Giving JTextField for JOptionPane.showInputDialog

Hi All,
For the above method
public static Object showInputDialog(Component parentComponent,
                                     Object message,
                                     String title,
                                     int messageType,

                              throws HeadlessExceptionBasically i am giving like this.
.Object[] selectionvalues={"gif","png","jpg","bmp","ico"};
JTextField jtf=new JTextField(15);How can i add the JtextField so that the text which i gave will take the extension of the object array variables given.
Any help appreciated..
Thanks in advance.

Argh, so now we are getting somewhere. ;o)
JOptionPane are usually used as a quick, simple way of presenting a dialogbox to the user. I don't think it will be suitable for what you want to do.
Have a look at this link: [http://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html|http://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html]
I think you will need to create a simple dialog box class to do this because the JOptionPane will close when you press the OK button so the user won't see your JTextField with the new value in it.
BTW, Here is a link for a tutorial that shows you how to customise the JOptionPane for more advanced topics:

Custom icon for JOptionPane.showInputDialog

As a novice who's wading through Deitel's 'Java how to program', using java2 and j2sdk1.4.1 on JCreator Pro. I want to use my own icons on a small proggie i've written. I know that the format is:
showInputDialog(Component parentComponent, Object message, String title, int messageType, Icon icon, Object[] selectionValues, Object initialSelectionValue)
however this doesn't tell me how to write the code. how do i change the default '?' icon for my own icon?
thanks for any help

JOptionPane.showInputDialog and Focus

I have a program that allows the user to type in a String in a text box and when they hit the enter key the text will appear in a text area. I've also added a menu bar to the program. When the user clicks on File and then Connect from the menu bar I want a JOptionPane to pop up that asks for the user to type in a username and then prompt for a password. And I've gotten all of that to work. Now for the problem. I click on file from the menu bar and then connect and it prompts me for the username as it should. I am able to just type in a phrase in the text field of the username dialog box and hit the enter key and then it prompts me for my password. I am still able to type in a phrase in the text field of the password Dialog box, however when I hit the enter key, the Dialog box does not close as it did for the username Dialog box. It will still close if I click on the OK button, but just pressing the enter key does not close the Dialog box as it did when it prompted for a username. I'm thinking I need to direct the focus to the password dialog box, but not sure how to go about doing this. Any help in solving this problem would be greatly appreciated.
Here is my code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class TestJOptionPane extends JFrame implements ActionListener{
     private static int borderwidth = 570;
     private static int borderheight = 500;
     private JPanel p1 = new JPanel();
     private JMenu m1 = new JMenu("File");
     private JMenuBar mb1 = new JMenuBar();
     private JTextArea ta1 = new JTextArea("");
     private JTextField tf1 =new JTextField();
     private Container pane;
     private static String s1, username, password;
     private JMenuItem [] mia1 = {new JMenuItem("Connect"),new JMenuItem("DisConnect"),
          new JMenuItem("New..."), new JMenuItem ("Open..."), new JMenuItem ("Save"),
          new JMenuItem ("Save As..."), new JMenuItem ("Exit")};
public TestJOptionPane (){
     pane = this.getContentPane();
          addWindowListener(new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
     dispose();
System.exit(0);
     setJMenuBar(mb1);
mb1.add(m1);
for(int j=0; j<mia1.length; j++){
     m1.add(mia1[j]);
p1.setLayout( new BorderLayout(0,0));
setSize(borderwidth, borderheight);
pane.add(p1);
          p1.add(tf1, BorderLayout.NORTH);
          p1.add(ta1, BorderLayout.CENTER);
          this.show();
          tf1.addActionListener(this);
          for(int j=0; j<mia1.length; j++){
               mia1[j].addActionListener(this);
     public void actionPerformed(ActionEvent e){
          Object source = e.getSource();
          if(source.equals(mia1 [0])){
               username = JOptionPane.showInputDialog(pane, "Username");
               password = JOptionPane.showInputDialog(pane, "Password");
          if(source.equals(tf1)){
               s1=tf1.getText();
               ta1.append(s1+"\n");
               s1="";
               tf1.setText("");
     public static void main(String args[]){
          TestJOptionPane test= new TestJOptionPane();
}

But using JOptionPane doesn't get the focus when you call itworks ok like this
import javax.swing.*;
import java.awt.event.*;
class Testing
public Testing()
    final JPasswordField pwd = new JPasswordField(10);
    ActionListener al = new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        pwd.requestFocusInWindow();}};
    javax.swing.Timer timer = new javax.swing.Timer(250,al);
    timer.setRepeats(false);
    timer.start();
    int action = JOptionPane.showConfirmDialog(null, pwd,"Enter Password",JOptionPane.OK_CANCEL_OPTION);
    if(action < 0)JOptionPane.showMessageDialog(null,"Cancel, X or escape key selected");
    else JOptionPane.showMessageDialog(null,"Your password is "+new String(pwd.getPassword()));
    System.exit(0);
public static void main(String args[]){new Testing();}
}

JOptionPane.showInputDialog

Hi,
I have a question about JOptionPane.showInputDialog(...), there is a method that accepts an object array for its parameter, when the array size exceeds a certain bound the final dialog will contains a JList in it. When I click the item of the JList then click cancel the null will be returned, but when double clicking item and then cancel the item will be returned. Partial of my code is:
String[] available = toSortedStringArray(mapColumn.keys());
if (available.length == 0)
     return;
Object selected =
     JOptionPane.showInputDialog(
          FilterControl.this,
          "Select Column",
JOptionPane.QUESTION_MESSAGE,
          null,
          available,
          null);
if (selected != null)
When the dialog shows, double click one of the items in the JList and then click cancel, the selected will be the item, that's what we unexpected, the null returned will be expected.
Who can help giving a hint about how to solve this problem?
PS: One of the solutions is don't call this static method but write our own code or to create a class to extend the JOptionPane, but I think it is ineffective.

It's a bug:

JOptionPane.showInputDialog Help!!!!

Hello,
I'm using JOptionPane.showInputDialog(Component parentComponent,
Object message,
String title,
int messageType,
Icon icon,
Object[] selectionValues,
Object initialSelectionValue ).
which prompts the user to add some text and the same will be stored for later retrieval.
In this case, JOptionPane pops up with a label, textfield,OK & Cancel buttons.
Default focus is given to to the TextField.
Is there anyway to get access to the TextField via code ?
For example, if the user types "Hello World" in the given TextField, then I need to get the Text entered in
the TextField in the following manner.
String myStr = myJOptionPaneTextField().getText();
System.out.println("Entered Text is "+ myStr);
How can I Achieve the same ?
Thanks in advance
Regards
vargav

Why? At what point do you know you should manipulate the text? Usually, it would be when the user clicks OK, at which point it doesn't matter because the dialog is dismissed. So what kind of operations do you expect to be able to do?
Aside from that, I'm not sure how to get the text field in the option pane, per se... It can be gotten by digging thru the pane's components til you find a text field. But you'd need to do that in a separate thread. So it's not really feasible to do that.... There is an alternative:
The message is an object, and it can be an array of objects, which will all be added, and thus can include a message string and a text field...
JTextField myfield = new JTextField();
Object[] obj = new Object[2];
obj[0] = "Enter some text here:";
obj[1] = myfield;
if(JOptionPane.showOptionDialog(obj, "Enter Text", JOptionPane.OK_CANCEL_OPTION) == JOptionPane.OK_OPTION) {
String value = myfield.getText();
}Then you can do whatever you want with the text field... but the same problem is there, you have lost the dialog before you can do anything.

Help with JOptionPane.showInputDialog

Hi!!
People here helped me before so trying my luck again:)
In order to get information from people I use JOptionPane.showInputdialog,
problem is if I need to get 2 different types of info I have to use
naam = JOptionPane.showInputDialog(null, "Geef speler naam:");
land = JOptionPane.showInputDialog(null, "Geef Land Speler:");Is there anyway to make this happen in 1 screen?
Or do I have to make a new frame for that with textfields and such?
if so, anyone got an example?

im new here:) so.. New to Java Technology suits me
well I guess.No it doesn't. New to Java forum is for classpath questions, simple compile time problems and lazy students to cross post their assigments into.
Swing questions, such as the one you asked, should be asked in the Swing forum because the people who answer questions in there are more knowledgeable about Swing. Plus you will almost 100% likely to find working example codes from previous posts in the Swing forum for Swing related questions.
Much more likely than in here anyway.

JOptionPane.showInputDialog cancel brings up a blank box

String name = JOptionPane.showInputDialog(
    null,
    "My message",
    "My title",
    null,
    null,
    null) // real list of options deleted for brevityThis works okay, but when I press the cancel button, I get a blank warning JOptionPane (message box thingy)... how do I tailor the message in that? Been looking through the search results and API with little luck.

handle it like so
try
    String s = new JOptionPane.showInputDialog(null, "Enter input");
catch(Exception ee)
    JOptionPane.showMessageDialog("Invalid input");
}

JOptionPane.showInputDialog error checking?

menu = JOptionPane.showInputDialog("What would you like to do next: \n" +
"1: Enter another person (" + (data.length - index - 1) + " entries left)\n" +
"2: Display data sorted by First Name\n" +
"3: Display data sorted by Last Name\n" +
"4: Display data sorted by Birth Date\n" +
"5: Search data by First Name\n" +
"6: Search data by Last Name\n" +
"7: Search data by Birth Date\n\n" +
"0: Exit");How can I error check that to make only those values will be entered. I thought I would be able to say something like, if(menu != "0") and so on, but that doesn't seem to work, neither does if(menu == null). Thanks in advance for any help, I am probably just doing something stupid.

Strange problem with JOptionPane.showInputDialog

I have a strange problem with JOptionPane.showInputDialog in that when I run a program anything that is typed in is displayed backwards, for example: I type this character > and this < is what is displayed.
I've uninstalled the sdk and reinstalled it twice but that hasn't solved my problem and the java plug-in in the control panel is displaying the same symptoms.
I did a search before posting this but all I got really was posts from people who wanted to reverse their text.
Thanks for your help on this.

Is it just the < and > characters?

Using JOptionPane.showInputDialog to return an integer

I am currently using JOptionPane to return a string from the Object array i made with all possible choices.
     private static boolean determineService(){
          JLabel label;
          label=new JLabel("Please select which Service Model to use.",JLabel.CENTER);
          Object[] possibilities = {"AddressCleanse", "VIN", "PostalCode"};
          serviceModel = (String)JOptionPane.showInputDialog(
                              null,
                              label,
                              "Select Service",
                              JOptionPane.PLAIN_MESSAGE,null,
                              possibilities,
                              "AddressCleanse");
//          If a string was returned, say so.
          if ((serviceModel != null) && (serviceModel.length() > 0)) {
              System.out.println("You've selected " + serviceModel + "!");
              setVariables();
              return true;
          }else{
//               If you're here, the return value was null/empty.
               System.out.println("Null or Bad service selected!\n Exiting program.");
               return false;
          }I would like to instead return the response as an integr so I can then use a switch, rather than recursive if, else if logic.
Apparently java doesnt allow switches to use strings (like PHP does)
any ideas?

Just a question more than an answer: would using a hashmap ever work here? where the key is a string and the value is an (???) object that implements an interface that would allow you to call an appropriate method? Perhaps one could use the keySet() and toArray to build the Object array for the JOptionPane. I thought I read something about this somewhere, but am not sure....

HELP --JOPtionPane.showInputDialog

I was developing a employee information system in swing.
On the way of development,the major problem the is occuring
is that two JOPtionPane.showInput Dialog boxes are appearing
at a time.When I fetching the data to the JOPtionPane.showInput Dialog box and then clicking the "ok" option button,another JOPtionPane.showInput Dialog box appears making the program difficult to
bug.
Please suggest ways to solve this bug.

It is more likely that your program has logical errors, just search for all JOptionPane.showInputDialog(...) statements and insert a println statement before it to trace the source of the problem.

JOptionPane.showInputDialog and the cancel button

so i'm using a JOptionPane.showInputDialog, and everything works except when i click the cancel button to exit the window, it gives me an error.
how can i remedy this?
here's a section of my code: (a is an array, as is b)
firstWord = JOptionPane.showInputDialog
("What company's sloagan is/was: "+a[count]+"?");
if(firstWord.equalsIgnoreCase(b[count]))
JOptionPane.showMessageDialog (null,
"Thats Right, the company was "+b[count]+".");
count++;
int YesNo = JOptionPane.showConfirmDialog (null,
"Do you want to play again?", "Choose One", JOptionPane.YES_NO_OPTION,JOptionPane.INFORMATION_MESSAGE);
if(YesNo==1) //this should exit out if you click no
System.exit (0);
if(count==10)
JOptionPane.showMessageDialog(null,
"Game Over. You Won.");
System.exit (0);
else
JOptionPane.showMessageDialog (null,
"Sorry, you aren't that smart. Guess again.");
}]

1- Seems like you misstyped your code tags...
2- When you say: "it gives me an error", please provide details (e.g. stack trace)
3- Read the API doc, it says: showInputDialog returns user's input, or null meaning the user canceled the input.
So firstWord.equalsIgnoreCase(b[count]) will throw a NullPointerException in that case.
You might check for null value.
Note:str1.equals(str2) will throw a NullPointerException when str1 is null, but str2 can be null without a NullPointerException being thrown:String str1 = null;
String str2 = "toto";
System.out.println(str1.equals(str2)); // NullPointerException
System.out.println(str2.equals(str1)); // ok (prints false)

How to put JPasswordField on JOptionPane.showInputDialog ?

Hi,
I want to use "JOptionPane.showInputDialog" and a "JPasswordField" on it.
How can I put "JPasswordField" on JOptionPane.showInputDialog?
Here is my code but there is a simple JTextField automatically generated on showInputDialog.
// JPasswordField pf = new JPasswordField();
// String str = new String (pf.getPassword());
String pass = JOptionPane.showInputDialog(null,
                               "Enter password to access:",
                               "Demanding Password",
                               JOptionPane.QUESTION_MESSAGE);I thank you in advance.

How to customize JOptionPane.showInputDialog?

Is there a way to change the text on the ok- and cancel buttons in the JOptionPane.showInputDialog()?
I'm trying to make the input dialog display Norwegian text in the OK and Cancel buttons, but it seems impossible...?
None of the JOptionPane.showInputDialog methods take the options-array as input, and none of the JOptionPane constructors let me create a input dialog.
Does anyone know how this can be done, or do I have to write my own InputDialog?

You can get a partial list of the properties from the UIDefaults Hashtable returned by UIManager.getDefaults(), but for the rest you have to look at the source code. For example, I got this from the source code of BasicOptionPaneUI.          } else if (type == JOptionPane.OK_CANCEL_OPTION) {
                    defaultOptions = new ButtonFactory[2];
                    defaultOptions[0] = new ButtonFactory(
                        UIManager.getString("OptionPane.okButtonText",l),
                        getMnemonic("OptionPane.okButtonMnemonic", l),
                        (Icon)DefaultLookup.get(optionPane, this,
                                          "OptionPane.okIcon"), minimumWidth);
                    defaultOptions[1] = new ButtonFactory(
                        UIManager.getString("OptionPane.cancelButtonText",l),
                        getMnemonic("OptionPane.cancelButtonMnemonic", l),
                        (Icon)DefaultLookup.get(optionPane, this,
