The latest Swing Designer v2.0.0 beta update is able to parse a wide variety of example Swing classes from various GUI builders like VAJ, VE, JBuilder, etc. Our goal is to be able to parse any reasonable example from any of the popular GUI builders.
If you have any Swing examples created with other GUI builders, please give them a try. If they don't work, please send them to email@example.com so that we can analyze them. The more "broken" examples we get, the better we can make the product.
