You don't really need a new class. This works:

         model := TextModel new contents: 'Hi folks, \this is a 
multiline text, \see?' withNewLines .
         doWrap := true.
         m := TextModelMorph withModel: model.
         m wrapFlag: doWrap.
         m hideScrollBarsIndefinitely.
         m lock.
         m openInWorld

Locking the morph is not the ideal thing to do, as you can't grab it 
with the halo anymore. You can add a readOnly capability to 
TextModelMorph, that would be a welcome addition. Also, maybe some 
convenience method with code like my snippet above could be useful.
