关闭一个可运行的JOptionPane

我有这个Runnable窗口：

EventQueue.invokeLater(new Runnable(){ @Override public void run() { op = new JOptionPane("Breaktime",JOptionPane.WARNING_MESSAGE); dialog = op.createDialog("Break"); dialog.setAlwaysOnTop(true); dialog.setModal(true); dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } }); 

我有可能在这里有一个计时器在1或2分钟内关闭它而不是单击确定按钮？

是的，诀窍是在调用setVisible之前启动Timer …

 public class AutoClose02 { public static void main(String[] args) { new AutoClose02(); } private Timer timer; private JLabel label; private JFrame frame; public AutoClose02() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) { } JOptionPane op = new JOptionPane("Breaktime", JOptionPane.WARNING_MESSAGE); final JDialog dialog = op.createDialog("Break"); dialog.setAlwaysOnTop(true); dialog.setModal(true); dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); // Wait for 1 minute... timer = new Timer(60 * 1000, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { dialog.dispose(); } }); timer.setRepeats(false); // You could use a WindowListener to start this timer.start(); dialog.setVisible(true); } } ); } }
