This class is used in Qt4 MVC architecture as a replacement
for too much slow toListView item based widget - it's about
70% faster.
toStorageObjectModel is read only model - there are no user
iteractions required.
See toStorage Objects and ObjectsModel.
See Qt4 docs to understand its MVC architecture.
