Problem with JSplitPane

Hi!
I have the following problem with JSplitPane: Whenever I add two components to the splitpane and then add the splitpane to a JPanel, the left component is minimized, i.e. not visible. I always have to manually readjust the splitter in order to see the left component. I also tried a bunch of combinations of setSize, etc. but nothing seems to help.
Here's some code:
public void setTables(Vector<DBTable> vec)
          _panel.setSize(650, 500);
          DefaultListModel m = new DefaultListModel();
          _tableList = new JList(m);
          // _tableList.setSize(new Dimension(300, 400));
          _infoArea = new JTextArea();
          _infoArea.setEditable(false);
          // _infoArea.setSize(new Dimension(250, 300));
          MetaDataListener listener = new MetaDataListener(_infoArea, _tableList);
          _tableList.addListSelectionListener(listener);
          for (DBTable table : vec)
               m.addElement(table);
          JScrollPane scroll1 = new JScrollPane(_tableList);
          JScrollPane scroll2 = new JScrollPane(_infoArea);
          JSplitPane split = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, true, scroll1, scroll2);
          split.setSize(new Dimension(600, 480));
          _panel.add(split, BorderLayout.CENTER);
          scroll1.setPreferredSize(new Dimension(300, 400));
          scroll1.setSize(new Dimension(300, 400));
          scroll2.setPreferredSize(new Dimension(300, 400));
          scroll2.setSize(new Dimension(300, 400));
          _panel.setVisible(true);
                                     //_frame referes to a JInternalFrame and _panel surprisingly to a JPanel
          _frame.getContentPane().add(_panel, BorderLayout.CENTER);
          _frame.setVisible(true);
          split.setDividerLocation(50.0);
     }Thanks!

Nevermind I fixed it!

  • Big problem with JSplitPane

    Hello,
    I feel I'm going mad with Swing.
    I have a main main JTabbedPane: main.
    First component: JEditorPane : source
    Second Component: JPanel : view( = new JPanel())
    In view I have:
    JPanel toolbox to NORTH and JSplitPane: ds to CENTER.
    In ds I have:
    Left component: new JScrollPane(design) where design=new JPanel()
    Right component: JSplitPane(....) : called pe
    First problem:
    In ds the left component is too small. I tried to use all functions available , no result. I want the right component(pe) to have width=200, but no chance. It is too big. Why?
    Second problem:
    The scrolls are not appearing on the left at the ds(JSplitPane)
    Third problem:
    I add different components to design JPanel(the one which is placed into a JScrollPane which is related to the second problem) but nothing happens. They won't appear on design which is the same and without no scrolls.
    Please help me solve this Swing mistery.
    Thank you all.

    The split pane, by default, will size its two halves based on their preferred sizes. If the combined preferred sizes are too small (for the size of the spilt pane) then the extra space is distributed based on JSplitPane's resize weight. The default is to add the extra to the right hand side, see JSplitPane.setResizeWeight for an explanation. If you really want the right hand side to be exactly 200 pixels then you can programmatically move the divider to a location that would leave the right hand side to be 200. Or you can set the preferred size of the component you place there to 200 and set a resize weight that will give the extra space to the left instead of the right.
    I am not sure about why the scroll bars are not showing up. Does it need scroll bars?
    May I suggest creating a simple demo app to show the problem? Often I solve my own problems doing this otherwise you have some code for us to look at and play with.

  • Problem with JSplitPane.setDividerPosition

    An applet has a split panel, a list of items shown to the left and a map display to the right.
    The problem I'm getting is that the divider bar insists on starting life in the middle.
    My intialisation looks like this:
        protected void initGui() {
            Container content = getContentPane();
            JMenuBar bar = new JMenuBar();
            setupMenu(bar, MK_MENU_DATASTORE, dataStoreMenu);
            setJMenuBar(bar);
            content.setBackground(new Color(0xfffeff));
            layerList = new JPanel();
            layerList.setLayout(new BoxLayout(layerList, BoxLayout.Y_AXIS));
            layerList.add(Box.createVerticalGlue());
            mapPanel = new ViewPanel();
            JSplitPane split = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, layerList, mapPanel);
            split.setDividerLocation(ViewLayer.LAYERBOX_WIDTH);
            split.validate();
            content.add(split);
            validate();
        }Now the divider location I set seems to get squirreled away somewhere, because when I click the bar with the mouse it jumps to the correct position but it refused to initialise to the right position.

    Oops! Spotted it.

  • JTextArea as ListCellRenderer in JPanel with JSplitPane and text wrapping

    Hi.
    I have problem with JTextArea text wrapping. The JTextArea is used as ListCellRenderer in JList and it has set:
    textArea.setLineWrap(true);
    textArea.setWrapStyleWord(true);I can dynamically add new Notes, modify and remove notes on JList. The capacity of the Text is various so the size of cells is various.
    The JList is in JScrollPane configured like this:
    JList notesList = new JList();
    JScrollPane scrollPane = new JScrollPane(
                        JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
                        JScrollPane.HORIZONTAL_SCROLLBAR_NEVER
    scrollPane.setViewportView(notesList);This scrollPane is put on the left component in the JSplitPane.
    When I put one note with any capacity I want, word wrapping works great even if I move the splitter. The size of cells in JList changes as I want. When JList has more width the cells have less height, when JList has less width the cells height grows because of text wrapping.
    Problem
    Sometimes and I don't know when and why the cells size is fixed.
    I put new note to the list, JList lays the cell, calculate the size and disply it. It is good but when I move splitter the size of the cell is the same. It seems that during moving the splitter the JTextArea doesn't calculate their size.
    I would like in every cell in JList to see whole text wrapped. When I make more width by slider I would like to see whole text with less number of rows. When I make less width with the slider I want to see whole text wrapped and more higher cells.
    Can someone help me where to looking for ideas.

    This is a common problem.
    There is no renderer associated with your getColumnClass() return value.
    You see, even if you set the renderer some common operations (undocumented) reset the renderer to null.
    in getColumnClass() you must get the renderer for a particular class and if it is null, set it, then return.

  • KeyCode problem in JSplitPane

    Hi,
    I have a little problem with my swing application. My aplication is like this:
    A JFrame witch contains a JPanel witch contains a JSplitPane witch contains one left and one right element witch are both a JPanel with a JList with more elements in it. I used ActionMap and InputMap classes of the split to implement a TAB key action. The action was to give focus to one list at a time when the TAB key was pressed. That's fine so far, but when i tried to implement an action for the F76 key i got into problems. I used the same ActionMap-InputMap pair, but the listener isn't called, but instead it does exactly what the TAB key does:switching focus. I've noticed that there was exactly this action defined for that input map for F6. So i deleted it , but this strange thing still ocuurs. How can i force my application to do what i want on F6 and not what it wants? I don't know if this helps but: i'm using a RedHat 7.2 system (with the latest upgrades), and i didn't tested my application on other system, or other jdk than the one i'm curently using:1.3.1_01 .
    Please help.
    Thanks.

    I used the following code
    private void initMater() {
    try {
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    catch(Exception e) {}
    // after the look and feel is installed we override .....
    Object obj = new UIDefaults.LazyInputMap(new Object[] {
              "UP", "negativeIncrement",
              "DOWN", "positiveIncrement",
              "LEFT", "negativeIncrement",
              "RIGHT", "positiveIncrement",
              "KP_UP", "negativeIncrement",
              "KP_DOWN", "positiveIncrement",
              "KP_LEFT", "negativeIncrement",
              "KP_RIGHT", "positiveIncrement",

              "END", "selectMax"
              // "F8", "startResize", NO !
              // "F6", "toggleFocus" NO !
    UIManager.put("SplitPane.ancestorInputMap",obj);

  • 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,
    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

  • Problem with threads and/or memory

    I'm developing an application where there are 3 threads. One of them sends a request to the other, and if the 2nd can't answer it, it sends it to the 3rd (similar to CPU -> CACHE -> MEMORY). When i run the program with 1000-10.000 requests, no problem occurs. When i run it with 300.000-1.000.000 requests, it sometimes hangs. Is this a problem with the garbage collector, or should it be related to the threads mecanism.
    (note: eache thread is in execution using a finite state machine)

    i had been running the program inside Netbeans.
    Running the jar using the command line outside
    Netbeans i have no more problems... Does Netbeans use
    it's own JVM?Depends how you set it up, but look under the options. There are settings for the compiler and jvm that it uses.

  • Installation problem with NW'04 SR1: database connection failed

    Hi all,
    while installing NW '04 SR1 on Windows Server 2003 SP1 and MS SQL Server 2000 SP4 I ran into an error related to the database connection. While performing the step "Load Java Database content" SAPinst crashes with the message
    com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
    The connection to the SLQ Server with e.g. the Query Analyzer is OK. I had a problem with this installation setup before (have a look at the corresponding <a href="https://forums.sdn.sap.com/thread.jspa?threadID=338638&tstart=0">thread</a> ), the JDBC drivers where missing on the installation master but after copying them in the right direction the installation went on with no problem up to this point...
    Has anybody an idea what could have happened here? Is this maybe a problem connected to the one I recently had
    Below I attached the sapinst.log and jload.log with more detailed messages.
