There is any way to run a minimal GUI with a tree using your example? I'm still missing a key concept on how to use spec and binding between widgets.

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.

 

Cheers,
