How to add newline to a QString?

[mimimeow]

I have an error message dialog where I need to pass in a QString.
I want to break up the string into multiple lines. If I add "\n" it didn't work, it's simply ignored.
How can I break up the long string into several lines? TIA for your help.

Well, \n should work, they should patch Qt on this one afaik ;)

But, as far as I remember, </br> could do the trick, as the contents in a QMessageBox is rendered as HTML like string.

Yes , "\n" works with QString , you can try the following code

@ QMessageBox::critical(this,"error","This \n is \n an \n error \n string !!!!!");@

that shows an error dialog like :

\n works when rendered as plain text, <br> works when rendered as html (textFormat: Text.StyledText)
\n is ignored when rendered as html, <br> is rendered as those 4 characters when rendered as plain text

\n works. Thanks @BrianDavis for sharing.
My code:

QStringList strs;
    strs.append("Toyota");
    strs.append("BUICK");
    strs.append("VW");
    strs.append("Mazda");

    QFile p("car.txt");
    if (p.open(QFile::WriteOnly | QIODevice::Text)) {
        QTextStream s(&p);
        for(QString line : strs){
            s << line << "\n";
        }
    }

@Jimmy-Crab hi and welcome to devnet,

QStringList::join would be simpler.
