JOptionPane不会关闭

Question

我希望如此，当您单击“确定”或“取消”时，它会关闭。我应该添加什么代码？

rightbutton = new JButton("Right.");
add(rightbutton);
rightbutton.addActionListener(
    new ActionListener(){
        public void actionPerformed(ActionEvent event){
            //what do we want to happen when we
            //click the button
            final ImageIcon icon = new ImageIcon("C:\\Users\\Scr3am\\Desktop\\paypal.jpg");
            JOptionPane.showOptionDialog(null, 
                 "Congratulations, you clicked the button.", 
                 "Congrats", JOptionPane.DEFAULT_OPTION, 
                 JOptionPane.INFORMATION_MESSAGE, null, 
                 new Object[] { panel }, icon);

Answer 1

当你点击确定时，JOptionPane应该自动关闭，但是尝试添加System.exit（0）;到actionPerformed方法。

例如

rightbutton = new JButton("Right.");
add(rightbutton);
rightbutton.addActionListener(
    new ActionListener(){
        public void actionPerformed(ActionEvent event){
            //what do we want to happen when we
            //click the button
            final ImageIcon icon = new ImageIcon("C:\\Users\\Scr3am\\Desktop\\paypal.jpg");
            JOptionPane.showOptionDialog(null, 
                 "Congratulations, you clicked the button.", 
                 "Congrats", JOptionPane.DEFAULT_OPTION, 
                 JOptionPane.INFORMATION_MESSAGE, null, 
                 new Object[] { panel }, icon);
                 System.exit(0);
