  <title>Barra de herramientas</title>
  <media type="image" mime="image/png" src="media/toolbar.png"/>
  <p>La barra de herramientas puede contener texto o iconos del almacén. En este ejemplo se usan iconos del almacén. Este ejemplo funciona a pantalla completa.</p>
  <p>Este ejemplo usa SimpleActions (ventana y aplicación). Las acciones de la aplicación se pueden añadir fácilmente al menú de la aplicación.</p>
