Fine. Is there any example/docs of it?

Sure, I am using the newest (v2 1.33) :)

I imagined that. But how should I do this? This base class is now on a 
shared library. You mean that the wrapper class (QObject_Wrapper) or the 
exposed class(class_<QObject_Wrapper>("Qobject")) should be in a separed 
shared library?

Anyway, Python modules are shared librarys anyway. But I think they don't 
see each other (modules).

No, the Windows dynamic linking system is different. However, the

Hmm, good. I really need someone to test things for me on Windows. I don't 
have a copy of it, besides it is "wild territory" for me.

Ok, let's get back to work :)
