[Cuis-dev] dependency mechanism for TextModelMorph

[Hilaire Fernandes]

change. You don't need to set dependency there.

text: aString
     text := aString asString copy.
     self changed: #text.
     self changed: #clearUserEdits.
     self changed: #relabel "Same as self triggerEvent: #relabel"

Your Model object is the one holding your data, for example an Person 
object with attribute as firstName, famillyName.

In the decoupled paradigm of MVC or MVP, TextMorph is the view, hooked 
to a model. When there are changed in the TextMorph it
