When you set data it has different 'roles':
http://www.webtoolkit.eu/wt/doc/reference/html/group__modelview.html#gga0ae864e12320f9f89172735e075ed068a5ed17aded8a0e3b712698cf85a218f1f
.. so on the standard item 'setData':
http://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WStandardItem.html#afbe54e68e576c4902c9085f8966c93ef
It defaults to UserRole..
so on the model .. the sortRole .. defaults to 'displayRole'.
I'd call setSortRole on the model:
http://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WStandardItemModel.html#a3aa1f52a3ae23611267e049130cb472c
and pass UserRole in there.
That should set you right.
Kind Regards,
