UITextEdit

I am trying to create a text editor in squeak that has some extra features. I really want to be able to preserve the layout so it uses the scrollbar instead of manually wrapping the text.

It looks as if TextEditMorph has more control over that and PluggableTextMorph but I have trouble using
those objects.

Does anyone know or have any suggestions on how to make the UITextEdit comply with wrapping? Or another suggestion on text wrapping?
