Usage

From source file:TreeNodeVector.java

public static void main(final String args[]) {
    JFrame frame = new JFrame("JTreeSample");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    Vector<String> v1 = new TreeNodeVector<String>("Two", new String[] { "Mercury", "Venus", "Mars" });
    Vector<Object> v2 = new TreeNodeVector<Object>("Three");
    v2.add(System.getProperties());
    v2.add(v1);/*from www . j a v a2  s.  c om*/
    Object rootNodes[] = { v1, v2 };
    Vector<Object> rootVector = new TreeNodeVector<Object>("Root", rootNodes);
    JTree tree = new JTree(rootVector);

    DefaultTreeCellRenderer renderer = (DefaultTreeCellRenderer) tree.getCellRenderer();

    Color backgroundSelection = renderer.getBackgroundSelectionColor();
    renderer.setBackgroundSelectionColor(renderer.getBackgroundNonSelectionColor());
    renderer.setBackgroundNonSelectionColor(backgroundSelection);

    Color textSelection = renderer.getTextSelectionColor();
    renderer.setTextSelectionColor(renderer.getTextNonSelectionColor());
    renderer.setTextNonSelectionColor(textSelection);

    frame.add(new JScrollPane(tree), BorderLayout.CENTER);

    frame.setSize(300, 300);
    frame.setVisible(true);
