This project is the model side of the Swing Framework and Components (SFaC). If your doing a clean separation between model (or business) and view (or GUI or rendering) parts of your application, (like in the MVC pattern), then the only classes of SFaC your model can access are in this project. On the other hand, the classes in sfac-core project are GUI-specific and should not be known by your model.

The newest version!
