(Qt example) using count as model has implications when you need scrolling

When using count as the model in ListView, the problem is that model value will be changed whenever we add or remove an item, and the scroll will be reset. Using a QAbstractListModel is a better solution, because the model is a QObject, and its value (reference/pointer) won't change when we change it, thus eliminating the need to do special handling when the count changes.

Yes, that's true. I use QAbstractListModel in my real world code. It is a bit trickier to do and that's why I use the other mechanism for simplicity. But it would be worth adding an example.
