Ao adicionar nós ao meuDelegateTree, eles não aparecem visualmente na ordem em que os adicionei. Eu estive procurando por uma solução, mas não encontrei nada ainda. Existe alguém que saiba como mudar isso?

Desde já, obrigado!

EDITAR: Meu código

        GraphicalUserInterface gui) {

    /* Create a new tree */
    DelegateTree<Node, Edge> graphTree = new DelegateTree<Node, Edge>();

    /* Add all nodes and vertices to the tree */
    graphTree.addVertex(tree.getRoot());
    addChildren(tree.getRoot(), graphTree);

    /* Create the visualization */
    DynamicTreeLayout<Node, Edge> treeLayout = new DynamicTreeLayout<Node, Edge>(graphTree, 100, 100);
    VisualizationViewer<Node, Edge> vv = new VisualizationViewer<Node, Edge>(
            treeLayout);
    vv.setDoubleBuffered(true);
    vv.setBackground(Color.WHITE);
    vv.getRenderContext().setEdgeLabelTransformer(
            new ToStringLabeller<Edge>());
    vv.getRenderContext().setEdgeShapeTransformer(

    return gzsp;
