Implemented QML Dynamic View Ordering by Dragging View Items using this Qt tutorial: QML Dynamic View Ordering Tutorial. Only changed original underlying model which is QAbstractListModel descendant in our case. Model stores data in a QList<QObject*> objectList; field type.
Was necessary to change items order automatically in original underlying model as well (not only in DelegateModel) for other C++ and QML consumers where this order matters. Implemented this by adding void ObjectListModel::move(int from, int to) to the ObjectListModel implementation like I've mentioned here on Stackoverflow:
However another model consumer like MapItemView fails to use the model after beginMoveRows/endMoveRows calls: moved indicator item disappeared on the map (not destroyed or visibility changed) and other manipulations with the item crashes the app.
Think Qt bug. Some other hacks like emitting dataChanged() signal, etc do not help as well.
