[maemo-developers] How to get kinetic scrolling working using Qt creator

[From: Daniil Ivanov]

Hi Sudheer!

  There are many bugs there. For example you don't need centralWidget
at all, place scrollArea instead of it.
  Then you create multiple layout, set them to widgets and never place
them into scrollArea.
  On desktop you don't have scroll bars as well.

Thanks, Daniil.
