    Default keyboard listener not working

    I am using jPCT as a 3d engine and I cannot get any form of keyboard listeners to work. I have tried multiple different methods, and have gotten a variety of errors. If anybody can tell me how to implement a keyboard listener, I would really appreciate it. This is the most recent version of the program that compiles without error.
