The cost of storing an extra reference in each object is on the order of a few bytes per item. Unless you have millions of items in your treeview (which generally sucks regardless of what you do, treeviews don't scale that well), this adds up to a tiny amount of memory. It is unlikely that a much better solution exists. This is premature optimisation. _______________________________________________ PyQt mailing list PyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
