  I guess the main thing that confuses me here is that I can't see the
signal, even in 004.  Is it something you haven't added yet?

  The way that I would expose a read-only slot in sigc++ is to pass a
slot object into an (abstract) method, e.g.:

    virtual sigc::connection connect_tab_changed(const
sigc::slot<void, tab *> &slot) = 0;

  If Qt has no way of abstracting over slots, that would make this
difficult.  In that case maybe you could just make a public signal for
now?
