When the source model emits dataChanged, it may tell which roles have been changed. That information was lost when using a QSortFilterProxyModel -- the proxy simply dropped that argument (meaning "all roles may have changed"). It's instead a good idea to forward the roles argument, as it may minimize hits on the proxy (on unchanged roles). [ChangeLog][QtCore][QSortFilterProxyModel] QSortFilterProxyModel now properly forwards the roles that have been changed when the source model emits dataChanged().
