[SailfishDevel] ListView vs Repeater

[Oleksii Serdiuk]

Hi Kris,

If I understood you right, why do you try to remove list elements 
directly from the ListVie. You should be removing them from the model 
and it will also remove components from the list.

See http://qt-project.org/doc/qt-5/qml-qtqml-models-listmodel.html

You can access ListView's model through its 'model' property:

 > listView.model.remove(index);


If you'd like to animate the removal, set 'remove' property of ListView 
(SilicaListView is based on ListView) to some transition animation.

http://qt-project.org/doc/qt-5/qml-qtquick-listview.html#remove-prop


That would be a "proper" way to do it :-)
