With the following code, JFrame frame = new JFrame("frame"); frame.add(BorderLayout.CENTER, new JScrollPane(new JTree())); frame.add(BorderLayout.SOUTH, new JLabel("label")); frame.setSize(200, 100); frame.setLocationRelativeTo(null); frame.setVisible(true); Reducing the size of the window until a scrollbar is shown, you can see a tree icon is painted over a label.
