java - How to update JTree elements

Question

I use JTree with TreeNode which extending DefaultMutableTreeNode.when I add new node,i cant update JTree.Any help will be appreciated

Answer 1

Actually, it is enough to reload the parent node. Internally,

public void reload()

is using

public void reload(TreeNode node)

but with root as its parameter, so, unless you are updating the direct root's leaf, you are better of using a more fine-grained version.
