关于控制JPanel中的按钮进行滑动
问题是这样的，首先在JFrame中有一个JPanel，JFrame大小是500*500，包含了一个JPanel，在JPanel中有十二个按钮，界面只能显示六个按钮，还有六个没有显示出来，要求的效果就是，在下面放入两个按钮，一个left，一个right，可以通过这两个按钮进行一个切换，类似翻页效果（就是一次六个的切换），请各位高手帮帮忙，或者有什么好的方法推荐一下，有Demo参考最好了。

final JPanel left = new JPanel(new GridLayout(3,2,5,5));left.add(new JButton("1"));left.add(new JButton("2"));left.add(new JButton("3"));left.add(new JButton("4"));left.add(new JButton("5"));left.add(new JButton("6"));final JPanel right = new JPanel(new GridLayout(3,2,5,5));right.add(new JButton("7"));right.add(new JButton("8"));right.add(new JButton("9"));right.add(new JButton("10"));right.add(new JButton("11"));right.add(new JButton("12"));final CardLayout layout = new CardLayout();final JPanel pages = new JPanel(layout);pages.add(left, "left");pages.add(right, "right");final JButton showLeft = new JButton("Left");showLeft.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e){ layout.show(pages,"left"); }});final JButton showRight = new JButton("Right");showRight.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e){ layout.show(pages,"right"); }});final JPanel buttonPanel = new JPanel();buttonPanel.add(showLeft);buttonPanel.add(showRight);final JPanel main = new JPanel(new BorderLayout());main.add(pages,BorderLayout.CENTER);main.add(buttonPanel,BorderLayout.SOUTH);
