Hi,

I'm working on my project Grafoscopio, to provide a outliner/notebook like experience to write and visualize data. Details can be found on [1].

[1] http://mutabit.com/offray/static/blog/output/posts/grafoscopio-idea-and-initial-progress.html

I want to create modal nodes by tagging them, so If I mark a node like code it can behave like a workspace and execute code. You can see a small demo of this feature on [2]

[2] https://archive.org/details/grafoscopio-tags-alpha1.mp4

My code for tagging nodes is this:

==[a]=============================================
UI>>addTagsTo: a Node

        "Tags the node passed as argument with a value from the collection of tags available"
        | selection |

        tagsAvailable isNil
                ifFalse: [
                        selection := UIManager default chooseFrom: tagsAvailable title: 'Elija una etiqueta'.
                        aNode tagAs: (tagsAvailable at: selection)
                        ]
                ifTrue: [self messageNoTagsAvailable].
        browser update.
=================================================

But I have three questions:

i. How Can I update the nodes views/behaviour without revisiting them? The code in [a] is updating the node trees, but not the particular node views.

ii. How can I made the code in a node tagged as "code" get executed?

iii. Can I embed playgrounds instead of workspaces in a browser pane, with the possibility to explore objects and get more details about them?

Thanks,

Offray
