QTextStream not adding new line

[hokie2012]

I am trying to write to a buffer and then to the screen, i am using

]buffer << j.value() << "|" << j.key() << "\r\n";

]buffer << j.value() << "|" << j.key() << "\r\n";

To copy to clipboard, switch view to plain text mode 

i have tried

"\n"
'\n'
'\r\n'
<< endl

and none of them will add a new line..any ideas?

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QString str;
    QTextStream stream(&str);
    stream << "foo" << "\n" << "bar";
    QLabel l(str);
    l.show();
    return app.exec();
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QString str;
    QTextStream stream(&str);
    stream << "foo" << "\n" << "bar";
    QLabel l(str);
    l.show();
    return app.exec();
}

works as expected. If it also did for you, then anything other in your code is wrong...

what else would be wrong in my code that would effect simply adding a new line

Does it work for you or not? and where do you display the text? Maybe there new lines are ignored.

EDIT: Or do you convert it afterwards in some way?

QString message;
    QTextStream buf(&message);
    int count =0 ;
    QMapIterator<int, QString> i(sortedFound);
    i.toBack();
    buf << "FOUND" << endl;
    while (i.hasPrevious() && count < n)
    {
        i.previous();
        buf << i.value() << "|" << i.key() << "\r\n";
        count++;
    }
QTextEdit label2(message);
 label2.show();

QString message;
    QTextStream buf(&message);
    int count =0 ;
    QMapIterator<int, QString> i(sortedFound);
    i.toBack();
    buf << "FOUND" << endl;
    while (i.hasPrevious() && count < n)
    {
        i.previous();
        buf << i.value() << "|" << i.key() << "\r\n";
        count++;
    }
QTextEdit label2(message);
 label2.show();

is what i have that doesnt work

Here we go! By passing the text to the ctor QTextEdit interprets it as HTML. Therefore you see no newline. Use QTextEdit::setText() or use QPlainTextEdit if you don't need HTML.
