Returns a new path containing all the elements of this path plus child.

Usage

From source file:Main.java

protected static void expandTree(JTree tree, TreePath path, Hashtable lookedAt) {
    Object node = path.getLastPathComponent();
    if (lookedAt.containsKey(node))
        return;//  ww  w  . ja  v a 2 s . c o m
    lookedAt.put(node, node);

    Vector paths = new Vector();
    tree.makeVisible(path);
    int childCount = tree.getModel().getChildCount(node);
    for (int i = 0; i < childCount; i++) {
        Object child = tree.getModel().getChild(node, i);
        TreePath p = path.pathByAddingChild(child);
        expandTree(tree, p, lookedAt);
    }

        // since a non-leaf might have 0 children which would be
        // useless to expand
