    Default How to make a JTree have multiple layers.

    I was able to get children but how do I get grandchildren?

    I was able to do it with arrays, but it has the unacceptable side effect of having the array toString as the name, which isn't what I want.

    I've tried the JTree(TreeNode) constructor but when I tried something like this:


    DynamicUtilTreeNode dutn = new DynamicUtilTreeNode("Bubba", names);

    Object[] values = new Object[3];

    values[0] = dutn;
    values[1] = "Abanca";
    values[2] = "Davama";

    DynamicUtilTreeNode dutn2 = new DynamicUtilTreeNode("Rilli", values);

    jt = new JTree(dutn2);

    And it's not showing the third level.

    Bubba's children aren't showing up.
