Problem with JFormattedTextField

Hi,
I Want to set Max length of text in JFormattedTextField..
I've tried to extend PlainDocument and override insertString and updateString, but it doesn't work.
How can do it.
Thanks.

I've solved the problem with a subclass of DocumentFilter.
Overriding the following methods : insertString,remove and update

    }The problem is that the first time I pass through a textfield, it selects its content. But once, it has been selected, it can't be selected anymore...
    And if I make a setValue() during the initialization, it cannot be selected at all!
    Does anyone know how to fix this?
    Thanks!

    Should work now...

  • More problem with JFormattedTextField

    Here is the code where I want size and input validation for JFormattedTextField
    MaskFormatter f10=new MaskFormatter("***************");
    f10.setValidCharacters("0123456789");
    t4= new JFormattedTextField(f10);
    It's behaving in funny way. It allows me only specfied no of characters(15 here) and only nos. But after entering nos and when it changes the focus, the entered data is disappearing. What could be the problem?

    Interesting Problem,
    Watching for result.

  • Big problem with JFormattedTextField.

    When I use a JFormattedTextField to receive on input just letters when the JFormattedTextField loses focus it just clear the field! Why that?
    try  {
             MaskFormatter mask = new MaskFormatter("????????????????????");
             mask.setValidCharacters("abcdefghijklmnopqrstuvxwyzABCDEFGHIJKLMNOPQRSTUVXWYZ");
             nameText = new JFormattedTextField(mask);
       catch(ParseException pe) {
       }When the JTextFormattedTextField loses the focus it gets empty. Why?
    And I have another important question: Besides letters, I need to receive empty spaces on my JFormattetTextField. How can I set this on setValidCharacters method?
    Thanks!

    You should be displaying a message when you handle an Exception.
    If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
    Don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.

  • Problems with MaskFormatter and JFormattedTextfield

    Hi,
    I'm new to the forum and Java programming so if anyone is willing to answer this query with a small degree of patience I would be immensely, humbly grateful!
    I'll say firstly that I wrote the program in jdk1.4.2 then recompiled it in 1.6.0 in the vain hope that the problem would go a way, but no such luck.
    Right, I'm using one Formatted textfield with a MaskFormatter on which I change the mask according to what information I want from the user:
    class myFormatter extends MaskFormatter {
              String key;
              public void setMask(String k){
                   key = k;     
                   if (key.equals("text")) {
                        try{
                             super.setMask("*************"); // for text, eg star names
                             super.setValidCharacters("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\u0020");
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
                   else if (key.equals("num")) {
                        try{
                        super.setMask("****#"); // for numbers 1-10000 eg frame num
                                    super.setValidCharacters("0123456789\u0020");
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
                   else if (key.equals("epoch")) try{
                        super.setMask("####.#"); // for epoch
                        super.setValueContainsLiteralCharacters(true);
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
                   else if (key.equals("yna")) try{
                        super.setMask("L"); // for single lower case characters eg y/n/a
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
                   else if (key.equals("coord")) try{
                        super.setMask("*## ## ##"); // for RA/Dec
                        super.setValueContainsLiteralCharacters(true);
                        super.setValidCharacters("0123456789+-\u0020");
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
                   else if (key.equals("reset")) try{
                        super.setMask("*********************"); // accept anything
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
                   else  try{
                        super.setMask("********************"); // accept anything
                        }catch (java.text.ParseException e) {
                        System.err.println("Problem with formatting: " + e.getMessage());
                        System.exit(-1);
    -----------------------------------------------------------------------------------------------------Ok, now I've only gotten as far as checking the implementation of the "epoch", "text", "yna" and "coord" keys. I've discovered two main problems:
    1. The A, ? and H masks in MaskFormatter just simply did not work; the textfield would not let me enter anything, even when setting the valid the characters, hence having to use * for implementing the "text" key.     
    But most importantly:
    2. The "coord" mask will not let me enter anything (example coordinates -32 44 55) and when I try (in particular press the backspace to start entering at the beginning of the ttextfield instead of the middle, where the cursor is put) I presented with this horrendous complaint from the compiler:

    A NullPointerException??? I even tried priming the textfield by setting the value using formatTxt.setValue(format.stringToValue("+00 00 00")).
    Does anyone have any ideas on this error (or how I can get around this without delving to much into other filtering classes)? Has anyone had similar problems with the MaskFormatter masks not accepting what they claim they do (I looked through the posts on the subject).
    Thanking you in advance for you patience........

    Hi,
    Thank you very much for your prompt reply.
    I've done as you said - written a smaller program to test each mask. They don't work quite as I expected but you're right, each mask works fine, its changing the masks that's the problem. I wrote this to test it out:
    public class testMask {

    }When I click on the "change" button, the textfield won't let me enter anything in, no matter what I change the mask from or to.
    Does anyone have any idea how I can implement the mask change dynamically? The only thing I could think of was to somehow re-initalise the textfield then do a repaint, but I don't know how or if that would even work.
    Thanking you again in anticipation,

  • Problem with PropertyChangeListener and JTextField

    I'm having a problem with PropertyChangeListener and JTextField.
    I can not seem to get the propertychange event to fire.
    Anyone have any idea why the code below doesn't work?

    If you want to listen to changes in the textfield's contents you should use a DocumentListener and not a PropertyChangeListener:

    And please use [co[/i]de]  tags when you are posting code (press the code button above the message window).

  • GUI - Problem with GridBag

    Hi everyone,
    I have been trying to get this GUI built from the ground up and I have encountered a problem with the GridBag(exception error that the fields being added can not be done. Also, my method main seems to be off track, I have a working program which the display fields have been modified to display object and everything else is the same except that I can not get the GUI to run.
    The following is the code and any suggestions as to what I can do to get this going will be appreciated. Thank you.

    Hi Bryan,
    I took your advice and decided to take a different approach to the problem I am having, I decided to stay somewhat with the basics with little knowledge I have about coding. I am new to this and I am trying to learn through the fire but it's getting hot so if you don't mind, can you tell me what I need to do to fix the error messages I am getting.
    1. "else" without "if',
    2. can't load my icon-a JPG
    3. exception in thread amin
    process complete.
    4.Text area for displaying an iteration of the input
    the code is not as long as the other one! any help will be appreciated. Also I am attaching the code to the GUI that does work but I can not seem to get the actionListener aspect to work. Thanks again.
      //this one works and it serves as a model for what I am //trying to do in the fields. as well as designate a text area                                                              //where a each entry per iteration of input is displayed

  • PostCode - problem with validation

    Hello,
    I have problem with codes in Netbeans.I Have two code.
    The first is to mask formatter and i put in on Post int code
    try
    MaskFormatter PostCode = new MaskFormatter("##-###");
    PostCode.setValidCharacters("0123456789");
    RegisterPostCode = new JFormattedTextField(PostCode);
    catch (ParseException e) {
    }The Second check, the RegisterPostCode is not null
    class Steps implements ActionListener{
       int step = 0;  
          public void actionPerformed(ActionEvent e) {
          if (step == 0){
    String NotEmptyPostCode = RegisterPostCode.getText();
             if(NotEmptyPostCode == null || NotEmptyPostCode.length() == 0) {
       jLabel4.setText("This Field is empty");
             return;
    step++;
          }Problem is the second code doesnt work and I dont now how to create code to check the JFormatterField is compatible with the first code
    Please help.

    Hi! I have an HTML region and on my "before header process" I fetch only one record (the data is got from a package I've created on the DB).
    This region has a few items and when I press the save button (I created on the screen) the value of all the items are cleared if the validation ocurrs, I don't know why, is this because the page doesn;t perfom again my "before header process"?
    Thanks!

  • JSpinner problems with alignment of text

    I experience problems with the alignment of the text within the spinner. I read a few topics on this forum. Many answers point to the solution of grabbing the JFormattedTextField from the spinner and call the setHorizontalAlignment(int) method. Seems hat doesn't work for me.
    Here is the code I wrote:
    SpinnerDateModel dateModel = new SpinnerDateModel();
    JSpinner dateSpinner = new JSpinner(dateModel);
    JSpinner.DateEditor dateEditor = (JSpinner.DateEditor)dateSpinner.getEditor();
    JFormattedTextField tf = dateEditor.getTextField();
    tf.setHorizontalAlignment(JFormattedTextField.RIGHT);
    maybe I am missing something. Please help!
    Thank You in advance.

    I'm not sure if this is the solution, but the getTextField() Method should be called on a JSpinner, rather than a SpinnerDateModel. I took this Method from the Swing Tutorial and made it static, so i could use it anywhere:
    public static JFormattedTextField getTextField(JSpinner spinner) {
              JComponent editor = spinner.getEditor();
              if (editor instanceof JSpinner.DefaultEditor) {
                   return ((JSpinner.DefaultEditor)editor).getTextField();
              } else {
                   System.err.println("Unexpected editor type: "
                                          + spinner.getEditor().getClass()
                                          + " isn't a descendant of DefaultEditor");
                   return null;
         }Besides, setting an Editor for this JSpinner is not neccesary, because it is chosen automaticaly. You only need to do so if you have implemented a custom SpinnerModel.
    Hope this was any help...

  • A problem with threads

    I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
    Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
    My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
    Thank you in advance,
    Lefty

    This was one solution from the socket programming forum, have you tried this??
    public Thread MyThread extends Thread{
         boolean active = true;          
         public void run(){
              ss.setSoTimeout(90);               
              while (active){                   
                   try{                       
                        serverSocket = ss.accept();
                   catch (SocketTimeoutException ste){
                   // do nothing                   
         // interrupt thread           
         public void deactivate(){               
              active = false;
              // you gotta sleep for a time longer than the               
              // accept() timeout to make sure that timeout is finished.               
              try{
                   sleep(91);               
              }catch (InterruptedException ie){            
              interrupt();
    }

  • Problem with Threads and a static variable

    I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
    Code functionality:
    A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
    The problem as far I understand is:
    Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
    Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
    Thanks,
    B.D.
    Code:
    private static volatile boolean bChanged = false;
    private static Thread objMainProcess;
       protected static void Init(){
            objMainProcess = new Thread() {
                public void run() {
                    while( objMainProcess == Thread.currentThread() ) {
                       GetState();
            objMainProcess.setDaemon( true );
            objMainProcess.start();
        public static void initStatusTimer(){
            if(objTimer == null)
                 objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                    public void actionPerformed( java.awt.event.ActionEvent evt){
                              SetState();
        private static void SetState(){
            if( objMainProcess == null ) return;
            synchronized( objMainProcess ) {
                bChanged = true;
                try{
                    objMainProcess.notify();
                }catch( IllegalMonitorStateException e ) {}
        private static boolean GetState() {
            if( objMainProcess == null ) return false;
            synchronized( objMainProcess ) {
                if( bChanged) {
                    SendMessage();
                    bChanged = false;
                    return true;
                try {
                    objMainProcess.wait();
                }catch( InterruptedException e ) {}
                return false;
        }

    Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
    Again as you said, There is a reason I can't call sendMessage() inside setState().
    The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
    Thanks,
    B.D.

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
    troy.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.

  • Problem with threads and camera.

    Hi everybody!
    I've a problem with taking snapshot.
    I would like to display a loading screen after it take snapshot ( sometimes i
    have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
    I was trying to use threads but i didn't succeed.
    I made this code:
    display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while((!performing.isShown()) && (backgroundCamera.isShown())){
                        Thread.yield();
                    notifyAll();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        this.wait();                   
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();This code is sometimes showing performing screen but sometimes no.
    I don't know why. In my opinion performing.isShown() method isn't working correctly.
    Does anyone have some idea how to use threads here?

    Hi,
    I've finally managed to work this fine.
    The code:
           Object o = new Object();
           display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while(!performing.isShown()){
                        Thread.yield();
                   synchronized(o) {
                      o.notify();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        synchronized(o) {
                           o.wait(1);
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();

  • Problem with threads hanging

    We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
    We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
    A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).

    String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
    We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

    Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

    Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there.  Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this. 
    We're using the following memory options:
    -ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
    -verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
    Thanks!

  • Problem with threads and ProgressMonitor

    Dear Friends:
    I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
    But I need deactivate the main class(the main class is the user interface) until the thread ends.
    I use something like this:
    LongTask myTask=new LongTask();
    myTask.start();
    myTask.join();
    Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
    What's wrong?

    Is the dialog a modal dialog? This can block other UI updates.
    In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating
