Get CSV from QSQLTableModel with correct Locale

Question

I'm trying to convert the QTableView filled with QSQLTableModel data into CSV file. My current code is the following (actually similar to what was posted here already):

QFile f( "table.csv" );
if (f.open(QFile::WriteOnly | QFile::Truncate))
{
    QTextStream data( &f );
    QStringList strList;

    for( int r = 0; r < ui->table->model()->rowCount(); ++r )
    {
        strList.clear();
        for( int c = 0; c < ui->table->model()->columnCount(); ++c )
        {

            QVariant data = ui->table->model()->index( r, c ).data();
            strList << "\" "+data.toString()+"\" ";

        }
        data << strList.join( ";" )+"\n";
    }
    f.close();
}

This works perfectly, except that the locale is incorrect, i.e. points/commas in doubles, dates etc. The application locale is correct however, QTableView displays everything correctly.

Is there any way to set QLocale or to use it somehow when converting QVariant::toString ???
