[Qt-interest] Derive slots from non-Qt-based classes

Hmm.. yes, it's missing in SomeDerivedClass.
Q_OBJECT in SomeBaseClass is not allowed as it doesn't inherit from
QObject. And I really don't want to inherit from QObject! :-)

To make things more clear:
I want to extend QWidget based classes with additional methods.
Implementing the stuff in a subclass derived from QWidget works fine for
QWidgets but using the same additional stuff with a QGLWidget is not
possible.

I understand that I cannot call the slot in SomeBaseClass as this has
not been moc'ed, but I think it may be possible to use the parent code
in SomeDerivedClass, which actually is moc'ed.

Regards,
 Stefan
