实际项目中，group中需要添加按钮与点击事件：

添加实例如下：

if (Qtitan::RibbonGroup* groupClipboard = pageHome->addGroup(tr("Clipboard")))
         {
             //右下角按钮显示
             groupClipboard->setOptionButtonVisible();
             QAction* act = groupClipboard->getOptionButtonAction();
             act->setText(tr("Clipboard"));
             act->setToolTip(tr("Show the Office clipboard Task Pane"));
             act->setStatusTip(tr("Show the Office clipboard Task Pane"));
             connect(act, SIGNAL(triggered()), this, SLOT(optionClipboard()));            QAction*  pactionPaste = groupClipboard->addAction(QIcon(":/QRibbonDemo/res/largeThemes.png"),
                 tr("&Paste"), Qt::ToolButtonTextUnderIcon);
             pactionPaste->setToolTip(tr("Paste Click"));
             connect(pactionPaste, SIGNAL(triggered()), this, SLOT(optionPaste()));
         }

响应事件：

protected slots:
     void optionPaste();void QRibbonDemo::optionPaste()
 {
     QMessageBox messageBox(QMessageBox::Information, windowTitle(),
         QLatin1String(""), QMessageBox::Ok, this);
     messageBox.setInformativeText(QLatin1String("Paste"));
     messageBox.exec();
 }

RibbonGroup添加QAction_ToolButton

效果如下所示：
