Exactly. The key here is to *not* inherit QDialog to implement the dialog m=
ain=20
contents, but to compose those two parts from one class that implements the=
=20
dialog interface (for consistency) and another set of classes that implemen=
t=20
the different dialog types. That is why the whole janus widget idea is wron=
g.=20
It is possible to do this, but this does not mean it makes sense.=20

I again suggest the get rid of the janus widget idea and use a dialog base=
=20
class and different dialog view classes. We have to come up with a nice ter=
m=20
in lieu of view, as Qt has successfully occupied ~View for item view=20
implementations (no problem with that, though).

Best regards,
