Hi!

OK, I should have RTFM! Anyway, if I add a call to add_interface() in
the constructor I don't get the casting critical but the program crashes
because it does not find my implementation of the interface.

Looking through the Gtkmm source code I have seen that all interfaces
have WRAP_METHOD and WRAP_VFUNC for all functions. Is this the correct
way to do it?

Regards,
Johannes
