help coding: bug 327896

[Boudewijn Rempt]

I only took a quick look, so I haven't got a full solution yet, but:

* you don't need the signal/slot connection for the wheel event; the event handler is nested, so the toplevel widget gets the events for all subwidgets that don't handle the events explicitly.

* you need to accept() the event and otherwise ignore it

* and you probably need to set an event handler on the tableview object, as sven said on irc, to capture the event before it handles it itself.
