JTree node problem?

[wangdong]

What I want to do that is to have two root nodes in a tree and each root node has subroots. So the tree structure will look like:

----Root 1
|-------subRoot1
|-------subRoot2
----Root 2
|-------subRoot3

I couldn't get it work. Anyone know how to do it?

DefaultMutableTreeNode[] root = {new DefaultMutableTreeNode("Root1"),new DefaultMutableTreeNode("Root2")};
			
DefaultMutableTreeNode subRoot1 = new 
     DefaultMutableTreeNode("subRoot1");
DefaultMutableTreeNode subRoot2= new 
     DefaultMutableTreeNode("subRoot2");
			
root[0].add(subRoot1);
root[0].add(subRoot2);

DefaultMutableTreeNode subRoot3= new 
    DefaultMutableTreeNode("subRoot3");

root[1].add(subRoot3);

jTree = new JTree(root);

Ok, I have a solution now. I need to create a node and set it visible to false. Then add more node into it.

Am I right? Or there is a simple solution?

That's absolutely right, because, by definition, a root has always at most one root.
