multiple sort

[caduel]

The sql-parsing approach is not that hard (at least for simple queries without union etc).

Apart from that, yes a custom QSortFilterProxyModel that uses several columns in QSortFilterProxyModel::lessThan() will work, too. (Just don't compare only the columns given in die indexes but the ones you are interested in)

The sql approach i think would be faster than QSortFilterProxy approach , mind you I have millions of row to sort right?

I think in my sort I would try to sort them SQL style first then if I can't I will switch to QSortFilterProxyStyle

any more ideas...

If you don't care about losing the selection and scrollbars position in the view then using the sql approach should be simpler but if you do care then you should use the proxy approach.
