How to get the TreePath of a newly inserted TreeNode

[Kevin Tysen]

DefaultTreeModel tmodel;
MutableTreeNode newProblem;
TreePath tp;
DefaultMutableTreeNode selectedNode= (DefaultMutableTreeNode) tp.getLastPathComponent();
int newIndex;
tmodel.insertNodeInto(newProblem, selectedNode, newIndex);

I insert a new node called newProblem into a parent node called selectedNode.
I have the TreePath to the parent node, but I want to know how to get the TreePath to that new node called newProblem.
Anyone know how?

To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates the problem.

Hello Kevin,

Your code doesn't make sense I'm afraid... You're inserting null into the TreeModel. If your newProblem is a DefaultMutableTreeNode then getting the path is easy:

DefaultTreeModel tmodel;
DefaultMutableTreeNode newProblem = new DefaultMutableTreeNode();
TreePath tp;
DefaultMutableTreeNode selectedNode= (DefaultMutableTreeNode) tp.getLastPathComponent();
int newIndex;
tmodel.insertNodeInto(newProblem, selectedNode, newIndex);

TreePath path = new TreePath(newProblem.getPath());

Sorry about not including a whole runnable code.
Anyway, line 8 is what I wanted to know. Thank you!
