使用Swing Timer暂时隐藏通知

我正在使用Swing Timer来制作webNotification ，一种自定义JFrame ，会在特定时间出现。 我希望用户可以选择单击“隐藏”按钮来取消通知，并在一小时后返回。 我怎样才能做到这一点？

javax.swing.Timer有一个初始延迟; 只需将其设置为60 * 60 * 1000 。 调用start()后一小时将调用actionPerformed() start() 。

附录：这是一个按钮的示例，它隐藏了它在指定时间段内的封闭窗口。

 import java.awt.EventQueue; import java.awt.GridLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.Timer; /** @see http://stackoverflow.com/questions/4373493 */ public class TimerFrame extends JFrame { private void display() { this.setTitle("TimerFrame"); this.setLayout(new GridLayout(0, 1)); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.add(new TimerButton("Back in a second", 1000)); this.add(new TimerButton("Back in a minute", 60 * 1000)); this.add(new TimerButton("Back in an hour", 60 * 60 * 1000)); this.pack(); this.setLocationRelativeTo(null); this.setVisible(true); } /** A button that hides it's enclosing Window for delay ms. */ private class TimerButton extends JButton { private final Timer timer; public TimerButton(String text, int delay) { super(text); this.addActionListener(new StartListener()); timer = new Timer(delay, new StopListener()); } private class StartListener implements ActionListener { @Override public void actionPerformed(ActionEvent e) { TimerFrame.this.setVisible(false); timer.start(); } } private class StopListener implements ActionListener { @Override public void actionPerformed(ActionEvent e) { timer.stop(); TimerFrame.this.setVisible(true); } } } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new TimerFrame().display(); } }); } }
