[Moose-dev] Auto-updating the browser while changing tags without revisiting nodes on a tree

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].

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]

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
