I would like to add a vertical line that would mark 80 characters in QPlainTextEdit. I looked at docs but I couldn't see anything in docs. Do I need to paint it somehow myself?

1Yes, you need to paint QFrame onto QPlainTextEdit widget. – Blood Sep 09 '12 at 19:20

Are the characters supposed to have fixed width? – Luca Carlon Sep 09 '12 at 19:53

Yes, they should have fixed width. How should paint QFrame onto a QPlainTextEdit. Could you show me some example? – gruszczy Sep 09 '12 at 19:56

I think one possible way is to reimplement the paintEvent() and draw the line using a QPainter after calling the base class implementation. The position of the line might be computed using QFontMetrics.
