To Jan and Andreas I have tested with ModelTest and it passes, but I think I have hacked my original model into insignificance, as the QTreeView certainly doesn't look like I want.
I'm going to give it a bit of a rest, and try again later. Thank you both for your kind help. -- Regards Alex _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
