NetBeans team used the preview version of project Jackpot
to convert the whole NetBeans source code from Swing into SWT. I think this is a very interesting demonstration of the power of this technology. While I don't see much added value in this conversion (I always preferred the Swing UI - but this may be a personal bias) I think this is great news for people who prefer SWT. Now they can enjoy their favorite widgets even in the NetBeans IDE - perhaps this will give all SWT lovers a reason why to take a look at NetBeans.
