[Cuis] PluggableListMorph

[KenD]

Hi Dan,

Good explanation.  I like good explanations.  8)

You might be interested in the code examples in:

I would note that the observer pattern discussion might be better served by the more modern #when:send:to: idiom.  [E.g. look at when:send:to: senders; Check the TaskBar for simple usage].

In particular, an observer can register for event updates and get a specific message. 

IMHO we should rewrite PluggableListMorph to use when:send:to:
