Some time ago, I saw an example of an applet that used a JTree, but the display actually looked more like a JTable. Each node in the tree had columnar data. You could expand/collapse nodes, just like a tree, but when you expanded, for example, each new node had its column data displayed as well. Has anyone seen something like this? If so, could you point me to a technical paper, book, code sample, etc., that shows how this is done? Thanks!
