Happily, this is pretty much moot, because @pyplot actually does work in the VR pane. Edward -- You received this message because you are subscribed to the Google Groups "leo-editor" group.

First you execute the top part, i.e. import, class def, and c.free_layout.get_top_splitter().register_provider(TurtleProvider(c)) then (easter egg menu) right click a divider, select Insert, which creates an action button, then click that to open the 'Graphics scene turtle' pane. Then run the second half of the code. The above worked for me in vanilla (HOME=/tmp) Leo.

I see the same behavior on Ubuntu or Windows. The code you gave shows nothing in the allocated window area. Modifications of the code show the staircase in an external window.

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.

Terry, please explain how provided widgets get a parent
I can get a Turtle window working outside the free_layout/nested_splitter framework. The graphics window is a separate window, as expected. But I'm stumped at how the widget returned from ns_provide eventually gets a parent. I don't see that happening in the NestedSplitter class. For instance, in either ns.replace_widget or ns. replace_widget_at_index. Well actually, there are calls to setParent(None), but why would that help? Without a parent I don't understand how the Turtle widget will ever become visible. Edward -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
