如何将行号从QStringListModel分配给int对象

Question

我需要将所选行的数量（在on_listView_clicked中）分配给int变量。我试过int variable1 = index.row（）;但它不起作用。有人可以帮忙吗？

List_qt::List_qt(QWidget *parent)
        : QMainWindow(parent)
    {
        ui.setupUi(this);

        model = new QStringListModel(this);
        QStringList List;

        List << "Some Item1" << "Some Item2" << "Some Item3";

        model->setStringList(List)
        ui.listView->setModel(model);
    }


    void List_qt::on_listView_clicked(const QModelIndex &index)
    {

       int variable1 = index.row(); // this part of code can be compile but doesn't works after running application

    }
