Override next button functionality in QWizardPage

[Carlavilla]

Hi,

I want to make some things when the next or back button are pressed in a QWizardPage.
But I don't know how to override the functionality of that buttons.

I saw in the Qt Documentation page the function nextId: https://doc.qt.io/qt-5/qwizard.html#nextId
But that's only for indicate the order page in non-linear wizards.

Some suggestion?

Thanks

Unless someone knows a better way, could you handle the QWizard::currentIdChanged(int id) signal?

Or, if you have derived your own class from base QWizard (always a good idea), you can just override QWizard::next() --- maybe do your own stuff, then call base QWizard::next(), depending on what you want to do?

I've done this:

This is my header file:

class MachineNamePage: public QWizardPage {
    Q_OBJECT

    public:
        ......
    signals:
       ......
    public slots:
        void selectOS(int OSSelected);
        void next();

    protected:

    private:
        ......
};

This is my source file:

MachineNamePage::MachineNamePage(QWidget *parent) : QWizardPage(parent) {
......
}

void MachineNamePage::next() {
    qDebug() << "Next";
}

But I don't know how to make the QWizardPage execute the code inside MachineNamePage::next()

I solve the problem using the 'validatePage' function.

bool MachineNamePage::validatePage() {

    return true;
}
