[squeak-dev] Looking for a multi-select capable TreeMorph

For the DeltaStreams UI, I have long been needing a TreeMorph
that was capable of having more than one element selected, in
order to display deltas like:

- Collection>>#do: changed
- Fix bug 6982
  - Load Float-readFromManyDigits-Test-M6982-nice.1.cs
    - Float>>#readFromManyDigits changed
    - ...
- Integer>>#bitAt: changed

So far, I've been making do with a PluggableListMorphOfMany,
because I haven't yet set up the integration with Installer,
Monticello, and the chunk reader that would allow such deltas to
be created. However, I am getting ready to start making this
kind of annotated delta, and the UI
must be able to display them. So, do I need to roll my own
morph?

DeltaStreams UI only uses 100% Morphic, for maximum
compatibility with old squeak releases.

An hierarchical list morph may be what you want. Try the ObjectExplorer to see if this is this kind of interface will be satisfactory.

I am using s SimpleHierarchicalListMorph with my own wrapper and it works well for me. It should be possible to xtend it with multiple selection and make other adaptions. I can give more info about its architecture if you decide to try it.

Cheers
