Hello everyone:
I have a subclass of QAbstractListModel, used from a QML list. This model has, for example, 3 items. It receives an update with 2 new items, and data changes in the other 3 elements. I call beginInsertRows/endInsertRows (because I have 2 new items), but my cuestion is... how should I emit the dataChanged signal? should i include the indexes for new items (from item 0 to item 4 then) or only for old data that really changed (from item 0 to item2)?
I have the same doubt when items are removed and there are data changes in items that remains.
thanks in advance and have a good day
