Oh, you can solve this by reimplementing KParts::Part::hitTest,
which was added for this very purpose (well, for koffice :)
You get a QWidget as argument and depend on whether it is a
view of your document you either return this, 0L or possibly
a reference to an embedded child document (one without widget
maybe, if using a non-widget embedding, like in koffice) .

I see your hidden point though :-) : We might want to provide a
class in KParts which one can use out-of-the-box for multiple
views, as reimplementing hitTest is not something really convenient.

Hm, looking at the source I see that you are right though when it
comes to non-mouse activation (read: focusin) . Here we in fact
use widget() .

David, what do you think about calling findPartFromWidget( w, QPoint( 0, 0 ) )
(or -1, -1 or something) here?

Bye,
 Simon
