Hey,
Because of a lack of accessible documentation of fengGui,
I'm in need on some assistance in using it. Because the javadoc will not load.

Now, I know its built on top of lwjgl, but how can you effectively use the two together?

Nifty Gui is nice too but its memory footprint disappointed me.

May, not January.

FengGUI was still being developed past that - I was submitting patches until about Jan 2010, when I left the company where I was using it, and there were a handful of other active forum users. But it did suffer from a main developer (possibly the previous one - my memory's hazy on the details) who didn't know how to use SVN branches, so decided to start a massive refactor in the trunk and then left it half-finished.

There should be a few examples which demonstrate how to use it with LWJGL, but if there's another library which meets your requirements I would try that first.

What about PureSwing? As far as I know, it has a LWJGL backend.

PureSwing is 'deprecated' (it works in OpenGL as I use it in my game, but it's alpha quality, wouldn't recommend it for other users).

While working on it I realized it will be better to start from scratch to achieve my goals. This new library is currently in development.

Ok, thank you for these pieces of information. Please feel free to create another thread to tell us more about your new library. I would have loved to use PureSwing with another backend based on Agile2D.

Oh, I see. That makes a lot more sense.
