approach. Is there a reason why in Squeak it is so different?
Alexandre, the version of Mondrian in Squeak is a complete reimplementation with a completely different model behind (not graph based with edges and nodes) and a completely different output model (not based on VisualPart/VisualComponent, not based on morphs). Starting from that model Doru (and maybe others) refactored towards an more similar implementation with a VW compatible API. I don't know how close the refactored code is, but obviously there are differences.
