Re: [SailfishDevel] ListView vs Repeater

[Oleksii Serdiuk]

Hi Kris,




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);




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


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

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

               Hi everyone,

   I need some help between choosing ListView or Repeater.
I've got a SilicaListView whose elements I want to remove(only remove,
never add) dynamically from GUI. When I have fairly a long list
count(~25), reaching the element with
ListView.contentItem.children[index] is not possible for the mid to end
of the list, probably because ListView destroys items that are not
visible. When that happens children[index] will not refer to the same
element as model.index and therefore I cannot call remove() on the item.
Using a Repeater would of course prevent this, but I don't think I can
have a RemoveAnimation and I think I would have to reset the model.

   Is there another way that I didn't think of that would allow me to
remove items from my model with animation and would allow me to have a
list up to 1000 members(in real use it will probably be under 100) long?

       Thanks in advance
                Kris
