I stumbled upon this blog where the developer did some very interesting things with JTree
The strange things is I was not looking for GUI technology, but found this code nevertheless quite atrractive and well constructed.

Ofcourse I have no affiliation with the developer of this component, thus I cannot gurantee the safety of this code. But it was safe/sound on my computer.

Well, here is the link, enjoy.

I ran the JNLP and it looks pretty cool. I was completely unaware of the entire JTree class despite my heavy interest in Java.

I suppose if you had a major application in Java this would come extremely useful in writing Help files.

The Help application would display a GUI with 2 Panes, the left being the JTree representing a table of context or something of the sort and when you clicked on a specific tree it could immediately draw information on that subject in the other pane.

Looks very interesting, I might look into implementing it into a future project of mine.
