这是我对您的GUI的看法，看来工作还可以。非常激烈。您如何执行更新？在另一个线程上？
final JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.getContentPane().setLayout(new GridLayout(3, 1, 20, 20));
final JPanel[] panels = new JPanel[3];
for (int i = 0; i < panels.length; i++) {
panels[i] = new JPanel();
panels[i].setOpaque(true);
frame.getContentPane().add(panels[i]);
}
frame.setVisible(true);
ActionListener action = new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
Random gen = new Random();
Color color = new Color(gen.nextInt(256), gen.nextInt(256),
gen.nextInt(256));
frame.getContentPane().setBackground(color);
for (int i = 0; i < panels.length; i++) {
color = new Color(gen.nextInt(256), gen.nextInt(256),
gen.nextInt(256));
panels[i].setBackground(color);
}
}
};
Timer t = new Timer(100, action);
t.setRepeats(true);
t.start();
