Hi Alex,
Try the attached code and see if that is what you
are looking for. The code is within init(), but
you could improve it by creating a self-contained
JPanel as a subclass of JPanel that will add the
text or events or both, then add it to a part of
the layout of the Container (in this case a JApplet).
Hope this helps. Regards,
Alejandro

Hi All,
Actually, all I want to do is to add a translucent JTextArea onto the
Canvas3D. I need the Canvas3D to be the background for this JTextArea. Is
there any alternatives for me to achieve this?
Thanks in Advance.
