Hi everyone,
I'm trying to learn swing and I was thinking you guys may know a really good swing based open source application that I could study and inspire from. I'm looking for something that has a real world use, not just some concepts explained (like examples in most books and tutorials).
Thank you!
Maybe you could have a look at the open source NetBeans IDE. It is huge, but it is using Swing intensively and is well designed and documented. Moreover, it is also a generic platform to build modular GUI applications.
You could take a look at the jgoodies examples. They are not plain swing though, and I don't know the license.
The Swing Tutorial is filled with excellent code, and the Swing code itself is available for study in most IDEs.
In the same spirit as the answer suggesting to check NetBeans, I would suggest to get the sources of IntelliJ IDEA Community Edition and IntelliJ Platform from their git repository. At some point, IDEA was IMO a state of the art Swing application (fast, responsive, not ugly, nice user experience, etc).
It's certainly less well-known than some of the other projects mentioned here, but have a look at GoGrinder. The code is well written and documented.
It might also be a good idea to look for something that you'll actually use. I find it easier to read the source of applications that I'm familiar with from using them.
