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   w  w w  .j a v  a  2  s  .co  m*/
    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);

From source file:TreeChangedRenderer.java

public static void main(String args[]) {
    JFrame frame = new JFrame("Changed Renderer");
    JTree tree = new JTree();
    DefaultTreeCellRenderer renderer = (DefaultTreeCellRenderer) tree.getCellRenderer();

    renderer.setFont(new Font("Dialog", Font.BOLD | Font.ITALIC, 32));
    int rowHeight = tree.getRowHeight();
    if (rowHeight <= 0) {
        tree.setRowHeight(rowHeight - 1);
    }//w w  w  . java2  s. c  o  m

    // Swap background colors
    Color backgroundSelection = renderer.getBackgroundSelectionColor();
    renderer.setBackgroundSelectionColor(renderer.getBackgroundNonSelectionColor());
    renderer.setBackgroundNonSelectionColor(backgroundSelection);

    // Swap text colors
    Color textSelection = renderer.getTextSelectionColor();

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