    <summary>A <see cref="T:Gtk.Container" /> that allows a scrollable view of its child when added to a <see cref="T:Gtk.ScrolledWindow" />.</summary>
    <remarks>
      <para>To scroll correctly, a <see cref="T:Gtk.ScrolledWindow" /> ordinarily requires explicit support from the <see cref="T:Gtk.Widget" /> that will be scrolled. However, a Viewport adds scrolling capabilities to an arbitrary child widget. For example, you can add a collection of widgets to a <see cref="T:Gtk.Table" /> container. By simply placing the <see cref="T:Gtk.Table" /> in a Viewport, you need only add the Viewport to a <see cref="T:Gtk.ScrolledWindow" /> to visually scroll the contents of your Table.</para>
      <para>The "model" of this widget consists of horizontal and vertical <see cref="T:Gtk.Adjustment" /> objects. These do not need to be explicitly set to use the Viewport. Packing a child widget as demonstrated in the example, below, is all that is required.</para>
      <para>The appearance of the Viewport can be adjusted using the <see cref="P:Gtk.Viewport.ShadowType" /> property.</para>
      <para>The following example creates a <see cref="T:Gtk.Table" /> in a Viewport. When placed in a small <see cref="T:Gtk.Window" />, the widgets can be scrolled.
