Hi, friends:

I am new to Java 3D technology, I just made a code to let two cubes linked by
a line shown on screen, it looks great! now, I need to add a behavoir to the
cubes: when you click the cubes, a window(frame)will be poped out. I know I
need to employ a Picking event to trigger a window, I extend a
PickMouseBrhavoir class, and put a frame object inside as below:

class PickframeShow extends PickMouseBehavior {
Frame myframe;
public PickframeShow(BranchGroup b, Canvas c, BoundingSphere s, Frame
f) {
myframe = f;
myframe.pack();
myframe.setVisible(true);

}
}

but, this code doesn't work, anybody here can give me a hint?

Thanks in advance!

Eric
