You use a QScrollView for you view.
There you implement 
 virtual void contentsMousePressEvent ( QMouseEvent * )

And you get sent (automatically I think) the relevant khtml::MouseEvent via the 
argument. I have not checked but I believe the khtml events are subclasses of 
the QMouseEvent.

You can cast the events to the right class from the html_events.h file and 
simply use that.


And as I see nothing static in that definition I don't see any reason to 
reimlement that.
