Execute code after show() in a Modal JDialog

Is there any way of executing a piece of code after a Modal JDialog's show() method ? I tried to run the code using SwingUtilities.invokeLater to no use. Any ideas ?
Thanks !

Thanks Jamie !
Adding a new thread wasn't required. I found the solution in some forum. The main issue was to get focus to a textfield in JDialog along with displaying a JPopupMenu against it. I could get the focus in but the popup wasn't showing. In brief this is what solved it.
Assuming JTextField is testField. I add this listener to the textField just before calling JDialog.show().
<code>
     private FocusListener fListen = new FocusListener()
          public void focusGained(FocusEvent e)
               // showPop() logic
          public void focusLost(FocusEvent e)
               testField.removeFocusListener(fListen);
               testField.requestFocus();
</code>

Adf valueChangeListener autosubmit=true, execute code after update model

Hello.
I'm working with the valueChangeListener and autosubmit="true". I'll try to explain my situation
with an example.
jsp:
<af:form>
     <af:panelForm>
          <af:inputText
               id="value1"
               label="Value1"
               value="#{index.myObject.value1}"
               autoSubmit="true"
               valueChangeListener="#{index.changeListener1}"/>
          <af:inputText
               id="value2"
               label="Value2"
               value="#{index.myObject.value2}"/>
     </af:panelForm>
</af:form>
backing:
public class Index {
    private MyObject myObject;
    public Index() {
        myObject = new MyObject();
    public void changeListener1(ValueChangeEvent valueChangeEvent){
          doSomethingWithMyObject(myObject);
    // ... get/set of myObject
MyObject:
public class MyObject {
    private String value1;
    private String value2;
    public MyObject() {}
     //getters/setters...
}In the line doSomethingWithMyObject(myObject) i need myObject with the actual values in the user form.
in the example above, the first time the page is rendered and shows the inputs
if the user captures something in the 1st input and then hits the tab to go to the other input
the valueChangeEvent is fired, and the code in "index.changeListener1" executed, but at this moment
the model (myObject) hasn't been updated with the data that the user entered (Validation Phase).
So i need a way to execute my code called from the "valueChangeEvent" but after the model has been updated
Some notes about my problem:
     - The doSomethingWithMyObject(myObject) could update data in myObject
     - About binding="#{x.y}":
     I know i can use the binding attribute in the tag <af:inputText binding="#{x.y}"> and then in the code of
     the changelistener the binded component always have the most recent value from the user,
     but i cant' use that, the method needs a MyObject instance.
     - I don't think create a new instance of MyObject and populate it every time the event fires is a good way
     - doSomethingWithMyObject" is a black box, so i don't know what is going to do with myObject
     - In my problem there are more than 2 inputs there will be N components M listeners.
What I'm trying:
     PhaseListener:
     I have been implementing a solution with a PhaseListener like
     public void afterPhase(PhaseEvent phaseEvent) {
          // just after UPDATE_MODEL_VALUES phase
          FacesContext f = FacesContext.getCurrentInstance();
        Index i = (Index) f.getApplication().createValueBinding("#{index}").getValue(f);
          // at this point the model is updated
          doSomethingWithMyObject(i.getMyObject);
     public PhaseId getPhaseId() {
        return PhaseId.UPDATE_MODEL_VALUES;
          this works but i don't know if this is the answer according to this post (unanswered at this time):
          http://forums.oracle.com/forums/thread.jspa?threadID=611643
     says something about that PhaseListener is not thread safe and blocks the application with more
     than 1 user.
     A wrapper:
     using the controls binded to the backing
     public class Index {
          private MyObject myObject;
          private CoreInputText inputValue1;
          private CoreInputText inputValue2;
          //listener
          //getters/setters
     }     make a wraper like
     public class MyObjectW {
         private Index index; // wrap the backing index
         public MyObjectW(Index index) {
             this.index = index;
         public String getValue1(){
             return (String) index.getInputValue1().getValue();
         public String getValue2(){
             return (String) index.getInputValue2().getValue();
         public void setValue1(Object v){
             index.getInputValue1().setValue(v);
         public void setValue2(Object v){
             index.getInputValue2().setValue(v);
    }and then call in the index backing:
doSomethingWithMyObject( new MyObjectW(this)); so it will access to the most actual values from user at the valueChangeEvent
But i really would like some way to execute my code called from the "valueChangeEvent" but after the model has been updated
so i dont need to wrap or implement PhaseListener
what do you think, what do you suggest, have any solution or a way to do what I'm trying?
thank you for your help...

Hello Frank, thanks for the response.
When you say
"If you need an updated object in this listener then you can update it from the value change listener as well"
you mean i can update the object by myself with the value from getNewValue()? or is there another way
to call to update the models at this time ?
I know i have the methods "getOldValue()" and "getNewValue()" in the "ValueChangeEvent" but what if i need
the actual value from the user in other control than the one that fires the event
example
Two inputs:
in the input1 the user enters some data
in the input2 when some data is entered it fires valueChangeListener (autosubmit=true)
in that case what if i need the value the user just entered in the input1 in the valueChangeListener of
the input2.
In general the app I'm working must do:
dynamically generate the controls in the form (inputs, selects etc)
Attach the control values to a model ( <af:inputText value=#{model.x}"/>
sometimes execute some script when a value change in a control (valueChangeListener)
those scripts uses the model (and needs to be an updated model)
          script = " if (value2 = 'xyz') then value1='abc'; return true;";
if the model is not updated
the script will use old values and will be wrong
or if the script change some value in the model, when the update model phase occurs the value from
the script is lost.
that's why i need to work directly with the model and not the values in the ValueChangeEvent
Is there a way to use something like an action in the change of a control value?
that way the code will execute in the invoke application phase, can this be done ?
how i can execute code in the invoke application when a valueChangeEvent occurs ?
hope this help to explain more my situation.
Thank you for your help and time.

How to execute code after JSF startup?

Hello,
I need to execute some initialization code after JSF startup, so I cannot do the usual ServletContextListener trick, as that runs before JSF is completely initialized. Any ideas?
Kind regards,
Ulrich

I can think of one way to do this (which might be a bit cumbersome for what you are trying to do) : use the Spring framework's web integration classes.
You can specifiy a context listener in your web.xml :
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
That way, Spring will load an ApplicationContext, and in that context you can specify a Spring bean that will be instantiated at application startup, which will perform whatever logic you need to do.
More info here :
http://static.springframework.org/spring/docs/2.0.x/reference/webintegration.html

When i execute code, it shows "Record 1/?" and takes too much of time to execute.

Hi all,
I have s form with push_button (SEND TO BACKUP).
For this push button - SEND TO BACKUP, i have coded the below for Trigger - WHEN BUTTON PRESSED.
DECLARE
CNT NUMBER;

   SELECT COUNT(CHND_DATE) INTO CNT FROM RMC_INACTIVE_MAT_RATES_MP_PREV WHERE CHND_DATE=I.CHND_DATE;
IF CNT > 1 or cnt=1 THEN
   MESSAGE('INACTIVE MATERIAL RATES FOR MEGAPACK ALREADY EXIST IN BACKUP WITH THIS DATE ');

END LOOP;
COMMIT ;

END;
It is working but with lot of delay, it takes too much of time.
After i run this form & as i press the button, it shows "Record 1/?" in the below and it takes almost 5 mins to execute completely and dhow the message.
Can you tell why is it showing "Record 1/?" below ???
How to reduce the delay??
Thank You.

Executing code after a transition has finished

Hi,
Is there any kind of language construct in JavaFX to allow a certain block of code to be executed after a transition has finished? Or do I have to pause the current thread with sleep() or similar?
The ideal would be something like this, but of course such a thing like onComplete does not exist AFAIK:
FadeTransition {node: selectedNode duration: 1s fromValue: 1 toValue: 0 onComplete: executeThis()}.play();

Hello,
By "delete node" you mean delete it from scene? This example works for me:
var stage: Stage = Stage {
    width: 250
    height: 250
    scene: Scene {
        content: [
            text = Text {
                layoutY: 30
                opacity: 0.0
                content: "Example transition"
            Button {
                layoutY: 70
                text: "Click me"
                action: function() {
                   FadeTransition {
                        node: text
                        fromValue: 0.0
                        toValue: 1.0
                        duration: 200ms
                        action: function() {
                            delete text from stage.scene.content;
                    }.play();
}Saa

Acrobat looses windows focus after showing a wxWidgets modal dialog

Here's a code sample:
     AVWindow dlgWindow = AVWindowNewFromPlatformThing(AVWLmodal, NULL, NULL, gExtensionID, dlg->GetHWND());
    AVAppBeginModal(dlgWindow);
    dlg->ShowModal();                                   // dlg is a wxDialog*
    AVWindowDestroy(dlgWindow);
    AVAppEndModal();
This works in so far as the wxWidgets window is modal with respect to Acrobat, however when we do AVAppEndModal Acrobat does not get the windows focus back. In fact some other open application gets it instead, which is a problem for the end user.
If I take away the Begin and End, I do not get the focus problem, however I do not get the modal nature either.
Any ideas on how to solve this?
Thanks
Simon

Hi,
I see this too.
The only workaround I found is to use Windows api to find the Acrobat window and switch back to it maually. There is a flicker, but at least the user is back in his original window.
I can confirm this behaviour on Wndows XP, Vista, and 7 in Acrobat 8, Acrobat 9 and Acrobat 10.
Simple code that works for me:
void SetWinFocusBackToAA()
    #ifdef WIN_PLATFORM
        if (gHWND) SetForegroundWindow(gHWND); //AA 8 MDI
        else
            HWND AAhwnd = FindWindow(L"AcrobatSDIWindow", NULL);
            if (AAhwnd) SetForegroundWindow(AAhwnd);
    #endif
I do not see such a problem on Mac OS X.
I suspect the problem lies in setting correct parent for the modal window, but I have not been able to find one (for some years now).
Also this does not happen when the modal wx dialog is a child of another wx windows (a modeless window).

Execute code after Spry region redrawn / added to DOM

Hi,
I'm integrating my Spry event data with a YUI calendar.
Everything is working and event dates are highlighted on the YUI calendar. There is one last thing I wish to do which is to update the YUI calendar with a Spry Tooltip. The div regions for the tooltip text are generated dynamically by via a Spry repeating region. What I am failing to do is attach the tooltips to the YUI calendar after the Spry repeating region has been added to the docuement DOM. So the Spry Tooltip function cannot find the ID of the tooltips.
I have a dataset observer "onpostload" which seems to fire when the data is loaded but before the document dom has been updated by Spry. How can I ensure I wait for Spry to update the region and hence DOM with the new data before triggering the tooltip code?
Cheers
Phil

You got different kind of observers in Spry Data.
- Dataset observers:
datasetname.addObserver( observer )
- Spry Region Observers:
Spry.Data.Region.addObserver( 'region-id', observer );
The dataset observers send out notifications when there is a event happening inside the Spry Data Sets. The one you mentioned is part of this (onPostLoad). These are great to monitor your data changes, but in your case. You don't want to use these.
The Spry region observers respond to events that are happening in side the region. For example onPreUpdate, this event is called when the region is about to generate / insert new markup in to your region. But you also got the onPostUpdate. This is the observer you are looking for, it gets called once the region has re-generated its code / html. It gets fired directly after the new HTML has been inserted.
Small note about the region observers, these require a id= attribute. This id attribute must be placed on the same element as the spry:region. To learn, and read more about the observers i would like to referrer you to this article:
Data Set and Region Overview
Its rather large, but using the browser build in find function you should be able to locate the sections about the observers
Hopes this helps,

Execute javascript after update and submit in Skillbuilders Modal Page

Hi,
I'm editing, say, list of my employees in a tabular form opened in Skillbuilders Modal Page.
I have to execute same javascript code after the changes in the tabular form have been submitted.
I've tried using a Dynamic Action fired on Page Load, but that gets executed before the update is completed.
Does anyone have an idea how to accomplish this?
Thank you!

Thank you for your answers.
Yes, I'm trying to execute javascript code on the child page, the modal one.
Basically, there's a button on my parent page which opens the modal page. The modal page has buttons Cancel, Delete and Save. Clicking Save button submits the changes and if there are errors, errors are shown and we stay on the modal page.
My modal pages are all of fixed dimensions and if there are errors, I have to adjust the other regions (adjust their height, add a scrollbar, etc) in order to show everything in the modal page.
I have written a function that does exactly that, but I have to execute the function after the page is loaded and the regions are shown. But, if I execute it using onload attribute, or setting a dynamic action which fires on page load, the function gets executed during the submit, before the regions are shown.
I hope I have managed to clear up the problem.
As always, thank you.

Execute Java code after login

Hi experts,
I'd like to execute some Java code after a successful login. I guess I could write a custom login module or use a WD Java iView to do this but a "better" solution may exist.
Regards,
Pierre

Customizing your login module is probably your best bet. As soon as you're user is authenticated, you can execute your custom Java code.
From my experience, I have not seen an easier / cleaner way to capture that event.

Problems with 'background' JFrame focus when adding a modal JDialog

Hi all,
I'm trying to add a modal JDialog to my JFrame (to be used for data entry), although I'm having issues with the JFrame 'focus'. Basically, at the moment my program launches the JFrame and JDialog (on program load) fine. But then - if I switch to another program (say, my browser) and then I try switching back to my program, it only shows the JDialog and the main JFrame is nowhere to be seen.
In many ways the functionality I'm looking for is that of Notepad: when you open the Find/Replace box (albeit it isn't modal), you can switch to another program, and then when you switch back to Notepad both the main frame and 'JDialog'-esque box is still showing.
I've been trying to get this to work for a couple of hours but can't seem to. The closest I have got is to add a WindowFocusListener to my JDialog and I hide it via setVisible(false) once windowLostFocus() is fired (then my plan was to implement a similar functionality in my JFrame class - albeit with windowGainedFocus - to show the JDialog again, i.e. once the user switches back to the program). Unfortunately this doesn't seem to work; I can't seem to get any window or window focus listeners to actually fire any methods, in fact?
I hope that kind of makes sense lol. In short I'm looking for Notepad CTRL+R esque functionality, albeit with a modal box. As for a 'short' code listing:

Hi,
Many thanks for the reply. Isn't that what I'm doing with the super() call though?
As in, in Main.java I'm doing:
setupProjectDialog = new SetupProject( frame, "Create Your Website Project", true );Then the constructor in SetupProject is:
public SetupProject( final JFrame frame, String title, boolean modal ) {
          // Setup the JDialog
          super( frame, title, modal );
          And isn't the super call (since the class extends JDialog) essentially like doing new JDialog(frame,title,modal)?
If not, that would make sense due to the null pointer exception errors I've been getting. Although I did think I'd done it right hence am confused as to the right way to handle this,if so.
Thanks,
Tristan

Freezed modal jdialog in japplet

I have made an applet program whose method javascript calls. And the method of the applet shows modal JDialog. But, after showing modal JDialog, the applet is locked.
In Windows XP + JRE 6.2 + Firefox 2.0, it is locked just after showing modal JDialog.
But in Windowx XP + JRE 5,4,3 + Firefox 2.0/IE, it is OK(working well) And, in Other OSes and Other browser, it is OK
You can test this and watch java source in the below link.

Is there a way to display a non modal JDialog on JApplet

Whenever I try to add a non modal JDialog over a JApplet, the JDialog freezes and components on it never gets painted. After a disappointing search over web, I've kinda begin to hate swing. I am shocked that a very basic thing like this is so hard to achieve in Java. Any solution folks?
My code is as follows:
import java.awt.Frame;
import javax.swing.JApplet;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JButton;
public class DialogApplet extends JApplet {
     private javax.swing.JPanel jContentPane = null;
     private JButton jButton = null;
      * This method initializes jButton
      * @return javax.swing.JButton
     private JButton getJButton() {
          if (jButton == null) {
               try {
                    jButton = new JButton();
                    jButton.setText("Click Me");
                    jButton.setBounds(75, 80, 147, 34);
                    jButton.addActionListener(new java.awt.event.ActionListener() {
                         public void actionPerformed(java.awt.event.ActionEvent e) {
                              Frame f = javax.swing.JOptionPane.getFrameForComponent(jContentPane);
                              JDialog pi = new JDialog(f, "MainFrame Dialog", false);
                            pi.getContentPane().add(new JLabel("I got to be working Bossie!!!"));
                            pi.pack();
                            pi.setLocation(75, 80);
                            pi.setVisible(true);
                            try {
                            Thread.sleep(10000);
                        } catch (InterruptedException e1) {
                            e1.printStackTrace();
                            pi.setVisible(false);
               catch (java.lang.Throwable e) {
                    e.printStackTrace();
          return jButton;
     public static void main(String[] args) {
      * This is the default constructor
     public DialogApplet() {
          super();
          init();
      * This method initializes this
      * @return void
     public void init() {
          this.setSize(300,200);
          this.setContentPane(getJContentPane());
      * This method initializes jContentPane
      * @return javax.swing.JPanel
     private javax.swing.JPanel getJContentPane() {
          if(jContentPane == null) {
               jContentPane = new javax.swing.JPanel();
               jContentPane.setLayout(null);
               jContentPane.add(getJButton(), null);
          return jContentPane;
}

try this, it is really simple, just to look at
example from the swing tutorials.
Thanks my friend, If you carefully observe my code, I also needed some piece of code to run in the background ((The thread.sleep() part)) while displaying the dialog. The problem was the JDialog used to freeze and components on it never used to get painted. Finally I managed to find a way out. If we try to display a JDialog with a new thread, The event dispatching thread takes precedence and the painting of components on the JDialog happens only after even dispatching thread is done. All I did was display JDialog in the event dispatch thread and run the background process in new thread.

Non modal JDialog

Hi All,
I want a non modal JDialog which is used to show the message to the user that it is searching for the records, when a search is performed and records are retrieved from the database. When the search is going on user might hit cancel on the JDialog to cancel the search. My problem is, the cancel button on the Search dialog is not catching the event and user is not able to select the cancel option on the dialog.
Here is my code :
class SearchWindow extends JDialog {
private JPanel btnPanel;
private JLabel lblSearch;
private JButton btnCancel;
* Constructor
public SearchWindow() {
super((Frame)null, false);
setTitle("Searching Shipment Legs");
cancelled = false;
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent evt) {
close();
Container contentPane = getContentPane();
contentPane.setLayout(null);
addButtons();
pack();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setSize(new Dimension(300, 100));
setSize(300,100);
setLocation((screenSize.width-700)/2,(screenSize.height-450)/2);
private void addButtons() {
btnPanel = new JPanel();
btnPanel.setLayout(new BorderLayout());
lblSearch = new JLabel("Searching..........");
btnCancel = new JButton("Cancel");
btnPanel.setBackground(Color.lightGray);
lblSearch.setBackground(Color.lightGray);
btnCancel.setBackground(Color.lightGray);
btnPanel.add(lblSearch, BorderLayout.CENTER);
btnPanel.add(btnCancel, BorderLayout.SOUTH);
btnCancel.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent evt) {
System.out.println("cancel");
cancelled = true;
close();
btnPanel.setBounds(0,0,200,50);
this.getContentPane().add(btnPanel);
lblSearch.setVisible(true);
btnCancel.setVisible(true);
this.getContentPane().validate();
public void close() {
this.setVisible(false);
this.dispose();
public void show() {
super.show();
paintComponents(getGraphics());
this.setModal(false);
Any help is greatly appreciated.
Thanks,
Bhaskar

Hi Haroldsmith
I am calling this search window in one of my programs where on button click it will fetch the records from the database. When this process is on, search dialog is shown up. Ths dialog is shown correctly and its getting closed as soon as the search is completed. But the probelm is its not allowing me to click on cancel button.

Stopping execution without modal Jdialog

Hi there,
I am writing a gui that needs to wait for a button click. I used to use a modal JDialog for this, which worked fine, but I have recently changed the GUI to a wizard style, and I would like to simply redraw a Card every time, rather than having a popup Dialog.
Basically the program will show info, but this info will change whenever the button is pressed.
How would I go about this without using a modal JDialog?, In other words, how can I make the program wait until button press? I am very confused about wait() and notify(), its not as simple as I thought, maybe someone can enlighten me.
Thanks for any help

Wow ok, I really screwed up on this one. Let me start again, For anyone still reading:
The program I am writing presents the User with a choice to which they must reply with using a button press. This is easily done using a JDialog that is Modal as the program waits until the JDialog is disposed.
My question is whether it is possible to achieve this effect without using a JDialog. I am doing it without a JDialog because I do not wish to have any pop ups, rather just a constantly refreshing JPanel.
To sum up: How do I achieve the modal effect of a JDialog using other Components?
I am unable to post any code right now, if anyone needs to see some I will gladly post it tommorow.
Thanks again!

Problems of executive files after PC crash

My developing PC was crushed last week when LabView project was programming. The culprit is due to device driver conflict from both Keithley USB driver and NI 488.2 driver. After recovered the corrupted project, the executive files started showing errors like"LabVIEW:Memory is full"; "LabVIEW Load error code 33: Could not load front panel data logging...";"LabVIEW:End of file encountered" ; "LabVIEW load error code 12: Could not load connector type map" etc... when executive files were distributed to run-time PC.
I removed all LabView 8.0 developing suite and re-installed LabView 8.2. However, the problem was not resolved. The executive files are ruuning no problems on developing PC but failed on run-time PC.
I brought same source files to another developping PC and made executive files. They are also running fine on run-time PC. Really, I totally have no idea what's wrong with developping PC after crushed. How comes the installer and execution files start having problems even I re-installed LabVIEW? Thanks your kinding answer.

Some of those error codes have two possible causes. They are usually given as:
Possible reason(s):
LabVIEW: Some system capacity necessary for operation is not enabled.
=========================
NI-488: File system operation error.
Since you had problems with the NI-488 driver, my guess is that the possible reason is the second listed . Uninstalling and installing LabVIEW does not automatically uninstall and re-install the hardware drivers. Try doing a repair of NI-488 or completely uninstall that and re-install.
