QSortFilterProxyModel - sort strings

[DPinLV]

I am using this model with my overidden QAbstractTableModel model. The problem I see with the sort of the QSortFilterProxyModel is it incorrectly sorts my column that contains integers.

For instance, if the data is as follows:
2, 6, 1, 9, 0, 10.

It gets sorted as follows:
0, 1, 10, 2, 6, 9

Obviously, 10 should not follow 1. Is there a way to correctly sort this other than creating my own ProxyModel that derives from QSortFilterProxyModel?

Thanks,
DP
