QTableView右键删除功能实现

ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);
ui->tableView->setContextMenuPolicy(Qt::CustomContextMenu);

 

m_rightClickMenu = new QMenu(this);               //右键点击菜单
    auto deleteAction = new QAction(tr("删除"), this);               //删除事件
    m_rightClickMenu->addAction(deleteAction);    //将action添加到菜单内

    connect(ui->tableView, SIGNAL(customContextMenuRequested(QPoint)), this, SLOT(SLot_Measure_Table_Click_Ritht_Menu(QPoint)));

connect(deleteAction,&QAction::triggered,this,[=]()
    {
        QList<int> rows;
        QItemSelection selection = ui->tableView->selectionModel()->selection();
        for (const QItemSelectionRange &selectionRange : selection)
        {
            for (int row = selectionRange.top(); row <= selectionRange.bottom(); ++row)
                rows.append(row);
        }
        qSort(rows.begin(), rows.end(), qGreater<int>());
        for (int row : rows)
            m_model->removeRow(row);
    });

//表格菜单  数据 更新
void MainWidget::SLot_Measure_Table_Click_Ritht_Menu(QPoint pos)
{
    QModelIndex index = ui->tableView->indexAt(pos);    //找到tableview当前位置信息
    if (index.isValid())        //如果行数有效，则显示菜单
    {
        m_rightClickMenu->exec(QCursor::pos());
    }
