[SailfishDevel] ListView vs Repeater

[Krisztian Olah]

       Hi Oleksii,
  It is the model that handles the actual removal, but I want a RemorseItem
to call it, which is in return requested by the delegate. I want all list
items to have their own remorse timer in case user wants to cancel one but
not the other.
  In my current version it works fine, except when the user scrolls away
too far the RemorseItem is destroyed and the file is left on the disk, but
come to think of it; perhaps I could just call the model.remove() function
when onDestruction() signal is emitted. Thanks, if I didn't write this
letter I might not think of it. :)

Anyway if you want to see the latest version you can have a look here:

I'd be happy for any feedback. :)

Thanks Kris
