    <desc>Un élément graphique qui affiche un menu quand il est cliqué</desc>
  </info>

  <title>MenuButton</title>
  <media type="image" mime="image/png" src="media/menubutton.png"/>
  <p>L'élément graphique GtkMenuButton sert à afficher un menu quand il est cliqué. Le menu peut provenir soit d'un GtkMenu, soit d'un GMenuModel abstrait. L'élément graphique GtkMenuButton peut contenir n'importe quel élément graphique enfant valide. Ceci dit, il peut contenir pratiquement n'importe quel autre GtkWidget standard. L'enfant le plus souvent utilisé est la flèche GtkArrow fournie.</p>

<note><p>Pour que le MenuButton fonctionne, il vous faut avoir installé GNOME 3.6</p></note>
