catch signal stepDown from doubleSpinBox

[caduel]

That should not be the case. Can you show us you .pro file, and the complete header file?

Now I tried to subclass from doubleSpinBox again. It works now (new project, dont know why it failed in the old one).

However the slot:
void QScienceSpinBox::stepDown()

is never called if I press up or down arrows.

The code is looking like this:

class QScienceSpinBox : public QDoubleSpinBox
{
Q_OBJECT
public:
    QScienceSpinBox(QWidget * parent = 0);
 
    QString textFromValue ( double value ) const;
    double valueFromText ( const QString & text ) const;
...	
private slots:
	void stepDown();
	void stepUp();
 
};

class QScienceSpinBox : public QDoubleSpinBox
{
Q_OBJECT
public:
    QScienceSpinBox(QWidget * parent = 0);

    QString textFromValue ( double value ) const;
    double valueFromText ( const QString & text ) const;
...	
private slots:
	void stepDown();
	void stepUp();

};

Is it only the stepDown slot? The stepUp/Down slots are public in QDoubleSpinBox, and you are redeclaring them as private. Maybe that's causing your problem.

makeing the slots public changes nothing. The functions are still not called at button up or down.

EDIT:
If I use the correct virtual function it works:

// overwritten virtual function of QAbstractSpinBox
void QScienceSpinBox::stepBy(int steps)
{
	if (steps < 0)
		stepDown();
	else
		stepUp();
}
 
void QScienceSpinBox::stepDown()
{
	QSBDEBUG() << "stepDown()";
	setValue(value()/10.0);
}
 
void QScienceSpinBox::stepUp()
{
	QSBDEBUG() << "stepUp()";
	setValue(value()*10.0);
}

// overwritten virtual function of QAbstractSpinBox
void QScienceSpinBox::stepBy(int steps)
{
	if (steps < 0)
		stepDown();
	else
		stepUp();
}

void QScienceSpinBox::stepDown()
{
	QSBDEBUG() << "stepDown()";
	setValue(value()/10.0);
}

void QScienceSpinBox::stepUp()
{
	QSBDEBUG() << "stepUp()";
	setValue(value()*10.0);
}
