Recently a Spec documentation was released on-line, how it is related with the Polymorph project? It would be nice to read about the future of these projects. Is Polymorph discontinued?
回答1:
Polymorph is a UI framework. Spec is a UI description framework based on literal arrays.
In other words the widgets you see on the screen come from Polymorph. A UI builder takes a Spec specification and builds those widgets: "here's a button of this size, and this is its name".
In Squeak, the same relationship exists between Morphic or MVC, and ToolBuilder.
