How can I overwrite the "next" slot in a QWizard?

Question

I'm using a QWizard class, which contains several QWizardPage. For some pages, I need to do something when the "Next" button is clicked.

I tried to overwrite the next slot in my QWizard class; however, it seems this doesn't work. The program still went into the original next slot in the parent QWizard class instead of the one I implemented.

Is this because this next slot is virtual protected? How can I do some things after the next button is clicked?

The header file of my QWizard class follows. By the way, the accept signal works fine as what I expected.

#ifndef PRIMERWIZARD_H
#define PRIMERWIZARD_H

#include <QWizard>

namespace Ui {
    class PrimerWizard;
}

class PrimerWizard : public QWizard {
    Q_OBJECT
public:
    PrimerWizard(QWidget *parent = 0);
    ~PrimerWizard();
protected slots:
    void next();
    void accept();

protected:
    void changeEvent(QEvent *e);

private:
    Ui::PrimerWizard *ui;
};

#endif // PRIMERWIZARD_H

I create a new wizard instance via QtCreator's wizard (Ha XD)

The code is as follows:

PrimerWizard* pW = new PrimerWizard(this);
pW->exec();

And the signal-slot connection of next is created by QtCreator, I cannot find where it's actually connected. I think the connection is built in ui_PrimerWizard.h by this function:

QMetaObject::connectSlotsByName(PrimerWizard);

The next slot cannot be overwritten. However, the validatePage function for QWizardPage can. This function will be called when the "Next" or "Finish" button is clicked.
