    Default Look & Feel

    Hello guys,

    Anyone can tell me why I don't see different look&feels? This is my main method:

    public static void main(String[ ] args) {
    		javax.swing.SwingUtilities.invokeLater(new Runnable() {
    			public void run() {
    				JFrame f = createAndShowGUI();
     
    				try {
    					UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    //					UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
    //					UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
    					javax.swing.SwingUtilities.updateComponentTreeUI(f);
    				} catch(Exception e) {
    					e.printStackTrace();
    				}
    			}
    		});
    	}

    I believe you must load the look and feel before making your window visible.

    I tried. This method actually refreshes the JFrame but it is still the same - look&feel doesn't change:
    javax.swing.SwingUtilities.updateComponentTreeUI(JFrame frame);

    Here is the way I try to do it:
    	private static JFrame createAndShowGUI() {
    //		JFrame.setDefaultLookAndFeelDecorated(true);
    		JFrame frame = new JFrame("Show Stack");
    		try {
    			UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
    		} catch(Exception e) {
    			e.printStackTrace();
    		}
    		StacksModel model = new StacksModel();
    		ShowStacks d = new ShowStacks(model);
    		List stacks = model.getModels();
    		for(ListIterator i = stacks.listIterator(); i.hasNext(); ) {
    			CardStack m = (CardStack) i.next();
    			m.addObserver(d);
    		}
    		JPanel cmd = new JPanel();
    		RoundButton button = new RoundButton("RUN");
    		button.setActionCommand("RUN");
    		JComboBox fromList = new JComboBox(model.getNames());
    		fromList.setActionCommand("FROM");
    		JComboBox toList = new JComboBox(model.getNames());
    		toList.setActionCommand("TO");
    		JLabel fromLabel = new JLabel("From:");
    		JLabel toLabel = new JLabel("To:");
    		cmd.add(fromLabel);
    		cmd.add(fromList);
    		cmd.add(button);
    		cmd.add(toLabel);
    		cmd.add(toList);
    		TestController controller = new TestController(model);
    		button.addActionListener(controller);
    		toList.addActionListener(controller);
    		fromList.addActionListener(controller);
    		frame.getContentPane().add(cmd, BorderLayout.NORTH);
    		JPanel p = new JPanel();
    		p.setLayout(new BoxLayout(p, BoxLayout.PAGE_AXIS));
    		p.add(d);
    		frame.getContentPane().add(p, java.awt.BorderLayout.CENTER);
     
    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		frame.pack();
    		frame.setVisible(true);
     
    		return frame;
    	}
     
    	ShowStacks() {
    		createAndShowGUI();
    	}
     
    	public static void main(String[ ] args) {
     
    		javax.swing.SwingUtilities.invokeLater(new Runnable() {
    			public void run() {
    				JFrame f = createAndShowGUI();
     
    /**				try {
    					UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    					UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
    					UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
    					javax.swing.SwingUtilities.updateComponentTreeUI(f);
    				} catch(Exception e) {
    					e.printStackTrace();
    				}
    */			}
    		});
    	}
    }
