Interesting code???
« on: December 13, 2006, 08:19:40 pm »
Hi! I'm new in jpct (in java have looong time of programming)

I was trying several projects of 3d to integrate with swing applications (lightweight trouble... :P).  I have done this code... maybe it can be interesting to you...

The thing is to create a JPanel where you can put your world in order to integrate it with all the swing stuff... here you can see that the JMenu is "OVER" the 3d image and there is a first version of the component that can be a "lightweight" panel

Tell me you opinions...

Anyway... good work, mates!
