如何在GUI中出现另一个JOptionPane时关闭一个JOptionPane

Question

正如您从上述主题中看到的那样，
我想知道如何解除由于另一个JOptionPane而变得不相关的JOptionPane，并且因为用户，出于某种原因，并没有通过他自己点击确定按钮来解除第一个按钮（例如）。

我已经看到了在其他网站类似的问题的一些洁具，人们建议简单地做：

JOptionPane.getRootFrame().dispose(); 

但我怎么能存储每个JOptionPane的我，并能够只辞退参考想要一个。
感谢

代码示例：

package Gui; 

import javax.swing.JOptionPane;

     //Please note that this OptionPane is coming in my real program always after the first JoptionPane 
     //I want that if I've reached the line in the code that need to show this second JoptionPane, I will first close the first JoptionPane 
     //Else you will dismiss the last JoptionPane and then the first one and I don't want to give the user two JoptionPane to close, it's annoying. 
     JOptionPane.showMessageDialog(this, "Set your move now please","Game started",JOptionPane.INFORMATION_MESSAGE); 
    }           

    // Variables declaration - do not modify      
    private javax.swing.JButton jButton1; 
    // End of variables declaration     

}

我会建议ŧ帽子你

• 创建一个JDialog你的JOptionPane（该JOptionPane API会告诉你怎么做），
• 然后使用的SwingWorker不管什么后台任务要做到这一点应该关闭主Swing线程来完成， EDT，
• 然后在后台任务完成时调用的SwingWorker的done()方法中，处理JDialog。
• 然后将立即调用下一个JOptionPane。

例如，以下代码使用Thread.sleep（3000）进行3秒睡眠以模仿需要3秒的后台任务。然后，它会关闭第一个对话框并显示第二：

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { 
     JOptionPane messagePane = new JOptionPane(
      "Board was sent for validation check\n Please wait...", 
      JOptionPane.INFORMATION_MESSAGE); 
     final JDialog dialog = messagePane.createDialog(this, "Board Sent"); 

     new SwingWorker<Void, Void>() { 

     @Override 
     protected Void doInBackground() throws Exception { 
      // do your background processing here 
      // for instance validate your board here 

      // mimics a background process that takes 3 seconds 
      // you would of course delete this in your actual progam 
      Thread.sleep(3000); 

      return null; 
     } 

     // this is called when background thread above has completed. 
     protected void done() { 
      dialog.dispose(); 
     }; 
     }.execute(); 

     dialog.setVisible(true); 

     JOptionPane.showMessageDialog(this, "Set your move now please", 
      "Game started", JOptionPane.INFORMATION_MESSAGE); 
    }

简单的答案，那不可能的，因为只有一个JOptionPane可以在当前的时间存在，如果你想解决您的问题，那么你必须创建JDialog#ModalityType(Aplications???)或JWindow，那么你就能够显示JOptionPane

import javax.swing.*; 
import java.awt.*; 
import java.awt.event.*; 

public class ClosingFrame extends JFrame { 

    private JMenuBar MenuBar = new JMenuBar(); 
    private JFrame frame = new JFrame(); 
    private static final long serialVersionUID = 1L; 
    private JMenu File = new JMenu("File"); 
    private JMenuItem Exit = new JMenuItem("Exit"); 
    private JFrame frame1 = new JFrame(); 

    public ClosingFrame() { 
     File.add(Exit); 
     MenuBar.add(File); 
     Exit.addActionListener(new ExitListener()); 
     WindowListener exitListener = new WindowAdapter() { 

      @Override 
      public void windowClosing(WindowEvent e) { 
       int confirm = JOptionPane.showOptionDialog(frame, 
         "Are You Sure to Close this Application?", 
         "Exit Confirmation", JOptionPane.YES_NO_OPTION, 
         JOptionPane.QUESTION_MESSAGE, null, null, null); 
       if (confirm == 0) { 
        System.exit(1); 
       } 
      } 
     }; 
     frame.addWindowListener(exitListener); 
     frame.setDefaultCloseOperation(EXIT_ON_CLOSE); 
     frame.setJMenuBar(MenuBar); 
     frame.setPreferredSize(new Dimension(400, 300)); 
     frame.setLocation(100, 100); 
     frame.pack(); 
     frame.setVisible(true); 

     frame1.addWindowListener(exitListener); 
     frame1.setDefaultCloseOperation(EXIT_ON_CLOSE); 
     frame1.setPreferredSize(new Dimension(400, 300)); 
     frame1.setLocation(500, 100); 
     frame1.pack(); 
     frame1.setVisible(true); 
    } 

    private class ExitListener implements ActionListener { 

     @Override 
     public void actionPerformed(ActionEvent e) { 
      int confirm = JOptionPane.showOptionDialog(frame, 
        "Are You Sure to Close this Application?", 
        "Exit Confirmation", JOptionPane.YES_NO_OPTION, 
        JOptionPane.QUESTION_MESSAGE, null, null, null); 
      JOptionPane.showMessageDialog(null, "Whatever", "Whatever", 
        JOptionPane.ERROR_MESSAGE); 
      int confirm1 = JOptionPane.showOptionDialog(frame1, 
        "Are You Sure to Close this Application?", 
        "Exit Confirmation", JOptionPane.YES_NO_OPTION, 
        JOptionPane.QUESTION_MESSAGE, null, null, null); 
      if (confirm == 0) { 
       //System.exit(1); 
      } 
     } 
    } 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 

      @Override 
      public void run() { 
       ClosingFrame cf = new ClosingFrame(); 
      } 
     }); 
    } 
}

对不起，我不明白你的问题很好，你的意思是你想从另外一个关闭一个JOptionPane的？

import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 

import javax.swing.JButton; 
import javax.swing.JFrame; 
import javax.swing.JOptionPane; 
import javax.swing.JPanel; 

public class GUIProgram extends JFrame implements ActionListener 
{ 
    private JButton btn1, btn2, btn3; 
    private static final String BUTTON1_COMMAND = "Press it!"; 
    private static final String BUTTON2_COMMAND = "show new JOptionPane!"; 
    private static final String BUTTON3_COMMAND = "close old JOptionPane!"; 
    private JOptionPane pane1, pane2; 

    public GUIProgram() 
    { 
     super("The title"); 
     setDefaultCloseOperation(EXIT_ON_CLOSE); 

     btn1 = new JButton(BUTTON1_COMMAND); 
     btn1.addActionListener(this); 
     btn1.setActionCommand(BUTTON1_COMMAND); 

     btn2 = new JButton(BUTTON2_COMMAND); 
     btn2.addActionListener(this); 
     btn2.setActionCommand(BUTTON2_COMMAND); 

     btn3 = new JButton(BUTTON3_COMMAND); 
     btn3.addActionListener(this); 
     btn3.setActionCommand(BUTTON3_COMMAND); 

     pane1 = new JOptionPane(); 
     pane2 = new JOptionPane(); 

     getContentPane().add(btn1); 
     setSize(200, 100); 
     setVisible(true); 
    } 

    public static void main(String args[]) 
    { 
     new GUIProgram(); 
    } 

    @Override 
    public void actionPerformed(ActionEvent e) 
    { 
     if(e.getActionCommand().equals(BUTTON1_COMMAND)) 
     { 
      JPanel panel = new JPanel(); 
      panel.add(btn2); 
      pane1.showOptionDialog(null, panel, "JOptionPane #1", JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, new Object[]{}, null); 
     } 

     else if(e.getActionCommand().equals(BUTTON2_COMMAND)) 
     { 
      JPanel panel = new JPanel(); 
      panel.add(btn3); 
      pane2.showOptionDialog(null, panel, "JOptionPane #2", JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, new Object[]{}, null); 
     } 

     else if(e.getActionCommand().equals(BUTTON3_COMMAND)) 
     { 
      pane1.getRootFrame().dispose(); 
     } 
    } 
}
