Who told you parents are essential? Probably your parents... :-) I guess setting parents is good practice, but it's not essential. Perhaps https://github.com/leo-editor/leo-editor/blob/master/leo/plugins/nested_splitter.py#L865 does it implicitly. Attached is what I get when I select / Ctrl-B run the first part of the example, then add a Turtle pane, then select / Ctrl-B run the second half of the example. So it's visible and works. But if your goal's drawing trees in a QGraphicsScene I don't think you need to create a QGraphicsView of the scene using free_layout in the first instance, that can always be done later.
