如何使用QTextStream代替QDataStream进行QTableView的负载保存？

Question

I am newbie on QT, So when I try to load and save data from QTableView into txt files in linux using QDataStream I have a problem like this :

txt files contain data from tableview

All I want is the data in txt files easily to read, for example : data1;data2 data3;data3

So, how to use QTextStream instead of QDataStream, because when I'm using QTextStream I can write output in txt just like this :

QFile ofile("/home/rizi/LearnQT/tes");
ofile.open(QIODevice::ReadWrite | QIODevice::Text);
QTextStream out(&ofile);
out << line+"\n";

Each item in the model consists of more than a text. That's why write function requires a QDataStream instance. If saving only the text part of the data is ok for you then you can always:

qint32 n(model->rowCount()), m(model->columnCount()); 
stream << n << m; 
for(int i=0; i<n; ++i) 
for(int j=0; j<m; j++) 
stream << model->item(i,j)->text();
