Ok that looks much better,
however how should I create an overloaded class of a QApplication in my 
main dll class?
Since it is a library it normaly has no QApplication.

And If I try to derive from that
QMicosPolluxController::QMicosPolluxController(QWidget *parent)
    :   QWidget(parent)
    ,   QCoreApplication(1, "QMicosPolluxController")

I have to pass parameters, which I do not know, or at least the above is 
not ok.
"error: no matching function for call to 
'QCoreApplication::QCoreApplication(int, const char [23])'"
