QT如何获取ComboBox中选中的内容？

GoToCellDialog::GoToCellDialog(QWidget*parent):QDialog(parent)
{
   setupUi(this);
   connect(ComboBox,SIGNAL(activated(int)),this,SLOT(doSelectFont(int)));
}

 ComboBox = new QComboBox(groupBox);
        ComboBox->addItem(QObject::tr("/home/apuser/qt6"));
        ComboBox->addItem(QObject::tr("/home/apuser/qt1"));
