update treenode's parent in jtree

[mark goking]

hi. i have no problems calling nodeChanged() for the child node. my problem is how have the parentnodes update themselves?

calling nodeChanged like nodeChanged(dmtn.getParent()) where dmtn is a DefaultMutableTreeNode messes up my JTree. any ideas?

well, never mind. ;)

i just had to pass the root treenode in nodeChanged() to update all nodes.

If you are using DefaultMutableTreeNode, you can update by calling setUserObject on that node. and call repaint/revalidate on tree.
