Hi

I'm trying to create dll and link with simple Qt application.
It looks that I have created dll in good way.
I has extern "C" and definition for import export of classes and functions in dll.
Is very any good tutorial how to make dll in qt and use with new Qt application?
I have found some examples in Internet but I would like to see good example of let's say dll with one object and application which uses this object.
Do you know any good tutorials about it?

Regards,
Pawel
