Thanks - I figured it out now with your mails. Here's how I ended up
doing it (code somewhat simplified):
Glib::RefPtr<Gdk::Pixbuf> icon_pixbuf = _mypic.get_pixbuf();
Glib::RefPtr<Gdk::Pixbuf> chosen_icon_pb
= Gdk::Pixbuf::create_subpixbuf(icon_pixbuf, 0, 0, 32, 32);
_icon = new Gtk::Image(chosen_icon_pb);
Cheers,
Andreas.
