How to disable NextButton in QWizard ?

[litroncn]

Thanks a million, It solved my problem, i did the following:

bool QWizardPage::isComplete()const
{
    if (startPushButton->isEnabled()) {
    return false;
    } else {
    return true;
    }
}

bool QWizardPage::isComplete()const
{
    if (startPushButton->isEnabled()) {
    return false;
    } else {
    return true;
    }
}

To copy to clipboard, switch view to plain text mode 

I am puzzled why I can't disable the QWizard's NextButton in QWizardPage::initializePage(). I did the following:

QAbstractButton *button = wizard()->button(QWizard::NextButton);
button->setEnabled(false);

QAbstractButton *button = wizard()->button(QWizard::NextButton);
button->setEnabled(false);

If you have any suggestions why this is the case, I'd be interested to hear the reason!
Any help would be appreciated!
