Hi Jacques,

OK, then consider my message a request for a high-level interface
to them :)

I must say I have no idea why this cast makes any sense. As far as I
can tell, the type of [model#as_model] is Gtk.tree_model, which is
declared as a synonym for [`treemodel] Gtk.obj. (By the way, are
[Gtk.obj] and [Gobject.obj] the same type? This is confusing.)
Why is it legal to cast it up to Gtk.tree_model Gtk.obj? The answer
is beyond me. This is a point that I would very much like to understand.

It doesn't seem to be available in GtkWindow.Window, at least not in the
20030828 snapshot.

Are all of them currently available at the low level? (I mean, can I,
in principle, access every GTK feature without modifying LablGTK?)
