JOptionPane Passing Custom Buttons

Question

I\'m trying to get the value returned by custom buttons passed to JOptionPane. However the buttons I pass don\'t return a value at all. Only when the exit button is pressed

If you need this complex behavior, consider creating your own JDialog and then displaying it in a modal fashion.

If you have to use a JOptionPane, you can do this by extracting its JDialog and recursively iterating through its components til you find the one you want to disable and disable it:

import java.awt.Component;
import java.awt.Container;
import javax.swing.*;

public class Foo2 {
   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            doRun();
         }
      });
   }

   public static void doRun() {
      String[] options = {"Button 1", "Button 2", "Button 3"};

      JOptionPane myOptionPane = new JOptionPane("Heres a test message",
            JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION, 
            null, options, options[2]);
      JDialog myDialog = myOptionPane.createDialog(null, "My Test");
      myDialog.setModal(true);

      inactivateOption(myDialog, options[1]);

      myDialog.setVisible(true);
      Object result = myOptionPane.getValue();
      // Note: result might be null if the option is cancelled
      System.out.println("result: " + result);

      System.exit(0); // to stop Swing event thread
   }

   private static void inactivateOption(Container container, String text) {
      Component[] comps = container.getComponents();
      for (Component comp : comps) {
         if (comp instanceof AbstractButton) {
            AbstractButton btn = (AbstractButton) comp;
            if (btn.getActionCommand().equals(text)) {
               btn.setEnabled(false);
               return;
            }
         } else if (comp instanceof Container) {
            inactivateOption((Container) comp, text);
         }
      }

   }
}

However for myself, I'd just create a JDialog.
