How to set fixed width in qtextdocument?

[qwe3]

Hi,

I have QTextEdit object. It is not editable, readonly etc.

I don't know what text I will have on it, but I would like to have fixed width and change only height.

I tried with qtextdocument:

textEdit->document()-> something
textEdit->resize(something);

but with no good results.
