Depending on your needs, you could treat the attributes as items as well. Then you can have a custom delegate who would reassemble it all. If you're just hiding dext, it may be overkill, but if you want interactivity with the element attributes, it could be a better approach. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
