I have a working example of Count UI in morphic. Morphic-UI.st (You'll first need the Counts.st class from Downloads) It should show up as UI in the morphic world. Try the  CountValueViewMorph.


I wasn't able to create the same API for the UI package in morphic. I 
couldn't find a way to add morphs at particular coordinates within a 
view. Everything in Morphic seems to be added in rows and columns using a 
layout manager. A layout manager can be vertical or horizontal. Its 
possible to add an object per row/column. The object itself could be 
another layout manager ... so its very flexible.


The UI has a ModelValueViewMorph which generates buttons and text views 
as expected. The difference is in the layout of the view. The class has a 
vertical layout manager.


The buildViewOn: for each subclass will need a separate method to add 
each row in the view. In case of Count, it has three statements.
 - add the three buttons, a horizontal layout manager
 - dummy morph as spacer
 - add the display box


The main layout manager in this case has three objects.



Each subclass of ModelValueViewMorph will need to have:
 - separate methods to generate each row of the main view
 - buildViewOn: to add all the rows
 - initialize, this would create the model and call the appropriate method
   to open the view. This is required since its not possible to run 
   morphs from the workspace.



I think programming in Morphic world would be easier once the code gets 
documented. Since it doesn't require the MVC approach, it should be 
possible to collapse everything into a single class. I don't know whether 
this is good or bad as the students would already be familiar with the 
non-MVC approach since cs1502 has gone 100% Java.
