  <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>You need to be running GNOME 3.6 or later for the MenuButton to work.</p></note>
