so i'm trying to write myself a file manger, as i'm fed up with all the ones i've seen.

i've got a JTree set up and displaying properly, working off a self-made class that extends TreeModel. the problem is, i don't want to have to determine the entire tree at once, i'd just like to have it discover the tree two levels deep at a time, continually discovering the next two levels as i click on the tree displayed, so its always two steps ahead of me, but doesn't waste time determining the _entire_ tree when it initially loads. so. i have it set up to parse the first two levels of the tree from the root i pass it and that works fine. then i wrote a TreeWillExpandListener to force my TreeModel to discover further levels as I click through the displayed JTree. My TreeModel is updating, but the JTree is not, how do I get the JTree to update its display?

[ thanks ]

thanks stu_design. while not exactly solving my problem, it made me look at a couple of methods more closely and i found the problem there, issue with passing by reference and scope... so thats squared away now, thank you much.
