JOptionPane button keyevents

how do i enable the buttons to respsond to key presses?
here's my Yes_No dialog to the user when he wants to quit the prog. buttons respond on clicking but there's no key event associated. How can i associate key presses with the buttons?
final JOptionPane optionPane = new
     JOptionPane("Are you sure you want to quit?",
        JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION);
     final JDialog dialog = new JDialog(this, "Exit", true);
     dialog.setContentPane(optionPane);
     dialog.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
     optionPane.addPropertyChangeListener(new PropertyChangeListener() {
     public void propertyChange(PropertyChangeEvent e)
          String prop = e.getPropertyName();
          if (dialog.isVisible() && (e.getSource() == optionPane) && (prop.equals(JOptionPane.VALUE_PROPERTY) || prop.equals(JOptionPane.INPUT_VALUE_PROPERTY)))
                     dialog.setVisible(false);
     dialog.pack();
     dialog.setLocationRelativeTo(null);
     dialog.setVisible(true);
     int result = ((Integer)optionPane.getValue()).intValue();
     if (result == JOptionPane.YES_OPTION)
          System.exit(0);
     else
          System.out.println("User decided not to quit.");

hi,
JOptionPane seems to have a keylistener, you could use that to detect key events, extend the JOptionPane class, making your own JOptionPane and use the listener to detect the key you want and handle the event.

JOptionPane buttons in English and in another language?

How do I change the language of the buttons in JOptionPane.showInputDialog?
When I use the Traditional Chinese Windows, I see Chinese characters in the buttons.
Can I have buttons in English even if I use the Traditional Chinese Windows? How? What web pages should I consult?
Locale locale = Locale.getDefault();
    locale = new Locale("en", "US");
    Locale.setDefault(locale);does not help me to get the correct human language I prefer, e.g. on the confirm button.
Edited by: tse2009 on Sep 12, 2009 6:22 AM

Finally, I searched the web and got some ideas from:
[http://jackywu1978.javaeye.com/blog/forum/97|http://jackywu1978.javaeye.com/blog/forum/97]
Then, I can get the preferred language on the buttons on JOptionPane.
import sun.awt.AppContext;
public class getTheRightLanguagePreferred{
Locale locale = Locale.getDefault();
    locale = new Locale("en", "US");
    Locale.setDefault(locale);
AppContext.getAppContext().put("JComponent.defaultLocale", locale);
}If you think that it is useful, please comment.

Mnemonics in JOptionPane buttons??

ive looked wround the api but i find no method that allows to add mnemonics to the default buttons that u can get when having a JOptionPane dialog box popup.
does anyone knowhow to add mnemonics to these buttons?
normally u would say button.setMnemonic(KeyEvent.VK_X)... but these buttons dont have a variable associated with them.
help please!

Hi... it may seem that I'm stating the obvious, but the JOptionPane classes are designed as a quick and dirty convenience method. There exist options to create your own buttons and pass them to the JOptionPane dialog constructor(s), which you should do to solve your problem. :-/

JOptionPane button renaming

Hi guys!
Had loadsa help with my last post, and I really appreciate it! But I call upon you once again!
Finishing touches, and I wanna remname the buttons in a JOptionPane message box.
I want a message to pop up and state the message "Welcome! Click 'next' to continue"
and for it to have two buttons, saying NEXT and QUIT. Have been rolling around the APIs, but can't see a thing that'll help me. Got some nice tips like renaming the title of the window a.s.o., but no button renaming options!
Really appreciate the help... !
:)

     JOptionPane op = new JOptionPane();
     String s = "Welcome! Click 'next' to continue";
     Object[]    bt = {"NEXT","QUIT"};
     op.showOptionDialog(null,s, "",op.YES_NO_OPTION,
                    op.QUESTION_MESSAGE, null, bt,bt[0]);      Noah

How to Handle Events for JOptionPane buttons?

Hi All,
I need a help...
I am trying to develop a simple SWING application that consists of multiple elements (mainly text fields) and a Submit button. On pressing Submit button, it should validate all the fields and then do something else. But if some fields are left blank, then it should give a pop-up message and on clicking the OK button on the pop-up message, the focus should go to that text field which is left null.
The problem is I am not able to understand how to Capture this OK button click-event of the pop-up message. I mean how to do something when the OK/Cancle button of the pop-up window is clicked.
Please Help me.
Thanks in Advance,
Ujjal

As already pointed out, JOptionPane has some static methods which show a dialog, and return an int, or a string. The whole point of this class is to remove the need for any event handling by the developer, that is, you simply call the showDialog method or whatever, and it returns a value telling you, for example, which button was pressed - no need for action listeners at all. The result of the showDialog method (or whichever you use) tells you which button was pressed. Check the javadocs for JOptionPane for details of several constants that indicate which button was pressed
The class exists to make simple dialogs trivial to generate - you're overcomplicating things!

Change Button Name in JOptionPane.showMessageDialog

Hello,
I've written the following code that invokes a JOPtionPane messageDialog, when the delete button is hit in the following frame and the selectedItem in the JComboBox is Default.
I want to change the JOPtionPane button name from OK to Close. Is there a way to do this with error message dialoges, as their is with confirmDialoges?
Please help out.

Hi,
yes, I've looked at the tutorials. But there is no way to change button title for JOptionPane.showMessageDialog. Only JOptionPane.showOptionsDialog provides you w/ that feature, becuz it provides the parameter in the method.
I was wondering if there was another way to do this for showMessageDialog.

JOptionPane and JDialog.DO_NOTHING_ON_CLOSE broken?

Hi there
I've created a JDialog from a JOptionPane and I don't want the user to simply dispose of the dialog by clicking on the close button but they are still able and I'm sure that my code is correct. Is it my code that is wrong or is it a java bug? Oh I'm running on 1.3 BTW
JFrame f = new JFrame();
f.setSize(500, 500);
f.setVisible(true);
JOptionPane optionPane = new JOptionPane("Hello there", JOptionPane.INFORMATION_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
JDialog d = optionPane.createDialog(f, "Testing");
d.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
d.setVisible(true);I know that I can just set up a JDialog directly and use the setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE) and it seems to work properly but I would like to see it work for JOptionPane!
Thanks in advance

Sorry but this doesn't make it work either. I've looked at the code for createDialog in JOptionPane and it actually adds a WindowListener to the dialog in there as well as a propertyListener. On closing the option pane it calls a method in windowClosing of the windowListener which in turn fires a property change event which then tells the dialog to dispose itself so the addition of another windowAdapter to override the windowClosing method will not help :-(
I've managed to get round it by doing something similar to
JFrame frame = new JFrame();
final JDialog dialog = new JDialog(frame, "Testing", true);
JButton button = new JButton("OK");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
dialog.dispose();
JOptionPane optionPane = new JOptionPane(button, JOptionPane.INFORMATION_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
dialog.setContentPane(optionPane);
dialog.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
dialog.pack();
dialog.setVisible(true);

JOptionPane JButton Icon

Hi,
Does anyone knows how to set icons in the JOptionPane buttons ?
I use this but when I click it never closes the dialog.
JButton[] options = new JButton[3];
options[0] = new JButton("B1");
options[1] = new JButton("B2");
options[2] = new JButton("B3");
int n = JOptionPane.showOptionDialog(null,
"Would you like to replace it ?",
"Question",
JOptionPane.YES_NO_CANCEL_OPTION,
JOptionPane.QUESTION_MESSAGE,
null,
options,
null);
System.out.println(n);
Thanks.

Use this :
Icon[] options = { new ImageIcon("yes.gif"),new ImageIcon("no.gif"), new ImageIcon("cancel.gif")};
int res = JOptionPane.showOptionDialog(null, "Select a button", "title", JOptionPane.DEFAULT_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[0]);I hope this helps,

Key-enable buttons on a JOptionPane

Hi,
The existing code in my Application uses a JOptionPane static method = JOptionPane.showOptionDialog() to create a dialog box.Is there any way I can key-enable the buttons on the dialog created by this method.
public int createAndShowGUI() {
if (!issuesPanel.hasIssues())
return -2; //TODO make constant
else {
//Custom button text
String[] options = should_continue ? new String[] {returnText, continueText} : new String[] {returnText};
int optionButtons = should_continue ? JOptionPane.OK_CANCEL_OPTION : JOptionPane.CANCEL_OPTION ;
log.info("IssuesOptionPane displayed - " + title);
int optionChosen = JOptionPane.showOptionDialog(parent,
issuesPanel.createAndGetIssuesPanel(),
title,
optionButtons,
JOptionPane.PLAIN_MESSAGE,
null, //don't use a custom icon
options, //titles of buttons
null); //no default selected button
String buttontext = optionChosen == CLOSE ? "X" : options[optionChosen];
log.info("User clicked on the " + buttontext + " button");
return optionChosen;
I see that there is no way to get a handle on the JButtons created by the JOptionPane.So, one work around that I tried is to create a JPanel, add JButtons , set Input Map, set Action Map ( to add key bindings ) on it.Then create a JDialog and pass this JPanel to the dialog using setContentPane
     private static void createAndShowGUI(){
          JButton bookingButton=new JButton(bookStr);
          JButton returnButton=new JButton(returnStr);
          bookingButton.addActionListener(new BookAction());
          returnButton.addActionListener(new ReturnAction());
          JPanel panel=new JPanel();
          panel.add(bookingButton);
          panel.add(returnButton);
          panel.setActionMap(initActionMap());
          initAndSetInputMap(panel);
          JDialog dialog=new JDialog();
          dialog.setSize(400,100);
          dialog.setModal(true);
          dialog.setContentPane(panel);
          dialog.addPropertyChangeListener(indicator,listener);
          System.out.println("step 1" );
          dialog.pack();
          System.out.println("step 2");
          dialog.setVisible(true);
But the problem that I am facing here is that the property change events triggered by the code inside the actionPerformed methods is not getting capturesd by the listener attached to the JDialog.
Any thoughts?
Thanks
Aman

JoptionPane need some help understanding, with buttons PLEASE SOMEONE :)

Hi all I was hoping that someone would be kind enough to explain to me how I can add a method to buttons in a JoptionPane.
Also can I pplease ask for you to look at this code I think I have stuff something as it is not working the way that I want,
I want to add something like this to the ok button.
String check = LastNameJText.getText()+FirstNameJText.getText();
System.out.println(check);
      if
        //check to see if First & Last name have been entered.
        (check != null){
        return;
        else //create a dialog that shows Title,first & Last Name
         // & ask if you would like to make an new ordre
          String d= System.getProperty("line.separator");
       Object[] options = {"Cancel","OK",};
       int n = JOptionPane.showOptionDialog(null,
       "Do you really want to add a new shoe order for:"+ d +
       (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+" "+LastNameJText.getText(),"New Order",
       JOptionPane.YES_OPTION,
       JOptionPane.INFORMATION_MESSAGE,
       null,
       options,
    options[0]);
      if //Check to see if First & Last name text feilds are clear.
(check == null){
return ;
else
   //make sure that all text fields are clear for new order
        ClearAllTextFields();

When I do that i get
"Order.java": Error #: 300 : variable options not found in class epod_1_0.Order at line 2152, column 4
"Order.java": Error #: 300 : variable options not found in class epod_1_0.Order at line 2153, column 4
why would this be ?
This is the code
String check = LastNameJText.getText()+FirstNameJText.getText();
System.out.println(check);
      if
        //check to see if First & Last name have been entered.
        (check != null){
        return;
        else //create a dialog that shows Title,first & Last Name
         // & ask if you would like to make an new ordre
          String d= System.getProperty("line.separator");
      int result = JOptionPane.showOptionDialog(null,
   "Do you really want to add a new shoe order for:"+ d +
   (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+
    " "+LastNameJText.getText(),"New Order",
   JOptionPane.YES_OPTION,
   JOptionPane.INFORMATION_MESSAGE,
   null,
   options,
   options[0]);
switch(result){
   case JOptionPane.YES_OPTION: // Add your code for yes
      break;
   case JOptionPane.NO_OPTION: // Add your code for no
     dispose();
      break;
      if //Check to see if First & Last name text feilds are clear.
(check == null){
return ;
else
   //make sure that all text fields are clear for new order
        ClearAllTextFields();
}

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 custom buttons to JOptionPane

Hi,
I need to add custom buttons to my showMessageDialogue boxes.
I know that
JOptionPane.showMessageDialog
(null, "message body", "message title", JOptionPane.YES_NO_OPTION,
JOptionPane.INFORMATION_MESSAGE);displays an information box with a 'Yes' and a 'No' button. But how do I include three or more custom buttons on such a box?
For example, I want to display an information message box with buttons: 'Auto', 'Prompt' and 'Never'.
What if I want to mix orthodox buttons, with my custom buttons? For example, putting 'Auto', 'Prompt' and 'Cancel' in one information message box?
Thanks,
Hasanka.

Use the last method for showMessageDialog. The options[] paremeter can take an array of Strings and return to you which button was pressed (by index).
showOptionDialog
public static int showOptionDialog(Component parentComponent,
                                   Object message,
                                   String title,
                                   int optionType,
                                   int messageType,
                                   Icon icon,
                                   Object[] options,
                                   Object initialValue)Brings up a modal dialog with a specified icon, where the initial choice is dermined by the initialValue parameter and the number of choices is determined by the optionType parameter.
If optionType is YES_NO_OPTION, or YES_NO_CANCEL_OPTION and the options parameter is null, then the options are supplied by the Look and Feel.
The messageType parameter is primarily used to supply a default icon from the Look and Feel.
Parameters:
parentComponent - determines the Frame in which the dialog is displayed; if null, or if the parentComponent has no Frame, a default Frame is used
message - the Object to display
title - the title string for the dialog
optionType - an integer designating the options available on the dialog: YES_NO_OPTION, or YES_NO_CANCEL_OPTION
messageType - an integer designating the kind of message this is, primarily used to determine the icon from the pluggable Look and Feel: ERROR_MESSAGE, INFORMATION_MESSAGE, WARNING_MESSAGE, QUESTION_MESSAGE, or PLAIN_MESSAGE
icon - the icon to display in the dialog
options - an array of objects indicating the possible choices the user can make; if the objects are components, they are rendered properly; non-String objects are rendered using their toString methods; if this parameter is null, the options are determined by the Look and Feel.
initialValue - the object that represents the default selection for the dialog
Returns:
an integer indicating the option chosen by the user, or CLOSED_OPTION if the user closed the Dialog

Keystrokes for button actions in JOptionPane

When running my app in Windows, the Alt key must be pressed to cause the "Yes" button or "No" button to respond from the keyboard. Can I set an option in JOptionPane, or elsewhere, to not require pressing the Alt key to activate a button in JOptionPane?

Help Button in JOptionPane

Hi all,
is there any easy way to provide a (possible locale sensitive) Help Button in JOptionPane Dialogs? Are there any libs that extend the Standard Dialogs to provide such a button?
Many thanks for your ideas!
bye
Marcus

This guy made his own alternative OptionPane that has such a feature:
