[Interest] QPlainTextEdit: autoformatting text (like autofill in emacs)?

[Wilhelm]

Hi all,

I want QPlainTextEdit to insert a new paragraph if the actual editing 
position exceeds a predefined width, say e.g. 80 columns.

I started googling but didn't find anything usefull: surely I missed the 
wrong keywords, please give me a hint how to implement this.

Thanks!
