I needed to use a TreeTable for the program I was writing and it struck me
how very little information there is about this subject. Ok, there are a few
examples on SUN's website, but they are needlessly complex. So I decided to
make a generic implementation along with a couple of examples. I also
improved upon the original JTreeTable by making it sortable and by adding a
few functions which help with opening/closing nodes. It's not in an
extensive tutorial form, but I hope the examples are easy enough to
understand for everyone to start playing with it.

you can take a look here:
http://cal007300.student.utwente.nl/treetables/

The examples are as below:
- An example of a simple (sortable) JTreeTable
- An example which shows how to update/sort the treetable when you add
nodes every second.
- An example which shows how to update the nodes in a table (in this case
integers which are represented by a JScrollBar) and which shows how to make
the 'parent' nodes represent the average of their child nodes.
- An example (not really treetable though) which shows how to have working
hyperlinks in a JTable.
- An example which shows how to have working hyperlinks in a sortable
TreeTable.

Also check out the media section :) (totally oftopic, but nice nonetheless)

If you like it, I would ask of you to create one small example to show
something of which there is no example yet, so I can add it to the examples.
Also, for bug reports (and fixes!), new features, improvements, corrections,
hate and fan mail you can contact me at vincentv@thevoid.demon.nl
