Waiting for a JFrame to dispose

Hello,
i have this situation: i have 2 JFrames, let's say JFrame1 and JFrame2.
JFrame1 invokes and displays JFrame2, like this:
/* JFrame1 code */
JFrame2 f2 = new JFrame2();
f2.setVisible(true);
//wait f2 to dispose
other code...My problem is how to make JFrame1 to wait until the dispose call of the other frame, and then execute the "other code"...
I tried some solutions..like a busy waiting on some flag..or using a CountDownLatch..but i didn't solve the problem...
It seems that everything i use to stop the execution of JFrame1, stops JFrame2 also, even if i run it as a new thread.
I hope someone can give me some hints!

Use a modal JDialog.

Getting a JFrame to display from a JSP, remaining JSP code waits for frame

Hello,
I'm new to Java and just started using JSPs. My objective is to call a display window (from a JSP) that shows the user a list of project selections. Once the user has made their selections and clicked a Submit button, the display class captures the selected projects to the request object as an attribute and then closes the window. The next command in the jsp then forwards the request attribute to a controller. I'm having trouble getting the display window to show-the JSP seems to hang and then timeout. Is there code I'm missing to get the JSP to stop processing while it waits for the choices to be made in the JFrame?
Below is the JSP code and the class I'm calling. I'm seeing all my debug System.out statements but no JFrame pops up. In the JFrame class, the line f.addWindowListener(... does the capture of user selections to the request attribute.
Any help will be greatly appreciated!!
JSP:
<%@ page language="java" contentType="text/html;charset=UTF-8" import="com.plumtree.remote.portlet.*,edu.app.projects.*" %>
<%
    request.setAttribute("action", "prefDisplay");
    request.setAttribute("orderby", "title");
    ServletContext jc = getServletContext();
    DualListBox dual = new DualListBox(request,(String)jc.getAttribute("db.driver"), (String)jc.getAttribute("db.connectionstring"),"title");
     JFrame f = dual.getFrame();
     f.setVisible(true);//expect code to stop here and display frame, waiting for the user to finish.
        //Debug code that tests if frame is visible at this point -came true though did not see Jframe displayed
     if(f.isShowing()){
     System.out.println("Jframe visible");}
       //Send to ProjectsController
      request.getRequestDispatcher("pc").forward(request, response);%>               ---------------------------------------------------------------------------------------------

Hmm, I was trying to avoid writing an applet. Seems my only other option then is to write a JSP that returns a javascript menu populated by options from a database call. Then I'd have the user click submit to send the options to another JSP that simply sets the request attribute and forwards to the controller. Will this be a sound alternative?

Trying to wait for a button press on a seperate JFrame- problems.

Hi,
I've been getting aquainted with Java recently. I'd like to think I was reasonable now at creating console based applications but I'm having a lot of trouble getting used to the swing API. I'm making a little game type thing at the moment and part of it involves displaying a problem to the user in a seperate JFrame and returning which option they picked. If I was doing this in a console based App I'd probably do something along the lines of:
     while (UserInput == null) { //while they haven't entered anything continue to loop.
          UserInput = InputScanner.next(); //get the user's input
     }I thought I'd do something similar for my JFrame based app but haven't been able to do it. I essentially would like the code to not execute past a certain point until one of the options on the JFrame has been picked. Here's the code for the JFrame showing the dilemma to the user:
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
* This is the window displayed to a user with dilemma details
public class DilemmaWindow extends JFrame implements ActionListener {
    int OptionPicked = 0; //the option the user picks
    JLabel DescriptionLabel;
    JButton Button1;
    JButton Button2;
    public DilemmaWindow(String WindowTitle, String LabelText, String Button1Text, String Button2Text) {
        //construct the JFrame with the relevant parameters
        setTitle(WindowTitle);
        setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
        setLayout(new FlowLayout(FlowLayout.CENTER));
        Button1 = new JButton(Button1Text);
        Button2 = new JButton(Button2Text);
        Button1.addActionListener(this);
        Button2.addActionListener(this);
        DescriptionLabel = new JLabel();
        DescriptionLabel.setText(LabelText);
        add(DescriptionLabel);
        add(Button1);
        add(Button2);
        pack();
        setVisible(true);
    public void actionPerformed(ActionEvent evt) {
        //determine which button was clicked and set OptionPicked accordingly
        if(evt.getSource() == Button1) {
            OptionPicked = 1;
        } else {
            OptionPicked = 2;
    public int GetDilemmaChoice() {
        if (OptionPicked > 0) { //if an option was picked
        this.dispose(); //clean up the window
        return OptionPicked; //return which option was picked
}The idea of this being that it constructs a window and when the GetDilemmaChoice() function is called it'll return which button has been clicked.
I do, as I said, want to wait until one of the buttons has been clicked before continuing with the execution of the code in the class that constructs the JFrame, so I made the following function:
public int GetDilemmaChoice() {
        int Choice = 0;
        DilemmaWindow MyDilemmaWindow = new DilemmaWindow(CaperDilemma.GetDilemmaName(),CaperDilemma.GetDilemmaDescription(),CaperDilemma.GetOption1Text(),CaperDilemma.GetOption2Text());
        while (Choice == 0) {
            Choice = MyDilemmaWindow.GetDilemmaChoice();
        return Choice;
    }The idea being that while the window returns that no buttons have been clicked the function loops round. The problem I'm having is that the while loop continually looping seems to hog all the CPU time or something, as the dilemma JFrame doesn't display properly (I get a blank window, with none of the buttons) and so I can't click any of the options. I've been banging my head against a brick wall all day trying to get round this and am wondering if I should put the looping in a seperate thread or something. Sadly, though, I don't know anything about threads so wouldn't know where to start.
If anyone has any idea of how to solve this problem I'd be very grateful! I hope I've managed to explain it well enough.

Why not use a modal JDialog here and not a JFrame. You probably shouldn't be coding directly to a JFrame (or JDialog) anyway but to a JPanel that can be placed on the proper root container of choice (which again here is a JDialog). You can make your JPanel as complex as desired, then place it in the JDialog, make that dialog application modal, and when you show it via setVisible(true), the application will halt at that point until the dialog has been dealt with.

Make jFrame wait for jDialog to finish

I am making a project in Netbeans i have a main Frame and some Dialog windows that open up if you press some buttons.
when one window opens i want the main Frame script to pause and wait for it to complete.
i have tried 3 different ways:
questionDialog.setVisible(true);
while (questionDialog.isVisible()) {
    try {
        Thread.sleep(200);
    } catch (Exception e) {
} but that shows the frame of the dialog box but never loads the inside and the whole application freezes.
java.awt.EventQueue.invokeLater(new Runnable() {
    public void run() {
        questionDialog.setVisible(true);
while (questionDialog.isVisible()) {
    try {
        Thread.sleep(200);
    } catch (Exception e) {
}that loaded my Dialog box but the script never waits for it to close i assume it is because it waits until "later" to show the dialog box and in that time it skips the while loop.
Thread t = new Thread(new Runnable() {
    public void run() {
        questionDialog.setVisible(true);
        while (questionDialog.isVisible()) {
            try {
                Thread.sleep(200);
            } catch (Exception e) {
t.start();
System.out.println("Dialog started");
System.out.println(questionDialog.isVisible());
try {
    t.join();
} catch (Exception e) {
}but that had the same result as the first code it waited but never showed the dialog.
where am i going wrong how should i go about this?
Scott.
EDIT:
by finish i mean become not Visible. so isVisible() will return false
Edited by: ratcateme on Nov 20, 2008 3:02 PM

You don't have to do anything to do that
questionDialog.setVisible(true), this method will block the thread, it would't keep going until the questionDialog is unvisible, this is the mistake of the way 1 and way 3.
and the way 2: the while block will be execute before the questionDialog.setVisible(true) is execute, so questionDialog.isVisible() will return false
my en is very poor, good luck!

Waiting for R/3 respose for a long time

Hi,
I am creating a loss disposal invoice,
The status of the invoice is in ' Billing document already being transferred'. It should change to ' Billing document transferred'.
In the MW cockpit, these messages are in the status 'waiting for R/3 response'
In the MW Monitor, the BDocs are in ' Intermediate state o01'
The connections seem fine between CRM and ERP.
Can anyone help please.
Pratima

Dear Pratima,
the Bdocs are in intermediate status because no response is coming from R/3 due to a short dump or update termination in your R/3 system.
You should also be able to see the errors in CRM, transaction SMW01.
Please reward points if it helps you.
Regards, José Ignacio

How to know the child JFrame is dispose

There are two JFrames, the first one is a parent, and the second is child and created by the parent.
How to parent knows the child disposed.
Because of the other member functions of parent shall be running while child is disposed.

hi!
do you know about window listener ? if not then learn it, it will solve your problem i hope.

Need to wait for answer

In the following code, my get.start(); lines, opens another jframe that is used to accept values from the user. There are 2 textfields on the jframe that the user is entering information into. However, once the get.start(); is called, the function proceeds on with itself, and doesn't wait for an answer from the jframe, which is something I understand and know, but my issue is, getting it to wait for the user to input information. I'm not sure what I can do to wait for the information before my code goes through and runs the if(goahead){.... code.
public void uploadFile(){
        //   patronObject patron = new patronObject();
        boolean goahead = true;
        getInfo get = new getInfo();
        int result = filechooser.showOpenDialog(this);
        if (result == filechooser.APPROVE_OPTION){
            String filename = filechooser.getSelectedFile().getAbsolutePath();
            System.out.println("filename = " + filename);
            if (filename.toLowerCase().endsWith(".pdf") || filename.toLowerCase().endsWith(".PDF")){
                try {
                    System.out.println("filename in uploadFILE = " + filename);
                    FileInputStream input = new FileInputStream(new File(filename));
                    ByteArrayOutputStream output = new ByteArrayOutputStream();
                    byte[] buf = new byte[1024];
                    byte[] data = null;

                    while ((numBytesRead = input.read(buf)) != -1) {
                        output.write(buf, 0, numBytesRead);
                    get.start();
                    if(goahead){
                        //   patronObject patron = new patronObject();
                        System.out.println("go to the printing section");
                        patron.setAction("updatePDF");
                        patron.setPatronID(get.getPatronID());
                        patron.setPDFName(get.getPdfName());
                        patron.setPDF(output.toByteArray());
                        sendPatron();
                }catch(FileNotFoundException ex) {
                    ex.printStackTrace();

Use a modal JDialog or JOptionPane.showInputdialog(...) instead of JFrame.

Jdev freeze while waiting for "something"

Hi All,
I have problem in my jdeveloper. everytime when i open my jsp file (contains ADF component) and it is freeze and when i look at the thread information, it is waiting for my internal db connection. If i try to comment out, it is fine but when i am going to deploy, i have to dis-comment my db connection. After that, i open another jsp file, the problem comes out again even i have comment out my db connection after deployment.
thx for reply and here is the thread information:

I was just going to suggest these two solutions myself. If you've got the time, check into this stuff.
1) use Thread.join() to wait (block) until a given
Thread completes its task.
2) Bite the bullet and learn how to use
wait()/notify() (Google should send you to some good
tutorials). Granted, it can be a complex topic, but
it is vital to know if you want to write efficient
asynchronous programs.
Good luck!

How to do custom dialog so it displays the dialog and waits for user to end

I have an application that I want to create my own dialog screens. For example, the user cliks on one frame, and I want to open a window for the user to enter data, after the user finishes, he presses OK and then the main app continues.
On the class that I open the dialog, I open it with:
NewOkCancelDialog.abrePopup();
System.out.println("Program should wait for the dialog to close");And the 'NewOkCancelDialog' class is defined like:
public class NewOkCancelDialog extends javax.swing.JDialog {
The constructor is like:
public NewOkCancelDialog(java.awt.Frame parent, boolean modal) {
super(parent, true);
initComponents();
this.setLocation(400,400);
This methods are when the user activates the button and the popup closes..
private void cierraPopupOk(){
resultados.setciudad1(this.fld_ciudad1.getText());
if (resultados.getciudad1length() < 3) {
System.out.println("Error en la entrada!");
} else {
doClose(RET_OK);
private void okButtonActionPerformed(java.awt.event.ActionEvent evt) {
cierraPopupOk();
private void doClose(int retStatus) {
returnStatus = retStatus;
this.estaAbierto = false;
setVisible(false);
dispose();
I would like to have the application in the first lines, after calling
NewOkCancelDialog.abrePopup();
to wait until the method doClose() in NewOkCancelDialog class is finnished. But right now, after the ...abrePopup() is called, it continues.
What am I doing wrong? or what am I not doing?

Use the "code" tags not the "bold" tags when posting code.
But right now, after the ...abrePopup() is called, it continues.Well your posted code doesn't show this method so we don't know what you are doing in this method.
Why are you using a static method to show the dialog? Normally the code would be:
JDialog dialog = new CustomDialog();
dialog.setVisible( true );
But you are correct with the basic idea in that you need to use a modal dialog.

nice day,
could you hepl me with some definitions, still I can't to define gap for first and last of JLabel (matrix), is there some hack for GridBagLayout,
hmmm, interesting that if I replace South JPanel and put there JPanet that contains only JButtons, then that's/just only this one (JPanel) doesn't any problems with synchronizations for repaint with JFrame,
result is: resize isn't smooth, Border jump, resize breaking,
already at a fraction of JComponents that I would like to display,
I certainly know that the reason is the LCD display, where its native resolution makes a huge problem with the edge of Border and FontSize, 'glass screen' doesn't suffering from similar diseases,
so there my question is how to stop the refresh, resize JPanels with its parents, therefore wait until the resize event ends on JFrame

Pause program code and wait for window deactivation

I have the following code. I need the frame to show then the code to pause until the frame is deactivated.
The problem is that the frame is shown but only the backgound and its contents are not shown and since the while loop waits for a deactivation it goes into an endless loop. If I press the X on the frame it still does not close. I am guessing for some reason the compiler goes into the while loop before it completes the above task of showing the frame. Can you help me out with my problem?
final viewMemRecordsFrame memframe = new viewMemRecordsFrame(ff);
memframe.show();
memframe.setLocation(80, 80);
memframe.addWindowListener(new WindowAdapter()
public void windowDeactivated(WindowEvent e)
acctnumber = -1;
memframe.dispose();
public void windowActivated(WindowEvent e)
Object waitObject = new Object();
Thread waitThread = new Thread();
waitThread.start();
while(memframe.isVisible())
try
waitThread.sleep(200);
catch(InterruptedException ie)
waitThread.stop();
ried the Thread.sleep(200) I had the same problem as above. The frame above the while loop shows but does not show the contents of the frame so an input can not be entered and the frame cannot be deactivated and it runs into an endless loop.

You appear to have some confusion about threads. Your waitThread doesn't have any code to run, which means it will terminate as soon as you start it.
"stop" is now depracated and there's really no need for it.
I'm guessing that this piece of code is activated by some kind of GUI control, which would accont for your program hanging, since no other GUI control (e.g. the close box) can be serviced until an ActionPerfomed method or similar has finished.
If you want a thread to wait for a window to close the appropriate syncrhonization methods are wait and notify, not sleep.
For example override "dispose" in "viewMemrecords with:
public void dispose() {
    synchronized(this) {   // grab the window as a monitor
          super.dispose(); // call the underlying dispose to close the window
          notifyAll();      // wake any waiting threads
   }Then the thread which is to wait does something like:
syncrhonized(memframe) {
     while(memframe.isVisible())
          memframe.wait();
      }This should make the WindowListener unecessary.
But [b[don't[/b] make code executed from an GUI action handler wait. GUI action handlers should always return promptly, creating a new Thread if any continuing action is required.

Custom JDialog, waiting for Button Press

I want to create a custom dialog so i can do the following:
Color yrColor = MyColorChooser().showDialog();
I can create the dialog just fine but i cant get it to return a value
on a button press.
Here is my code:
public class MyColorChooser extends JDialog implements ActionListener{
public MyColorChooser(){
super(Main.Frame, "Color Chooser", true);
// Gui Stuff
public Color showDialog(){
setVisible(true);
// ?? how do i have it wait for button press??
return YourColor;
public void actionPerformed(ActionEvent e) {
if( e.getSource() == Button ){
returnColor()
public void returnColor(){
Color YourColor;
JButton Button = new JButton();
}Im clueless when it comes to JDialogs.
I know i am probably approaching this all wrong.
I need guidance more in the approach rather than the code.
If anyone has any suggestions id appreciate it.
Thank you!

Maybe this simple example can give you some ideas. Note how I make the dialog modal. This will halt the program flow until the dialog is dismissed.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SimpleTextInputDialog extends JDialog implements ActionListener {
    private JTextField inputField;
    private JButton     okButton;
    private JButton     cancelButton;
    private String      value;
    private SimpleTextInputDialog() {
        setTitle("Enter a value");
        setModal(true);
        inputField = new JTextField(20);
        JPanel textPanel = new JPanel();
        textPanel.add(inputField);
        getContentPane().add(textPanel, BorderLayout.CENTER);
        okButton = new JButton("OK");
        okButton.addActionListener(this);
        cancelButton = new JButton("Cancel");
        cancelButton.addActionListener(this);
        JPanel buttonPanel = new JPanel(
                new FlowLayout(FlowLayout.CENTER, 10, 10));
        buttonPanel.add(okButton);
        buttonPanel.add(cancelButton);
        getContentPane().add(buttonPanel, BorderLayout.SOUTH);
        pack();
        setLocationRelativeTo(null);
    public void actionPerformed(ActionEvent e) {
        if( e.getSource() == okButton ) {
            value = inputField.getText();
        dispose();
    public static String getValue() {
        SimpleTextInputDialog dlg = new SimpleTextInputDialog();
        dlg.setVisible(true);
        return dlg.value;
    public static void main(String[] args) {
        String value = SimpleTextInputDialog.getValue();
        System.out.println("Entered value: " + value);
}And as always, you should study the tutorials:
"How to Make Dialogs":
http://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html

Switching Frames (cardsLayout), doing something, waiting for button

Hi,
I am switching JFrames in my application and each frame is to call a specific function and then wait for a button click.
so the code would be:
function(){
        cardsLayout.show();
        doSomeCalculations();
        waitForButtonClick
        continueWithSomething //depending on which Button was clicked
}My problem is, how to realize the waitForButtonClick?
What would you suggest? I have heard about synchronize. Is this the way to go, or is there an easier/better way?
Besides a while(notClicked) way ;-)
Thanks!

it is not that I do not want to learn Java. Please understand that Java is not with what I am earning my living, it is a tool for me, to make some task easier, which I would have otherwise have to do step by step by hand. I will never be as good as someone who spends his time with Java every day. I also have only a specific task to perform in a given time, so I need only specific information - which I am definitely willing to learn - and not all there is about Java and Swing.You must understand that at its core, your question is not about anything specific but rather it boils down to: "how to create an event driven program in Swing".
The only reasonable answer to this is to send you to the Swing tutorials where, if you have the interest, ability, and inclination, you can learn the tools needed to do Swing and event programming. If you choose not to do this, no one in this forum can help you. Period.
I hope this clarifies the situation enough, to allow someone to have a heart and point me in the right specific direction, even knowing that I might use this knowledge only once.And once again, I recommend that you hit the Sun Swing tutorials and start learning. Accept this and follow this recommendation and you will find success. If not, well,... it's your choice.
Thank you in advance for any specific help.This is as specific as it's going to get at this stage. Much luck.

Wait for a button click

Hi,
Here's the problem :
my main class calls :
LoginContext loginContext = new LoginContext("Main",
new DialogCallbackHandler());
I've made a DialogCallbackHandler class which opens a JFrame with 2 fields (TextField & PasswordField) and a button "ok".
But the LoginContext wants immediately an answer (the login & the password). How can I make the loginContext waiting for the button click.
I tried with a
while(!buttonClicked);
but it's not a good solution.
I also tried with a Thread inside this loop while and sleeps (during a 500 ms). But I think there's a better solution...
Can I make a wait, and a notify for this or not.
Thank you for your help.
Yann

Why don't you use the JOptionPane class.
I think it provides all that you need.
For example use the method :
     String pass = "azedvge";
     JPasswordField passwordField = new JPasswordField(20);
     int result = JOptionPane.showConfirmDialog(parentComponent, password, "Password check", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
     if (result == JOptionPane.OK_OPTION) {
          String p = new String(passwordField.getPassword());
          if (p.equals(pass)) {
               // OK !
          else {
               System.exit(0);
     else {
          System.exit(0);
I hope this helps,
Denis

Waiting for connection

Hy
I have created a class which make the user interface and a class which is taking care of connection to a server.
I would like that UserInterface class to waint until the ConnectServer is finished the bussines and only then to continue; but in the same time to repaint itself if necessary.
If I make the ConnectServer class a thread the UserInterface is not wainting for answer otherwise is not repinted itself.
public class UserInterface extends JFrame implements ACtionListener
JButton button;
Connection connection;
UserInterface()
button=new JButton("Connect");
button.addActionListener(this);
public void actionPerformed(ActionEvent e)
if(e.getSource==button)
ConnectServer cs=new ConnectServer();
// I want to stop here until the connection to server is finished but in the same time to repint itself if necessary
connection=cs.getConnection();
Thank you!

Unfortunately this has nothing to do with JDBC.
Basically you have two things that need to happen at the same time. So you need two threads. And a way to communcate between them. One thread waits for the connection and sets a flag when it it waiting and when it is done. The other thread reads that flag.
