    if (QStyleOptionProgressBarV2 *optionV2
            = qstyleoption_cast<QStyleOptionProgressBarV2 *>(option)) {
        optionV2->orientation = d->orientation;  // ### Qt 5: use State_Horizontal instead
        optionV2->invertedAppearance = d->invertedAppearance;
        optionV2->bottomToTop = (d->textDirection == QProgressBar::BottomToTop);
    }
