QTablewidget在列表节点上加入控件且实现上下移动

我的节点上加入了三个控件，上移，下移和删除

//信号链接部分

    connect(ui->btnUp,&QPushButton::clicked,this,&PollPlanTabOperator::onBtnMoveUpClicked);
    connect(ui->btnDown,&QPushButton::clicked,this,&PollPlanTabOperator::onBtnMoveDownClicked);
    connect(ui->btnDelete,&QPushButton::clicked,this,&PollPlanTabOperator::onBtnDeleteClicked);

//接受信号部分

void PollPlanTabOperator::onBtnMoveUpClicked()
{
    QModelIndex indexTemp = m_pollTaskTab->indexAt(QPoint(this->frameGeometry().x(),this->frameGeometry().y()));
    upAdownMoveRow(m_pollTaskTab,indexTemp.row(),indexTemp.row() - COUNT_ONE);

    //设置Up or Down按钮状态
    emit sigSetUpAndDownState();
}


void PollPlanTabOperator::onBtnMoveDownClicked()
{
    QModelIndex indexTemp = m_pollTaskTab->indexAt(QPoint(this->frameGeometry().x(),this->frameGeometry().y()));
    upAdownMoveRow(m_pollTaskTab,indexTemp.row(),indexTemp.row() + COUNT_TWO);

    //设置Up or Down按钮状态
    emit sigSetUpAndDownState();
}

void PollPlanTabOperator::onBtnDeleteClicked()
{
    QModelIndex indexTemp = m_pollTaskTab->indexAt(QPoint(this->frameGeometry().x(),this->frameGeometry().y()));
    m_pollTaskTab->removeRow(indexTemp.row());
    //重新排序
    updataSequence();
    //设置Up or Down按钮状态
    emit sigSetUpAndDownState();
}

//最主要的实现部分

void PollPlanTabOperator::upAdownMoveRow(QTableWidget *pTable,int currentRow,int toRow)
{
    if (pTable){
        int nRowCount = pTable->rowCount();
        int nColumnCount = pTable->columnCount();

        pTable->setFocus();

        if (currentRow != toRow){
            if (currentRow < COUNT_ZERO || toRow < COUNT_ZERO || currentRow > nRowCount || toRow > nRowCount)
                return;
            if (toRow < currentRow)
                currentRow ++;

            pTable->insertRow(toRow);

            for (int count = COUNT_ZERO;count < nColumnCount;count ++){
                if (count == TABLE_ROW_THREE){
                    PollPlanTabStopTimeLine *stopTimeLine = qobject_cast<PollPlanTabStopTimeLine *>(m_pollTaskTab->cellWidget(currentRow,count));
                    m_pollTaskTab->setCellWidget(toRow,count,stopTimeLine);
                }else if (count == TABLE_ROW_FOUR){
                    PollPlanTabOperator *tabOper = qobject_cast<PollPlanTabOperator *>(m_pollTaskTab->cellWidget(currentRow,count));
                    m_pollTaskTab->setCellWidget(toRow,count,tabOper);
                }else{
                    pTable->setItem(toRow,count,pTable->takeItem(currentRow,count));
                }
            }
            if (currentRow < toRow)
                toRow --;
            pTable->removeRow(currentRow);
            pTable->selectRow(toRow);
        }
    }
    //updataSequence();
}
