    <summary>A widget used to choose from a list of valid choices.</summary>
    <remarks>
      <para>
		A <see cref="T:Gtk.OptionMenu" /> is a widget that allows the user to choose from a list of valid choices.
		The <see cref="T:Gtk.OptionMenu" /> displays the selected choice.
		When activated the <see cref="T:Gtk.OptionMenu" /> displays a popup <see cref="T:Gtk.Menu" /> which allows the user to make a new choice.    
	  </para>
      <para>
	    Using a <see cref="T:Gtk.OptionMenu" /> is simple; build a <see cref="T:Gtk.Menu" />, by calling <see cref="C:Gtk.Menu()" />, then appending <see cref="T:Gtk.MenuItem" />s to it with <see cref="M:Gtk.MenuShell.Append()" />.
		Set that menu on the <see cref="T:Gtk.OptionMenu" /> with <see cref="P:Gtk.OptionMenu.Menu" />.
		Set the selected <see cref="T:Gtk.MenuItem" /> with <see cref="M:Gtk.OptionMenu.SetHistory(System.UInt32)" />; connect to the event <see cref="E:Gtk.OptionMenu.Changed" />; when the <see cref="E:Gtk.OptionMenu.Changed" /> event occurs, check the new selected <see cref="T:Gtk.MenuItem" /> with <see cref="P:Gtk.OptionMenu.History" />.

      <code language="C#">

using Gtk;

		MenuItem miTwo = new MenuItem ("Two");
		m.Append (miTwo);
		MenuItem miThree = new MenuItem ("Three");
		m.Append (miThree);
		
		// add children widgets to their parents
		opt.Menu = m;
		win.Add (opt);
		
		
		// set the OptionMenu to a value
