No such class in the J2SE. What are you talking about?

>..., n in it i have a Jtree.

Same for Jtree. If you mean the Swing based JTree,
please refer to it as javax.swing.JTree (using correct
UpperCase), so we can all be sure we have the same
understanding.

OK - what code do you have so far?

Post an SSCCE* to this forum. Note that an
SSCCE* is a *very* specific form of code.

Please read this document carefully, before posting..

Please try not to sound quite so pathetic.

That would seem to be the problem of any
'we' too foolish or shy to ask for clarification.
(It becomes my problem, if I am *asking* a
question. In that instance, I generally take
more care.)

And as an aside Brandon, I had vaguely
hoped that my strategies for replying to
posts would become more clear to you as
you gained 'experience'.

It seems that is not the case, so I will simply
point out that your snipes are not important
enough, for me to bother making further reply.

Use that code example and modify it to your liking.

The key here is the reload() function if you are using a
DefaultTreeModel object.

Err... I guess copy and paste the link... stupid newlines. I'm not
sure I like the word wrap functionality of gg.

As a fellow user of the GG WITUN, I find
this inability to post long links correctly,
to be quite irritating.

If GG does not get there act together soon,
I may be forced to go back to using dedicated
news client.
