    <summary>A container with just one child.</summary>
    <remarks>
      <para>
        A Bin widget is a <see cref="T:Gtk.Container" /> with just one
	child. It is used to create subclasses, since it provides
	common code needed for handling a single child <see cref="T:Gtk.Widget" />.
      </para>
      <para>
        Many GTK+ widgets are subclasses of Bin, including <see cref="T:Gtk.Window" />, <see cref="T:Gtk.Button" />, <see cref="T:Gtk.Frame" />, <see cref="T:Gtk.HandleBox" />, and
        <see cref="T:Gtk.ScrolledWindow" />.</para>
      <para>
        To place a child widget inside this container, use the
        standard <see cref="M:Gtk.Container.Add" /> method.</para>
      <para>
        For the widget to be useful, it should participate in size
        negotiation and size allocation using the events <see cref="E:Gtk.Widget.SizeAllocated" /> and <see cref="E:Gtk.Widget.SizeRequested" />.</para>
      <para>
        Sample follows.
      </para>
      <example>
        <code lang="C#">
using System;
using Gtk;
