Different tooltips in JTreeTable

Question

Hi all!
I have a JTreeTable (the rows are the nodes of a tree), very similar to the one at
http://java.sun.com/products/jfc/tsc/articles/treetable2/
I'd like to add different ToolTips in every node (in the example in the sun's site, for example see as a tooltip the file's name). How can I do that? Should I do that in the cell render method? Has anybody any example about that?
Feedbacks are really appreciated!
Thanks
Franky

Answer 1

Sure, sorry for the mistake about the tags...Follows the class I use to render the JTreeTable. My doubt is that I have to do something with the mouse listener to active the tooltip, could it be?
Thanks
