GUI Libraries and LeJOS

[MaR1oC]

Why there is no GUI API included in LeJOS NXJ API releases?

I am asking because I have not found any GUI Libraries and it's really blocking my work and I think I does so to many others.

You want to have a GUI on the NXT's screen? What kind of GUI classes are you expecting?
For programs that run on the PC (and communicate with the NXT via USB or bluetooth), you can use Swing GUI components.

However, I am not able to distinguish where Swing Libraries are located http://lejos.sourceforge.net/p_technologies/nxt/nxj/api/index.html

Well, first of all, your link points to the documentation of the classes on the NXT. Also note, that the link is outdated. The proper link would be:
http://lejos.sourceforge.net/nxt/nxj/api/index.html

If you want to learn about the classes available in the leJOS libraries for the PC, then you should take a look at
http://lejos.sourceforge.net/nxt/pc/api/index.html

But note, that this link only covers the documentation of the classes provided by leJOS. The JDK comes with many more, including Swing, and the documentation can be found here:
