You have three objects: SystemWindow: to present the view TextEditor: to represent the the functionality of a text editor TextModel: to hold the text Then there is also TextModelMorph... I find the whole Text model in Cuis very difficult to understand. I suspect it is the result of a legacy code from the '70 with multiple partial refactorings ending with code not well designed, but it works. It is very far from any MVC/MVP pattern, the responsibilities between the involved objects are interlaced making hard to understand the logic. I will never pick this as a topic for a learner. You have only scratched the surface. Take another topic, no need to constantly hit the head on the same wall.
