Glad to be able to help.

That's probably a good idea.

Thanks that did the trick.I found no info on that in the documentation. Should I submit a bug report? They could either update the documentation or change the sort routine in QTableView.

You likely need to emit layoutchanged at the end of sort. Remember to
update the persistent model indexes as well.
