[Qt-interest] Howot reimplement stepDown()/stepUp() from QDoubleSpinBox

[Matthias Pospiech]

I have a class QScienceSpinBox, derived from QDoubleSpinBox.

class QScienceSpinBox : public QDoubleSpinBox

within this class I declare the slots

public slots:
    void stepDown();
    void stepUp();


However when I use the up and down Buttons these slots are never entered.
How would I achieve hat?
