JTree supports an unlimited number of nodes. However, if you have thousands of them all as the children of a single node, performance will suffer. Another possible cause of the performance problem is that 5000 nodes may take a considerable amount of memory. You may want to consider rewriting your TreeNode implementation to use some kind of disk-based access instead. -- Check out our latest white papers at http://www.datadevelopment.com/papers/index.html BladeNET Scores With Borland Enterprise Tools Team Development with JBuilder and Borland Enterprise Server Dolphin Data Development Ltd. http://www.datadevelopment.com/ "Chris" <zerol@263.net> wrote in message news:3f994daa@newsgroups.borland.com... > Hi, all > > I'm have a small problem with JTree. > When load 5000 nodes into a JTree, it's > works terribly slow. > > any idea? or how many nodes that JTree support? > > TIA. > >
