Listview viewing order
-
I have a listview in which I can change the order by dragging an item (QML Dynamic View Ordering Tutorial 1 - A Simple ListView and Delegate)
My question now is "how can I read back the viewing order after manually sorting the view"@ThMars
Since the model is in a separate file/component, create another instance of it, which of course will have the initial order -
I do not want the original order to save but read / get from the listview the order that is established after the items have been dragged to their new positions in the view. My model is derived from an array and I have to change the order of the array conform the view.

@ThMars
k, my fault.
Oddly I think there is no convenient way. A Workaround could be to make the index part of the model data (in the ListModel), then access it this way:
The example uses a proxy model (DelegateModel), which provides a items property of the DelegateModelGroup, which provides a get() method.
And returns a JS object with a object with certain properties:

Ok but then again that wil be the original index and that is not what I want, I will try to make use of the index when the items are moved (listmodel.move(from, int to, int n)). Like you said probably not a simple way.
@ThMars
then check the itemsIndex property of the returned object
