Ah, no, I meant something different: The mouse wheel event should not be 
swallowed if the textarea cannot scroll any further down. The wheel event 
should then be passed up to the parent khtmlview so that it can scroll the 
whole document.

Yeah, it was wrong, but QApplication::sendEvent is wrong, too. 


During investigating the event flow, I found a flag "tabChangesFocus" in the 
qtextedit code. It can be modified through the method

QTextEdit::setTabChangesFocus(bool).

If you simply use that function, you neither have to intercept event(), nor 
keyPressEvent() or focusNextPrevChild().
