programatically select a tree node

Thread view: 
William Z. - 30 May 2006 21:50 GMT
How do I programaticlly select a tree node in my JTree after it's just
been created and added to my tree. I'm trying to select it (I'm
guessing this means highlighted and selected as if the user just
clicked on it) by the following, but this isn't working.

[code]
       // create new node and add to tree
    DefaultMutableTreeNode myNode = addNode(getMyRoot(), myInfo, true);

       // get the path from the root to the node
    Object[] objPath = myNode.getUserObjectPath();

       // and convert it to a Treepath, then select it.
    TreePath tPath = new TreePath(objPath);
       getTree().setSelectionPath(tPath);
[/code]

getUserObjectPath() does not do what you think it does. Check the API
documentation. You want getPath().
