Qtablevies获取内容

首先是向tableview中添加内容

 model=new QStandardItemModel();
    model->setHorizontalHeaderItem(, new QStandardItem(QObject::tr("id")));
    //model->setHorizontalHeaderItem(1, new QStandardItem(QObject::tr("场馆编号")));
    model->setHorizontalHeaderItem(, new QStandardItem(QObject::tr("昵称")));

    //QList<QStandardItem*> 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<QStandardItem*> list;
    int t=;
    while(query.next())
    {
        qDebug()<<query.value().toString();
        QStandardItem *id=new QStandardItem(query.value().toString());
        QStandardItem *name=new QStandardItem(query.value().toString());
        model->setItem(t,,id);
        model->setItem(t++,,name);

    }

然后是获取某一选中行的信息

int row=ui->tableView->currentIndex().row();
    if(row<){
        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,)->data(Qt::DisplayRole).toString();
    mes=value+model->item(row,)->data(Qt::DisplayRole).toString();

获取cell中的内容

QStandardItem * QStandardItemModel::item ( int row, int column =  ) const

model->item(row, column)->text()就得到了文本内容。

QTableWidget 约等于 QTableView + Model
