There is no sin is using less than all the features of a widget. Anyway, think of the tree having one node, which you can hide (not show), representing the table, and n leaves, representing the rows of the table, which you do show.
Terry, This explanation clarifies what I've read about the tkinter tree.
If you sort the selection by some categorical field, then you can make the display hierarchical by adding expandable rows for values of the sort field. Think of database reports where summary lines can be expanded and contracted.
My current thinking is that the sorting will be done by the SQL statement based on user input (and that's another widget I need to learn) so the output in the treelist will be as correct. Thanks very much, Rich -- https://mail.python.org/mailman/listinfo/python-list
