I wouldn't call this implementation ready for frameworks, though - it just resets all the time, which is very slow as it forces views to destroy and recreate delegates instead of just updating them. A better implementation would just (re)filter source rows corresponding to the current page. This could be done as a subclass of QSortFilterProxyModel or custom; KItemModels' KRearrangeColumnsProxyModel can serve as inspiration to some degree. As it stands I wouldn't actually use this if it was in the framework.
