首先是向tableview中添加内容

model=new QStandardItemModel();    model->setHorizontalHeaderItem(0, new QStandardItem(QObject::tr("id")));    //model->setHorizontalHeaderItem(1, new QStandardItem(QObject::tr("场馆编号")));    model->setHorizontalHeaderItem(1, new QStandardItem(QObject::tr("昵称")));    //QList
     
       tmplist;    //model->insertRow(0,tmplist);    //ui->order->setModel(model);    ui->tableView->setModel(model);    ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);    ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);    QSqlQuery query;    QString sql="select * from tuser";    if(!query.exec(sql)){        QMessageBox::warning(this,"error","连接失败");        this->close();    }    QList
      
        list;    int t=0;    while(query.next())    {        qDebug()<
       
        setItem(t,0,id);        model->setItem(t++,1,name);    }
       
      
     

然后是获取某一选中行的信息

int row=ui->tableView->currentIndex().row();    if(row<0){        QMessageBox::warning(this,"error","请先选中某条订单",QMessageBox::Yes);        return;    }    //弹出确认删除信息消息框    QMessageBox *del;    QString mes="";    mes=model->item(row,0)->data(Qt::DisplayRole).toString();    mes=value+model->item(row,1)->data(Qt::DisplayRole).toString();

 获取cell中的内容

QStandardItem * QStandardItemModel::item ( int row, int column = 0 ) constmodel->item(row, column)->text()就得到了文本内容。QTableWidget 约等于 QTableView + Model
