QSlider: emitting a signal with different parameter type

[mastupristi]

I have a QSlider, and I need a double value.

I have MySlider based on QSlider

class MySlider : public QSlider
{
    Q_OBJECT
public:
    MySlider();
signals:
    void valueChanged ( double );
};

class MySlider : public QSlider
{
    Q_OBJECT
public:
    MySlider();
signals:
    void valueChanged ( double );
};

To copy to clipboard, switch view to plain text mode 

How can I connect valueChanged(int); to my valueChanged(double);? All Example I found never implement a signal.

thanks
