    what is missing ? this is a minimal gui with a tree component.

    Ohh, what is missing is not in the example, but in my
    understanding on how to use/start it. I would expect for something
    like "example openWithSpec" to start deconstructing it, but I'm
    still lost about it. I will be working on it today and tomorrow to
    see if I can come with better questions.


Ok, for this example you can just start it with:

TreeDemo new openWithSpec

It opens a window with two panes, the upper pane shows a tree with some nodes (subclasses of class Morph) The lower pane shows the text(name) of the selected node. You can change and accept (cmd+s) the text in the

lower pane, which will update the name of the tree node.
