# Barre d'outils

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.

Cet exemple utilise SimpleActions (fenêtre et application). Les actions applications peuvent être facilement ajoutées au menu « Applications ».

const Gdk = imports.gi.Gdk; const Gio = imports.gi.Gio; const GLib = imports.gi.GLib; const Gtk = imports.gi.Gtk; const Lang = imports.lang;
