Hi Kris, Aha! So what you want is:
1. User selects to remove an item in the ListView. 2. RemorseItem activates so user can cancel the deletion. 3. When timer times out, the item is actually deleted from the model. And, in this case, 3. breaks when user scrolls the item away before timeout: delegate is deleted -> RemorseItem never times out -> item not deleted from the model. Then yes, performing deletion in Component.onDestruction() is the way Jolla's standard apps do (at least I've seen it in one of their apps). So you're on the right track :-) On 13/10/14 23:54, Krisztian Olah wrote: > 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.
