QT 实现tablewidget整行的上下移动和双击编辑

一、效果展示

二、实现方法
1、先对tablewidget设置

    this->ui->tableWidget->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);
    this->ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);  //单击选择行
    this->ui->tableWidget->setSelectionMode(QAbstractItemView::SingleSelection); //设置只能选择一行
    this->ui->tableWidget->setEditTriggers(QAbstractItemView::DoubleClicked);   //设置内容不可更改
    this->ui->tableWidget->setAlternatingRowColors(true);                        //设置隔行改变颜色
    this->ui->tableWidget->verticalHeader()->setVisible(true);                  //显示行号
    this->ui->tableWidget->setTextElideMode(Qt::ElideMiddle);

    this->ui->tableWidget->setColumnCount(peopleItemMax);
    this->ui->tableWidget->setRowCount(0);
    this->ui->tableWidget->setHorizontalHeaderLabels(QStringList()<<tr("人员名称")<<tr("等待时间(分钟)")<<tr("开始时间")<<tr("结束时间"));
    this->ui->tableWidget->setContextMenuPolicy(Qt::CustomContextMenu);
    this->ui->tableWidget->setSelectionMode(QAbstractItemView::SingleSelection);

2、实现行的上下移动
主要实现方式是通过交换两行的数据来实现的

   QString currItemNumber = ui->tableWidget->item(currSelectRow,orderItemNumber)->text();//合同编号
    QString currItemProductName = ui->tableWidget->item(currSelectRow,orderItemProductName)->text();//零件名称
    QString currItemProductNo = ui->tableWidget->item(currSelectRow,orderItemProductNo)->text();//零件编号
    QString currItemDrawingNo = ui->tableWidget->item(currSelectRow,orderItemDrawingNo)->text();//图纸图号
    QString currItemMaterial = ui->tableWidget->item(currSelectRow,orderItemMaterial)->text();//材质
    QString currItemQuantity = ui->tableWidget->item(currSelectRow,orderItemQuantity)->text();//数量
    QString currItemWorkTime = ui->tableWidget->item(currSelectRow,orderItemWorkTime)->text();;    //工作时间
    QDate currItemDeliveryDate= ((QDateEdit *)ui->tableWidget->cellWidget(currSelectRow,orderItemDeliveryDate))->date();    //交期
    QString currItemRemarks = ui->tableWidget->item(currSelectRow,orderItemRemarks)->text();//备注


    ui->tableWidget->item(currSelectRow,orderItemNumber)->setText(ui->tableWidget->item(moveRow,orderItemNumber)->text());//合同编号
    ui->tableWidget->item(currSelectRow,orderItemProductName)->setText(ui->tableWidget->item(moveRow,orderItemProductName)->text());//零件名称
    ui->tableWidget->item(currSelectRow,orderItemProductNo)->setText(ui->tableWidget->item(moveRow,orderItemProductNo)->text());//零件编号
    ui->tableWidget->item(currSelectRow,orderItemDrawingNo)->setText(ui->tableWidget->item(moveRow,orderItemDrawingNo)->text());//图纸编号
    ui->tableWidget->item(currSelectRow,orderItemMaterial)->setText(ui->tableWidget->item(moveRow,orderItemMaterial)->text());//材质
    ui->tableWidget->item(currSelectRow,orderItemQuantity)->setText(ui->tableWidget->item(moveRow,orderItemQuantity)->text());//数量
    ui->tableWidget->item(currSelectRow,orderItemWorkTime)->setText(ui->tableWidget->item(moveRow,orderItemWorkTime)->text());//工作时间

    ((QDateEdit *)ui->tableWidget->cellWidget(currSelectRow,orderItemDeliveryDate))//交期
            ->setDate(((QDateEdit *)ui->tableWidget->cellWidget(moveRow,orderItemDeliveryDate))->date());
    ui->tableWidget->item(currSelectRow,orderItemRemarks)->setText(ui->tableWidget->item(moveRow,orderItemRemarks)->text());//备注

    ui->tableWidget->item(moveRow,orderItemNumber)->setText(currItemNumber);//合同编号
    ui->tableWidget->item(moveRow,orderItemProductName)->setText(currItemProductName);//零件名称
    ui->tableWidget->item(moveRow,orderItemProductNo)->setText(currItemProductNo);//零件编号
    ui->tableWidget->item(moveRow,orderItemDrawingNo)->setText(currItemDrawingNo);//图纸编号
    ui->tableWidget->item(moveRow,orderItemMaterial)->setText(currItemMaterial);//材质
    ui->tableWidget->item(moveRow,orderItemQuantity)->setText(currItemQuantity);//数量
    ui->tableWidget->item(moveRow,orderItemWorkTime)->setText(currItemWorkTime);//工作时间
    ((QDateEdit *)ui->tableWidget->cellWidget(moveRow,orderItemDeliveryDate))->setDate(currItemDeliveryDate);//开始时间
    ui->tableWidget->item(moveRow,orderItemRemarks)->setText(currItemRemarks);//备注
    //列表模型和表格模型的所有数据项都是以根项为父项的,用QModelIndex()表示父项
    QModelIndex index = ui->tableWidget->model()->index(moveRow, orderItemNumber, QModelIndex());

    ui->tableWidget->setCurrentIndex(index);

下面这两句主要实现选择行跟随移动的行

    QModelIndex index = ui->tableWidget->model()->index(moveRow, orderItemNumber, QModelIndex());

    ui->tableWidget->setCurrentIndex(index);
