thanks for all the answers so far. Here goes another...
Is it possible to build a hierarchical tree with checkboxes? It seems a good UI for configuring a large number of boolean options. I'm thinking of something like this: http://www.javaworld.com/javaworld/jw-0 ... xtree.html
It is really important that this tree would be collapsible because we have something like hundreds of rules that can be set on or off. So we badly need a tree-like interface, a normal list is too cumbersome. Now, from what I've seen, TreeControl only takes string values, and cannot use anything else. Or maybe I'm wrong?
I know I could implement some listeners and use a scrolled list of checkboxes on the lowest level of my tree instead of nodes but the disadvantage would be that a user couldn't switch off and on whole categories of rules...
Thanks for all the help so far
