Usage

From source file:Main.java

public Main() {
    super(BoxLayout.Y_AXIS);
    DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
    for (int i = 0; i < 14; i++) {
        DefaultMutableTreeNode node = new DefaultMutableTreeNode("Root" + i);
        node.add(new DefaultMutableTreeNode("Child" + i));
        root.add(node);//from  www  . ja va  2  s.c  o m
    }
    CustomTree tree = new CustomTree(root);
