Forgive the newbe level of this question.
I have define and declare a root node, jtree and model. I add nodes to the
model. The tree doesn't get updated.
Why?
I thought insertNodeInto fired tree updates.
I have to use model.reload() to update the tree.

TIA

Here's my test code:
//-------------------------------------
import javax.swing.*;
import javax.swing.tree.*;

public class TestTree {
    public static void main(String[] args) {
        DefaultMutableTreeNode root = new DefaultMutableTreeNode("top");
        JTree tree = new JTree(root);
        DefaultTreeModel model = (DefaultTreeModel) tree.getModel();
       
        for (int x = 1; x <= 10; x++) {
            model.insertNodeInto(new DefaultMutableTreeNode("node " + x),
                    root, root.getChildCount());
        }
       
        //model.reload();
        JFrame frame = new JFrame();
        frame.add(tree);
        frame.setSize(300, 300);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}
