    <summary>A text entry field with a dropdown list</summary>
    <remarks>
      <para>
        The <see cref="T:Gtk.Combo" /> widget consists of a single-line text entry field and a
        drop-down list. The drop-down list is displayed when the user clicks
        on a small arrow button to the right of the entry field.
      </para>
      <para>
        The drop-down list is a <see cref="T:Glib.List" /> widget and can be accessed using the
        list member of the <see cref="T:Gtk.Combo" />. List elements can contain arbitrary
        widgets, but if an element is not a plain label, then you must use
        the <see cref="M:Glib.List.SetItemString()" /> function. This sets the string which
        will be placed in the text entry field when the item is selected.
      </para>
      <para>
        By default, the user can step through the items in the list using the
        arrow (cursor) keys, though this behaviour can be turned off with
        <see cref="P:Gtk.Combo.UseArrows" /> = <see langword="false" />.
      </para>
      <example>

          Creating a <see cref="T:Gtk.Combo" /> widget with simple text items:

	{
		new ComboSample ();	
	}
	
	ComboSample ()
	{
		Application.Init ();
	
		Window win = new Window ("ComboSample");
		win.DeleteEvent += new DeleteEventHandler (OnWinDelete);

		string[] list = new string[] {"one", "two", "three"};
		
		combo = new Combo ();
		combo.PopdownStrings = list;
		combo.DisableActivate ();
		combo.Entry.Activated += new EventHandler (OnEntryActivated);
		
		win.Add (combo);
	
		win.ShowAll ();
		Application.Run ();
	}
	
	void OnEntryActivated (object o, EventArgs args)
	{
		Console.WriteLine (combo.Entry.Text);
	}
	
	void OnWinDelete (object obj, DeleteEventArgs args)
	{
		Application.Quit ();
	}
