Ahh, that's what you meant. I believe you can catch the corresponding key event yourself and then send a fake event with pageup/pagedown key to QTextEdit (unfortunately I can't see any public API for this).

sorry, I don't understand what your mean.

I layout the QTextEdit into a window widget. Is this the problem?
Could you by any chance provide a screenshot of the problem. I'm not sure if I follow either..
