khtml consists of the KHTMLPart and KHTMLView. The view is a normal 
scrollwidget. Just inherit from this widget and make KHTMLPart use it as 
view. There you will get _all_ events. There is also a method somewhere to 
get the DOM object behind a coordinate of the mouse. It is used for example 
for links and selections at the moment.

right.

garbage ;-) in the KHTMLView's paint method the whole layout is first 
rendered into a QPixmap. So you're free to draw anything you want above the 
rendered stuff. For example you can draw a box while resizing an image.
