Terry J. Reedy added the comment: (In 3.6, TreeWidget.py became tree.py.) Even though IDLE trees now appear to work correctly, including on Ubuntu, I am concerned about possible memory leaks, which are usually detected by repeatedly running a module's test file. Test_tree does not leak now, but it does not do much. In particular, it does not expand and contract items and move selections. TreeNode.draw has this note: "This leaks bindings until canvas is deleted", and I wonder if the same could be true in .drawtext.
Tree.py currently has these notes at the top: # - keep track of object ids to allow more careful cleaning # - optimize tree redraw after expand of subnode Currently, self.text_id is saved, but not used. Reusing canvas items should be more efficient. I won't edit tree.py immediately, as I intend to try using ttk.Treeview as a replacement. But we might instead update tree.py with ttk components. In the meanwhile, I will leave this open. ---------- assignee: -> terry.reedy versions: +Python 3.6, Python 3.7 -Python 2.7, Python 3.4, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6171> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
