RibbonGroup添加QRadioButton：

QRadioButton * pRadio = new QRadioButton(tr("Radio"));
             pRadio->setToolTip(tr("Radio"));
             groupClipboard->addWidget(pRadio);
             connect(pRadio, SIGNAL(clicked(bool)), this, SLOT(RadioClicked(bool)));

添加事件：

protected slots:
     void RadioClicked(bool checked = false);void QRibbonDemo::RadioClicked(bool checked)
 {
     QMessageBox messageBox(QMessageBox::Information, windowTitle(),
         QLatin1String(""), QMessageBox::Ok, this);
     messageBox.setInformativeText(QLatin1String("radio click."));
     messageBox.exec();
 }

效果如下：
