Write the content of a QStringList to a QTextStream

[graciano]

Hi
In this code i have to write all the items of a QStringList into a text file:

QString fileName = QFileDialog::getSaveFileName(this);
    if (fileName.isEmpty()){
        //
    }else{
        QFile file(fileName);
        if (!file.open(QFile::WriteOnly | QFile::Text)) {
            QMessageBox::warning(this, tr("Application"),
                                 tr("Cannot write file %1:\n%2.")
                                 .arg(fileName)
                                 .arg(file.errorString()));
        }else{
            QTextStream out(&file);
            //here
            out << "i want to write the content of the QStringList x here";
            file.close();
        }
    }

QString fileName = QFileDialog::getSaveFileName(this);
    if (fileName.isEmpty()){
        //
    }else{
        QFile file(fileName);
        if (!file.open(QFile::WriteOnly | QFile::Text)) {
            QMessageBox::warning(this, tr("Application"),
                                 tr("Cannot write file %1:\n%2.")
                                 .arg(fileName)
                                 .arg(file.errorString()));
        }else{
            QTextStream out(&file);
            //here
            out << "i want to write the content of the QStringList x here";
            file.close();
        }
    }

To copy to clipboard, switch view to plain text mode 

I read about using QVariant for this purpose!
Is this the right approach?
Can someone provide me with an example?

Thanks
