It is *harder* than with QML - but possible. And I don't think it is that
hard. I am not saying that is easy, though. We used QtScroller
(kineticscroller) for instance, to implement smooth list view animation. If
you can render using the native API to an off-screen buffer, than it is
doable. I would even risk to say that hard is not the proper adjective here,
but instead laborious. To implement things like glowing, one can for instance
implement an event handler inside the style that monitors mouse events and
does the job of animating. Well at least it worked well for BlackBerry but I
can't say anything about Mac since I don't know the API.
If someone decides to give it a shot, though, I would be happy to help. Having
said that, I agree QML components are the most sensible way to go.
