This is one of the less nice solutions If I understand well, the QTextEdit accepts the <body> .. </body> HTML text with sufficient set of tags. Nevertheless, the original text is not HTML so that I need to translate. Okay, but I cannot append the text element by element because the intermediate text is not valid in general (missing end tags because they weren't reached so far). I need an auxiliary QString where I translate the text and then I need to display the QString as a whole. A single error in the original text can cause losing the whole output. Correct?

I would appreciate some kind of "rich text edit", perhaps, something derived from QTextEdit or QPlainTextEdit with formatting member functions. But this means understanding the bags or QTextManyThings objects.
