Hi, When reading through the QSortFilterProxyModel i get the feeling that sorting is done on the source model regardless of a filter.
That is no problem with small models since sorting is quite fast, but that can be a bit of a pain if you have millions of entries (which filters reduce to hundreds) then sorting still seems to sort all entries (as if nothing is filtered) which takes a bit of time. A detour that would probably work is wrapping a QSortFilterProxyModel (with just the filter) in another QSortFilterProxyModel and sorting on that (since it's source would be a filtered model). This approach basically makes one a "QFilterProxyModel" and the other a "QSortProxyModel" which smells wrong. Another way would be to re-implement QAbstractProxyModel and implementing my own sorting and filtering, but i'd like to prevent that if possible. What i'm hoping for is some option in QSortFilterProxyModel where you can define how you want to sort: - Sort source model (sorts all data) - Sort proxy model (sorts data that passed the filtered) But such an option doesn't seem to exist.
