Removes newChild from its parent and makes it a child of this node by adding it to the end of this node's child array.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root Label");
    root.add(new DefaultMutableTreeNode("Node Label"));

    JTree tree = new JTree(root);

    JFrame f = new JFrame();
    f.add(new JScrollPane(tree));
    f.setSize(300, 300);//  ww w. j  a v a2  s  . c  om
