  <media type="image" mime="image/png" src="media/toolbar.png"/>
  <p>La barre d'outils peut contenir soit du texte, soit des icônes de la collection. Dans cet exemple, nous utilisons les icônes de la collection. Cet exemple possède la fonction plein écran.</p>
  <p>Cet exemple utilise SimpleActions (fenêtre et application). Les actions applications peuvent être facilement ajoutées au menu « Applications ».</p>
