QTextEdit and CR
I'm having trouble filling a QTextEdit object with a series of numbers, each one of which is to appear on a separate line. For example,
for (int i = 1; i < 100; i++)
blah += QString::number(i);
blah += tr("\n");
qDebug() << blah;
testWidget = new QTextEdit(blah);@
The call to qDebug() prints just what you would expect: the numbers from 1 to 99, each on a different line. But the QTextEdit object displays the numbers on one long line.
If it matters, I'm on Windows. The QTextEdit object is display with everything at the default settings.
I tried various combinations of using (or not) tr() in the hope that it might perform some magic, and I tried "\n", "\n\r", "\r\n" and (just for kicks) "\r". They all do the same thing: the CR and/or LF becomes a space.
This seems like the sort of thing that must have been discussed umpteen times, but I haven't found anything helpful.
tr won't help you here, it's only there for internationalisation purposes.
The problem lies in the fact that the constructor interprets the string has html.
Assuming that you're not joking about the html, how are you supposed to turn that "feature" off?
I tried QString::fromLatin1(), fromUtf8(), fromLocal8Bit(), and even the constructor QString(1,'\n'). I get the same result every time. It's a mystery why this problem (and I can't say that I understand what is going on here) hasn't arisen for me before.
I understand what you mean now. The QString is where the problem lies. I need to call QTextEdit.setAcceptRichText(false). Thanks.

You can use setPlainText()
That, or you have to create a valid html string containing your series of numbers or simply use setPlainText(const QString&)
