[Qt-interest] QTextDocument and "\r\n" new-lines

[Constantin Makshin]

Have you tried to open the file with QIODevice::Text flag set? I.e.  
something like

QTextDocument doc;
...
QFile file("foo.txt");
if (file.open(QIODevice::WriteOnly | QIODevice::Text))
{
     QTextStream stream(&file);
     stream << doc.toPlainText();
     file.close();
}
...
