ActionListener for JOptionPane.showConfirmDialog

Is it possible to handle JOptionPane.showConfirmDailog 's button click events through action listeners?
I want to execute some code on the "Save" button click and want to do it like my JFileChooser window stays in the background until either of the Yes,No or Cancel buttons of the showConfirmDialog is pressed.In fact I'm able to get the state of the button pressed using,
int i=JOptionPane.showConfirmDialog(null,"Confirm file overwrite?")but can't make the showConfirmDialog window stay in the background,,,
Can anybody please help?
Thanks in advance...

There are forums specifically for GUI questions.
I believe there is also a forum for international issues.

Tooltip for a JOptionPane.showConfirmDialog??

I can't get this to work, any ideas on how to reference the OK & Cancel buttons of the "JOptionPane.showConfirmDialog" and create a custom tooltip for each??
// --------- test to see if the current file was modified and give an option to save first.
if (changed)
// ----- display pop-up alert --------------------------------------------------------------
int confirm = JOptionPane.showConfirmDialog(null,
"Click OK to discard current changes, \n or Cancel to save before proceeding.", // msg
"Unsaved Modifications!", // title
JOptionPane.OK_CANCEL_OPTION, // buttons displayed
                    // JOptionPane.ERROR_MESSAGE
                    // JOptionPane.INFORMATION_MESSAGE
                    // JOptionPane.PLAIN_MESSAGE
                    // JOptionPane.QUESTION_MESSAGE
JOptionPane.WARNING_MESSAGE,
null);
// -- set the tool tip for the buttons here -- ??????
// public Point getToolTipLocation( MouseEvent event);
// public JToolTip createToolTip( );
// toolTipText
// Point getToolTipLocation( MouseEvent MOUSE_CLICKED);
JOptionPane.getToolTipLocation(OK_OPTION, Click to discard current changes."")
// OKButton.setToolTipText("Click to discard current changes.");
// CancelButton.setToolTipText("Click to save the current file.");
if (confirm != JOptionPane.YES_OPTION)
{ //user wants to save changes
try {
// save the file
catch(Exception e) {}
} // close "if (changed)"
// ----- display pop-up alert --------------------------------------------------------------

The renderer code has this structure:

          if (data instanceof MyDataObject) {
               MyDataObject myObj = (MyDataObject)data;
               JLabel label = new JLabel();
               label.setIcon(myObj.getIcon());
               label.setText(myObj.getInfo());
               label.setToolTipText("MyTooltip");

JOptionPane.showConfirmDialog requires two key strokes with Java SE 6.

I have been using the following line of code:
rc = JOptionPane.showConfirmDialog( comp, objects, "Warning",
JOptionPane.YES_NO_OPTION,
JOptionPane.INFORMATION_MESSAGE);
with no problems with plug-in 1.4 and 1.5. Now with 1.6, when I choose Yes/No/Cancel, the first time I press the button nothing happens, the second time I press the button the action takes place.
I have been searching for information on this and have not found any known issues (yet). Does anyone have any ideas?

further investigation shows that this only happens when the component is a JComboBox. I found a new bug that seems to be the same issue:
http://bugs.sun.com./bugdatabase/view_bug.do?bug_id=6817939
When calling JOptionPane.showConfirmDialog from an ActionListener called by a JComboBox, there is 2 issues:
* the focus is not given to the confirm dialog

Problem w/JOptionPane showConfirmDialog

Okay, I have a JOptionPane.showConfirmDialog on a JInternalFrame that works for the most part, but is doing something weird. When a user clicks the Cancel option or closes the JOptionPane, I want it simply to go away. Instead, it will pop up again, and if the user click Cancel or closes the window, it will go away, but it will take the JInternalFrame with it, which I don't want it to do. I have the code pasted below, and it should work the way I have it coded, but it don't. Anyone help??int result = JOptionPane.showConfirmDialog(CustomFrame.this, getTitle() +
   " has been changed. Would you like to save?", "Save File?", JOptionPane.YES_NO_CANCEL_OPTION,
   JOptionPane.WARNING_MESSAGE);
   switch(result)
      default:
         break;
      case JOptionPane.YES_OPTION:
         save();
         break;
      case JOptionPane.NO_OPTION:
         dispose();
         break;
      case JOptionPane.CANCEL_OPTION:
         break;
   }Now this is being triggered from the internalFrameClosing method of the InternalFrameListener interface that is implemented on a private class in my JInternalFrame constructor. And like I said, all other aspects of it work fine and when it's supposed to, but with the Cancel option or closing the JOptionPane (which would trigger the default: option from the switch construct, correct?), I want it to go away. It will pop up a second time, then go away with the JInternalFrame. Any suggestions? Thanks a lot. I'm using JDK 1.4.1 for the Macintosh (15" iMac G4).

JOptionPane showConfirmDialog problem

Hello everyone,
I have written my own class that shows a customized confirm dialog (code is pasted below). I need to be able to tell whether the user clicks "YES", "NO" or "CANCEL".
My main app has a panel with a JButton "Start System". When this button is clicked, the following code instantiates OperatorConfirmDialog:
     public void startNetwork(){
          confirmDialog = new OperatorConfirmDialog("Are you sure you want to start the network?");
          System.out.println("WE MADE IT TO HERE");//problem we do not get to here until confirm dialog acked
     }I referred to the examples for JOptionPane given at:
http://java.sun.com/j2se/1.5.0/docs/api/index.html
for examples but it doesn't seem to be working for me.
Here is the code for OperatorConfirmDialog
public class OperatorConfirmDialog extends JFrame {
     JOptionPane pane;
     public OperatorConfirmDialog(String message){
          pane = new JOptionPane();
          this.setDefaultLookAndFeelDecorated(true);
          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          this.getContentPane().setLayout(new BorderLayout());
          pack();
          //pane.getSelectionValues()
          pane.showConfirmDialog(this, message, "Confirm", JOptionPane.YES_NO_CANCEL_OPTION);
          Object selectedValue = pane.getValue(); //problem here
          if(selectedValue == null){
               //do nothing...they just killed window
          }else {
               for(int counter = 0, maxCounter = pane.getOptions().length; counter < maxCounter; counter++){
                    if(pane.getOptions()[counter].equals(selectedValue)){
                         //do something
          this.dispose();
     public JOptionPane getPane(){
          return pane;
     public static void main(String[] args) {
          OperatorConfirmDialog dialog = new OperatorConfirmDialog("Please enter a valid username.");
}I put a break point at the line:
if(selectedValue == null){
When I run the debugger, confirmDialog prompts me to click "YES", "NO" or "CANCEL". I click "YES" and then arrive at the breakpoint. But, selectedValue doesn't seem to have the right value....the debugger says its value is "uninitializedValue" (literally). Any ideas?
Thanks!

Try this. Notice I received an int result from the showConfirmDialog() method.
import javax.swing.*;
import java.awt.*;
public class OperatorConfirmDialog extends JFrame {
    JOptionPane pane;
    public OperatorConfirmDialog(String message) {
        pane = new JOptionPane();
        this.setDefaultLookAndFeelDecorated(true);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.getContentPane().setLayout(new BorderLayout());
        pack();
// get the response from the user
        int result = pane.showConfirmDialog(this, message, "Confirm", JOptionPane.YES_NO_CANCEL_OPTION);
        if (JOptionPane.YES_OPTION == result) {
            // do what you want on 'yes' clicked
            System.out.println("User Clicked 'Yes'.");
        } else {
// user clicked 'no' or 'cancel'... you could check result for JOptionPane.NO_OPTION or CANCEL_OPTION
            System.out.println("User Clicked either 'No' or 'Cancel'.");
        this.dispose();
    public JOptionPane getPane() {
        return pane;
    public static void main(String[] args) {
        OperatorConfirmDialog dialog = new OperatorConfirmDialog("Please enter a valid username.");
}

JOptionPane.showConfirmDialog -- remember decision checkbox

Hi
JOptionPane.showConfirmDialog -- remember decision checkbox
is there something to set "remember my decision" for the following dialog box i.e. this dialog sits inside a loop over a set of files
so if i say "yes overwrite" it should remember that decision. Should i make a dialog box on my own or is there a parameter setting for this
purpose ?
if(currentCsvOutputFile.isFile()){
int userConfirm = JOptionPane.showConfirmDialog(
          new JFrame(),
          currentCsvOutputFile + " already exists , Do you want to overwrite it ? " ,
          "Confirm",
          JOptionPane.YES_NO_OPTION);
}Regards

No need for a custom dialog, just add a JLabel and a JCheckBox to a JPanel and pass that as the message parameter.JCheckBox remember = new JCheckBox("Remember my decision");
    JPanel panel = new JPanel(new BorderLayout()); // or whatever layout you find best
    panel.add(new JLabel("File already exists , Do you want to overwrite it ? "), BorderLayout.NORTH);
    anel.add(remember, BorderLayout.SOUTH);
    int userConfirm = JOptionPane.showConfirmDialog(new JFrame(), panel, "Confirm", JOptionPane.YES_NO_OPTION);db

JOptionPane.showConfirmDialog "NO" button acting as "YES" on MAC using TAB

JOptionPane.showConfirmDialog "NO" button acting as "YES" on MAC using TAB

Ya , I am asking question ? Why "NO" is acting as "YES" button in case of JOptionPane.showConfirmDialog on MAC using TAB.
i.e,
I clicked on some button, then showConfirmDialog is opened, By default the focus is on "YES" button. Now I pressed TAB button and changed to the focus to "NO" button.
If press ENTER key --> acting "YES"
If press SPACE key -> acting as "NO"
Why ?
What should I do to make it correct ?
Am I need mention set (Key,value) pairs for UIManager in case of MAC.
Please suggest ?

Adding actionListener to JOptionPane

how do you add an actionListener to a JOptionPane?
im using JOptionPane.showMessageDialog, and i want an event to happen when the user clicks on the "Okay" button

Can you do something like this instead? Use a showConfirmDialog(...) istead of the showMessageDialog(...), then use the return value to determine which button the user pushed?
int retValue = JOptionPane.showConfirmDialog(parent, message, Title, JOptionPane.OK_CANCEL_OPTION );
if (retValue == JOptionPane.OK_OPTION)
doOkayEvent();
else
doNotOkayEvent();

JOptionPane.showConfirmDialog in servlets

Hi
I am trying to show a dialog in a doPost method of a servlet. For some reason, it blocks the entire method and does not show the dialog. What gets me voiceless is that it works in the doGet method of the servlet.
The situation is the following:
- a first serlvet dispatches GET requests to other servlets according to the role of users.
- in the doGet of this first servlet, a second (servlet2) is instantiated and its doGet is called;
- in the doGet of servlet2, a HTML form (POST method) is generated;
- when the submit button of the HTML form is pressed, the form is processed by the doPost of servlet2.
JOptionPane.showConfirmDialog works in servlet2 only in the doGet and not in the doPost. Their code is:
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
DataModule1 dm = (DataModule1) ixPageProducer1.getSessionDataModule(request.getSession());
dm.parameterRow1.setString("empl_ini", request.getRemoteUser());
dm.queryDataSet1.refresh();
empl_id = dm.queryDataSet1.getInt("number");
ixPageProducer1.servletGet(this, request, response);
//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
DataModule1 dm = (DataModule1) ixPageProducer1.getSessionDataModule(request.getSession());
dm.queryDataSetReq.insertRow(false);
ixPageProducer1.servletPost(this, request, response);
JOptionPane.showConfirmDialog(null, "test" , "Request Confirmation", JOptionPane.YES_NO_OPTION);
(I am using JBuilder and its InternetBeans to link the HTML pages with the DB).
Many thanks in advance for helping a desperate Java beginner!!!

I figured out that the dialog was actually generated, but "behind" my browser.You can try this to add the following either before or after the JOptionPane.showConfirmDialog:
JOptionPane.requestFocus();
But I think your best bet is to associate a frame with your dialog box as follows:
Object parent = this.getParent();
while (!(parent instanceof Frame)) parent = ((Component)parent).getParent();
F = (Frame)parent;
JOptionPane.showConfirmDialog(F, "test" , "Request Confirmation", JOptionPane.YES_NO_OPTION);
If this helps, don't forget the Dukes

Can we add scrollbar to JOptionPane.showConfirmDialog()

Hi,
Can we add a scroll bar to JOptionPane.showConfirmDialog() so that the contents(messages) which are to be displayed are present in scrollbar so that the buttons will be visible to the user like OK, CANCEL.
Currently when the message is large the buttons will not be visble in the screen.
So, it is possible ? Or there is any other alternative for the same.
Thanks.

Is there another library that I have to import? I recieve this error when I try to compile...
isPrime.java:53: cannot find symbol
symbol : variable sb
location: class isPrime
     JTextArea area = new JTextArea(sb.toString() );
I have javax.swing.* imported as of right now...
     JTextArea area = new JTextArea(sb.toString());
      area.setRows(25);
      area.setColumns(100);
      area.setLineWrap(true);
      JScrollPane pane = new JScrollPane(area);
       JOptionPane.showConfirmDialog(null,
     pane,
       "Test", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);
/*         JOptionPane.showMessageDialog(null,
           printArray(array),
     "Thanks for using Reverse Array", JOptionPane.INFORMATION_MESSAGE);
*/       the comment text is what I eventually wish to print((I simply hid it from the compiler so I could play w/ the code you provided)... it is the first 'n' number of primes up to which I'd like to be able to scroll through for large prints over 100 primes.
thx for the help

WindowsClosingEvent on JOptionPane.showConfirmDialog

I have a confirmdialog but i want to be able to control what happens when i close this window instead of pressing yes or no.
I have been reading about WindowListeners. Ive imlpemented WindowListener but i dont know how to add the windowListener to my confirmDialog.
Heres the method i use for creating a confirmdialog
private boolean confirmDialogue(String message) {
        int selectedOption = JOptionPane.showConfirmDialog(this, message, "Confirmation", JOptionPane.YES_NO_OPTION, JOptionPane.WARNING_MESSAGE);
        return (selectedOption == JOptionPane.YES_OPTION);
    }

Okay, I could do it like this but im not sure if its the best way:
private boolean confirmDialogue(String message) {
        int selectedOption = JOptionPane.showConfirmDialog(this, message, "Confirmation", JOptionPane.YES_NO_OPTION, JOptionPane.WARNING_MESSAGE);
        if(selectedOption == JOptionPane.CLOSED_OPTION)
            System.out.println("CLOSED WINDOW");
        return (selectedOption == JOptionPane.YES_OPTION);
    }

About JOptionPane.showConfirmDialog

If i have this code :
public class XFrame extends JFrame {
    private static class ExitListener extends WindowAdapter {
        int confirm = JOptionPane.showConfirmDialog(null, .......);
    public XFrame() {
        setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);
        addWindowListener(new ExitListener());
}The confirm dialog box showed in the center of screen, not in the center of XFrame instance.
So if my screen size is bigger than XFrame size, and XFrame does not located in the center, it seems a little ugly for me.
What should I do?. It is impossible to write :
int confirm = JOptionPane.showConfirmDialog(this, ....) since this will refer to inner class (ExitListener), not the XFrame class. What is the correct syntax to center the confirm dialog?

Hi this should do what you want
public class Test extends JFrame {
public Test() {
    this.setSize(600,600);
    setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);
    this.show();
    final Test test = this;
    addWindowListener(new WindowAdapter() {
      int confirm = JOptionPane.showConfirmDialog(test,"Some info");
public static void main(String[] args) {
    Test testApp = new Test();
}

How to create a actionListener for individual JButton in a for loop?

How to create a actionListener for individual JButton in a for loop? Can someone help me?

Do you mean something like this?:

     tempButton = new JButton("Button " + String.valueOf(i));
     tempButton.setActionCommand("action" + String.valueOf(i));

JOptionPane.showConfirmDialog: Tabbing between options creates wrong result

In JOptionPane.showConfirmDialog, when pressing <tab> to move between options and then pressing <Enter> I always get a returned zero (0) no matter which button is in focus. Is this a (known) bug or am I stupid?
I run the following code.
import javax.swing.*;
public class TabOptions
public static void main (String [] args)
     int n = JOptionPane.showConfirmDialog (null, "Use <Tab> to shift option-button, then press <Enter>. " +
                         "I'll write the returned value to sdt out.");
     System.out.println ("Returned value: " + n);
}

import javax.swing.*;
class TabOptions
public static void main (String [] args)
UIManager.put("Button.defaultButtonFollowsFocus", Boolean.TRUE);//<--------------------
int n = JOptionPane.showConfirmDialog (null, "Use <Tab> to shift option-button, then press <Enter>. " +
"I'll write the returned value to sdt out.");
System.out.println ("Returned value: " + n);
}
