    You can use a QProxyStyle.
    First time is a bit WTF so here an example.

    class CustomTabStyle : public QProxyStyle {
      QSize sizeFromContents(ContentsType type, const QStyleOption* option,
                             const QSize& size, const QWidget* widget) const {
        QSize s = QProxyStyle::sizeFromContents(type, option, size, widget);
        if (type == QStyle::CT_TabBarTab) {
        return s;
      void drawControl(ControlElement element, const QStyleOption* option, QPainter* painter, const QWidget* widget) const {
        if (element == CE_TabBarTabLabel) {
          if (const QStyleOptionTab* tab = qstyleoption_cast<const QStyleOptionTab*>(option)) {
            QStyleOptionTab opt(*tab);
            opt.shape = QTabBar::RoundedNorth;
            QProxyStyle::drawControl(element, &opt, painter, widget);
        QProxyStyle::drawControl(element, option, painter, widget);

    and set it
    ui->tabWidget->tabBar()->setStyle(new CustomTabStyle);
