Sorry, I've mistaken stub for skeleton.

What I wrote above is for the skeleton and what I wrote below is the stub.

Yeah, it's the stub.

I'm aiming at not needing the _stub.cpp file. Move all the code to the .h 
file and install it. As long as nothing is virtual in this stub, there 
won't be a need to make it belong to one given library.

See the other email. This is not likely to happen. You'll derive from 
QObject now.
