We have tried many tree libraries and the best is k_tree. Make sure you have version 3, it has many bugs fixed. k_tree is very well written and performs well with large data sets of arbitrary nesting.
We have also tried adding nodes dynamically to various tree components, but this always ends up in a mess. We have found that deleting all nodes in the tree and rebuilding the tree seems to be the only sure fire way to get all the nodes to display correctly. The k_tree implementation allows us to delete and rebuild the tree in under 1 second (over 160 nodes nested 15 levels deep). We are then able to use the handy k_tree functions to scroll the tree to display and highlight the new node. -p Josh McDonald-3 wrote: > > Anybody using k_tree? > > I'm having some problems forcing it to redraw.
