Problem with Qt plugin system

[fullmetalcoder]

This configuration doesn't work even if it respects pure interface and no-qobject-inheritance (on pkApplication) rules.

If I inherit ExampleApp directly from pkApplication everything works (obviously with some changes here and there).

Wow, you get the exact opposite of the expected behavior There must something weird with your project layout. Oh, by the way, would you mind defining "doesn't work", "everything work" and "some changes here and there", that might help us figuring out what's wrong.

Could you help me to find a solution for this problem, please?

Maybe but a more detailed explanation is needed (project layout, test you made, expected results, actual results and such...)
