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 void actionPerformed(ActionEvent ae) {
    DefaultMutableTreeNode dmtn, node;

    TreePath path = this.getSelectionPath();
    dmtn = (DefaultMutableTreeNode) path.getLastPathComponent();
    if (ae.getActionCommand().equals("insert")) {
        node = new DefaultMutableTreeNode("children");
        dmtn.add(node);
        ((DefaultTreeModel) this.getModel()).nodeStructureChanged((TreeNode) dmtn);
    }//from   www  .j a v a2  s. c o m
    if (ae.getActionCommand().equals("remove")) {
        node = (DefaultMutableTreeNode) dmtn.getParent();
        int nodeIndex = node.getIndex(dmtn);
        dmtn.removeAllChildren();
        node.remove(nodeIndex);
