title: QScrollArea - how to enable touch interactions to scroll to next item?
body: <p>I'm using the Nokia Qt SDK and designed a small banner carousel in the top area. It looks like this:</p>

  <p>The hierarchy looks like:</p>

  <p>After installing this in the emulator, I try to make it scrollable (flinging). It's a simple task I would guess (like <code>ScrollView</code> in Android, or <code>UIScrollView</code> in iOS), but so far no joy. All links in the internet point me of custom scroll implementations etc etc. which I don't want to do nor expect to do as Qt should be a higher level framework? What is the state of the art here? ;-)</p>
  
  <p>Question in short: How can I make this <code>QScrollArea</code> respond to touch (fling, scroll, drag etc) events and reveal the other widgets in the queue? I'm not expecting it to be able to "snap" into a child widget (which is another requirement later ;)).</p>
