The standard way to do this is to use the function
GtkFile.FileChooser.cast, which checks that your widget is really a
file chooser. Unfortunately, there seems to be a bug, and the returned
type is not correct (it contains only `filechooser, not `gtk and
`widget), so you will have to call also Gobject.unsafe_cast.

The whole command would look like

    let fcw = GtkFile.FileChooser.cast
       (Glade.get_widget ~name:"filechooserwidget" xmldata) in
    new GFile.chooser_widget (Gobject.unsafe_cast fcw)
