lookup_default

function lookup_default(stock_id:String):Gtk.IconSet {
    // Gjs wrapper for gtk_icon_factory_lookup_default()
}

Looks for an icon in the list of default icon factories. For display to the user, you should use Gtk.lookup_icon_set on the Gtk.Style for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.
