从文本数据中读取并在 QTableView 中显示

Question

我不知道.. 例如，我会有一个文本数据：

名称、值

汉斯，13 岁

彼得，30

我不知道我是怎么读的。。谁能帮帮我？

QString fileName;
fileName = QFileDialog::getOpenFileName(this, tr("Datei Oeffnen"),"",
                                            "Alle Dateien (*.txt)");
//QString in QFile
    QFile file (fileName);

//Status ob File gelesen werden kann

if (file.open(QIODevice::ReadOnly | QIODevice::Text))
{
    QMessageBox::information(this, tr("ERROR"), tr("Daten konnten icht eingelesen werden"));
    return;
}
QTextStream stream (&file);
       
while (!file.atEnd())
{
      QString line = stream.readLine();
      QStringList list = line.split(",");
      //dont know, because i woult have 2 Strings. because i would add it in my 
      // Model  : meinModel->setData(firstString,secondString);

}

这是我模型的setData 方法：

bool Model::setData(QString name,QString value )
{
    beginInsertRows(QModelIndex(), names.size(), names.size());
    names.push_back(name);
    values.push_back(value);
    endInsertRows();
    qDebug() << "inhalt name:"<< name;
    qDebug() << "inhalt value:"<< name;

    std::cout << names.size() << std::endl;
    QModelIndex topLeft = createIndex(0,0);
    QModelIndex bottomRights = createIndex(names.size()-1,1);
     //emit a signal to make the view reread identified data
    emit dataChanged(topLeft, bottomRights);
    return true;
}

我认为这是非常困难的解决方案，我做得更容易。我的代码 sn-p 可以按您的意愿工作，在评论中我也会向您展示您的错误。

QStandardItemModel *model = new QStandardItemModel(this);


QString fileName;
//QString in QFile
    QFile fileMy ("G:\\2\\fil.txt");

if (!fileMy.open(QIODevice::ReadOnly | QIODevice::Text))
{
    QMessageBox::information(this, tr("ERROR"), tr("Daten konnten icht eingelesen werden"));
    return;
}
QTextStream stream (&fileMy);

int conterX = 0;
while (!stream.atEnd())//your error was here, you should use stream, not a file
{
      QString line = stream.readLine();
      QStringList list = line.split(",");

      QStandardItem *item1 = new QStandardItem(list.first());//first name
      model->setItem(conterX,0,item1);
      QStandardItem *item2 = new QStandardItem(list.last());//last name
      model->setItem(conterX,1,item2);
      conterX++;

}
ui->tableView->setModel(model);//setmodel

我能做到吗？

while (!stream.atEnd())
{
      QString line = stream.readLine();
      QStringList list = line.split(",");
      QString firststring;
      firststring = (list.first());
      QString secondstring;
      secondstring = (list.last());
      QString *secondstring = new QString(list.last()); 
      meinModel->setData(firststring, secondstring);

          }
