Non-modal JDialog hides its JFrame "owner"
I'm writing my first significant swing application. It has a JFrame that launches a JDialog. When constructing the JDialog, I have the JFrame as the owner and set it to be non-modal. The dialog is indeed non-modal, since it allows me to click on the JFrame and run it. However, if the two windows overlap, the JDialog is always on top, covering the JFrame, even if the JFrame has focus. This can make it difficult to effectively work with the JFrame while the JDialog is on the screen.
There must be a simple solution to this, but I haven't discovered it yet. Any ideas?
Thank you so much for your reply. I just confirmed that passing null to the JDialog does indeed allow the JFrame to overlay it. However, now if I minimize the JFrame, the JDialog stays up. I'd prefer that it go disappear with the JFrame. Is there a way to "have it both ways"? That is, Is there a way to make the JDialog go away when the JFrame is minimized, but still make it possible for the JFrame to overlay the JDialog?
Thanks again for the original reply.
TIA on this one, too!

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,
BhaskarHi 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.

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.
My code.

Change a modal JDialog to non-modal JDialog
I created a modal JDialog initially, for some result i need change it to a non-modal JDialog, is there any set modal command can do it??
Nope.
The reason is because of program flow:
System.out.println("first line");
JDialog dialog = new JDialog(modal);
dialog.setVisible(true); // blocks this flow if and only if modal is true
System.out.println("second line");
Try putting a button in the dialog which prints out "button pressed".
If you press the button each time before closing the dialog you will get:
when modal is true:
first line
button presed
second line
when modal is false:
first line
second line

JButton on XP non-modal Jdialog doen't work.
I recently upgraded from 1.3 to 1.4 while upgrading my OS from NT 4.0 to XP.
In a stand-alone application I have non-modal JDialog's that are launched as threads so that I can have multiple instances of them running simultaneously. There are JButton's on the JDialog's which no longer respond to any mouse events even though I can execute them via the keyboard using the tab and enter keys. They work just fine under 1.3 or if I make them modal.
Any thoughts?Hello,
Issue is-
There are JButton's on the JDialog's which no longer respond to any mouse events even though I can execute them via the keyboard using the tab and enter keys. They work just fine if I make them modal.

Non-modal JDialog is not painted and blocks the GUI
I have developed a GUI that's basically a JFrame with a JDesktopPane.
The user can, via a menu item, pop up a JDialog that contains some JLists and then select some value from it. Once he/she has done the selection and clicks on OK, the dialog disappears (data processing is then done in the main GUI) and comes back once a specific event has happened. The user then selects other data and so on, until he/she clicks on Cancel, which definitely disposes of the JDialog.
The graphics of the JDialog are build in the class constructor, which does a pack() but does not make the dialog visible yet. The dialog appears only when doSelection() is called.
/** Called the first time when user selects the menu item, and then
when a specific event has happened. */
public Data[] doSelection() {
dialog.setVisible(true);
// ... Code that reacts to user's input. Basically, the ActionListener
// added to the buttons retrieves the user's selection and calls
// dialog.setVisible(false) if OK is clicked, or calls dialog.dispose()
// if Cancel is clicked.
}Now, everything works fine if the JDialog is modal, but if I make it non-modal only the window decorations of the JDialog are painted, and the control doesn't return to the main GUI. Calling doLayout() or repaint() on the doSelection() has no effect. How can this be fixed?
I hope I have been able to explain the problem satisfactorily, I could not create a suitable SSCCEE to show you. Thanks in advance for any hint.Ok, I've taken some time to think about this problem and I've modified the code a bit.
Now the dialog shows itself and is responsive (i.e. its JLists can be operated), but the Ok button does not close the dialog as I'd want. I believe that I'm messing up things about threading, and the operations in actionPerformed() should be carried out in another thread, if possible.
Thanks in advance for any hint / suggestion / comment / insult.
private Data[] selection;
/** Constructor */
public MyDialog() {
// ... Here is the code that builds the dialog...
dialog.setModal(false);
dialog.pack();
// Note that the dialog is not visible yet
public Data[] doSelection() {
operatorAnswer = NONE_YET;
dialog.setVisible(true);
while (operatorAnswer == NONE_YET) {
try {
wait();
} catch (InterruptedException e) { }
return (operatorAnswer == OK ? selection : null);
public void actionPerformed(ActionEvent evt) {
if (okButton.equals(evt.getSource())) {
operatorAnswer = OK;
retrieveSelection();
dialog.setVisible(false);
else if (cancelButton.equals(evt.getSource())) {
operatorAnswer = CANCEL;
dialog.dispose();
private void retrieveSelection() {
// ... Here is the code that retrieves selected data from the dialog's JLists
// and stores it in the "selection" private array...
notifyAll();

I have created a JDialog which is non-modal. This dialog has lot of controls viz. buttons, combo box etc. This dialog is launched on clicking a button placed on panel. Surprisingly, when the dialog is launched, all components are disabled. Is there any way I can make these enabled? There is no line of code which has been done to change the behaviour of these components. They work fine if I make the dialog modal. Please advice.
Thanks.
The constructor for creating the dialog is pasted as below:
public AbstractDialog(Frame owner, String title, boolean isModal) {
super(owner, title, isModal);
JRootPane rootPane = getRootPane();
Action escapeKeyAction = new AbstractAction() {
public void actionPerformed(ActionEvent e) {
AbstractDialog.this.dispose();
rootPane.registerKeyboardAction( escapeKeyAction,
KeyStroke.getKeyStroke( KeyEvent.VK_ESCAPE, 0 ),
JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT );
UFSAFocusTraversalPolicy obj = new UFSAFocusTraversalPolicy ();
//obj.setImplicitDownCycleTraversal(false);
this.setFocusTraversalPolicy(obj);
this.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
this.setFocusCycleRoot(true);
this.addWindowListener(windowAdapter);
The isModal passed is false. -
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:

TristanHi,
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

A non-modal, but "always on top" JDialog
Hi everyone,
In an applet I am creating, I need to create a non-modal JDialog which stays on top whenever its open. The reason this JDialog is required to be non-modal is that I need the main applet window to be able to react to events and reflect changes in the non-modal JDialog.
I was wondering how this can be achieved.
To summarize the problem:
How can you have a JDialog whose modal property is "false", but stays on top of the applet window.
This problem has been bugging me for quite a while now, so any pointers will be appreciated.
Thanks,
AlanHere is how you do it in an applet (as opposed to JApplet):
* Browser sniffer *
boolean isNN4=false,isNN6=false,isIE=false;
Frame F;
JSObject window=JSObject.getWindow(this);
JSObject document=(JSObject)window.getMember("document");
String tmp=document.getMember("all").toString();
if (tmp.equals("undefined")) {
tmp=document.getMember("getElementById").toString();
if (tmp.equals("undefined")) isNN4=true; // Netscape Navigator 4
else isNN6=true; // Netscape Navigator 6
} else isIE=true; // MS Internet Explorer
if (isIE) {
F=new Frame();
} else F=(Frame)getParent();
now you have a frame for use with the Dialog (not JDialog) method
...Just add the code shown above in the init method of your applet.
Good Luck!

JDialog Non Modal....Default button remains
I've created a non modal JDialog
By doing the following
1. Creating an object of JOptionPane(message, JOptionPane.ERROR_MESSAGE)
2. Adding the JOptionPane object to the ContentPane
3. Creating a button
4. Adding button("End Application") to ContentPane
5. Adding listeners to window and button
The result is a dialog
Message
ICON "OK" Button...............................NOT REQUIRED
"End Application" Button
I don't require the "OK" Button. Is there a way of removing this button. I need the dialog box to be modal so can't use showMessageDialog, rename "Ok" button to "End Application" etc.
Should I be taking a different approach ie Not adding JOptionPane to JDialog??
If the above isn't possible. Do you know where I can find the default error gif on error dialog boxes?
Kind regards,
JeanGet the error icon with UIMananger.getIcon("OptionPane.errorIcon"). It might throw exceptions while painting because it's expecting to be painting in a JOptionPane. Just catch and ignore the exceptions and it will paint alright.

How do I create a Modal JDialog (non-bypassable when visible)?
After customising a JDialog, I found that it is basically ignored after it has been created, by the main program. I've tried many ways to stop this from happening, searched the Java tutorial and googled it, but cannot find out how to do so. I have used the constructor for a modal Dialog:
JDialog(Dialog owner, String title, boolean modal)However, my methods are still treated like a non-modal Dialog, as they are ignored. Is there a certain method I have to call to make this Dialog modal (not able to be bypassed when made visible). If so then I would appreciate it if anybody could help, or perhaps point me along the right way.JDialog(Dialog owner, String title, boolean modal)How do you expect us to solve your problem based on a single line of code? Create a simple demo program that shows the problem
Here is a simple demo that works.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class DialogModal extends JFrame implements ActionListener
public DialogModal()
JButton button = new JButton("Show Dialog");
button.addActionListener( this );
getContentPane().add( button );
public void actionPerformed(ActionEvent e)
JDialog dialog = new JDialog(this, "Modal Test", true);
dialog.setSize(300, 300);
dialog.show();

JFrame frame = new DialogModal();
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frame.pack();
frame.setLocationRelativeTo( null );

Imitate modal dialog by non-modal
Hi
I'm trying to achieve modal dialog functionality by non-modal (i have reasons to do that), but I have encountered a real problem:
calling wait() from EDT is freezing everything. Below is source code, in most cases dialog is created inside action listener (in the EDT), so it is the source of problem:
public class TestMyDialog {
public TestMyDialog() {
final JFrame jFrame = new JFrame();
JPanel panel = new JPanel();
JButton button1 = new JButton("open dialog");
JButton button2 = new JButton("close");
button1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.out.println(SwingUtilities.isEventDispatchThread());
Object syncObject = new Object();
new MyDialog(jFrame, "title", syncObject);
try {
synchronized (syncObject) {
syncObject.wait();
} catch (InterruptedException ex) {
ex.printStackTrace();
System.out.println("dialog closed");
button2.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.exit(0);
panel.add(button1);
panel.add(button2);
jFrame.getContentPane().add(panel);
jFrame.setUndecorated(true);
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jFrame.pack();
jFrame.setVisible(true);
public static void main(String[] args) {
new TestMyDialog();
}And main class:
* Dialog that imitates modal dialog.
* @author ggg
@SuppressWarnings("serial")
public class MyDialog extends JDialog {
private Frame ownerFrame;
public MyDialog(Frame owner, String title, final Object syncObject) {
super(owner, title, false); // modal = false
this.ownerFrame = owner;
JButton button1 = new JButton("close dialog");
button1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
ownerFrame.setFocusable(true);
ownerFrame.setEnabled(true);
setVisible(false);
dispose();
synchronized (syncObject) {
syncObject.notifyAll();
add(button1);
ownerFrame.setFocusable(false);
ownerFrame.setEnabled(false);
setSize(300, 200);
setVisible(true);
} // end of constructor
}Any ideas would be highly appreciated.gimbal2 wrote:

Any ideas would be highly appreciated. What about... don't ever block the EDT?Why do you mean by don't block the EDT? I'm using wait() because I need the calling thread to stop for a while (close dialog) but unfortunately this thread is EDT in case of ActionListeners....

Problem with jDialog in a JFrame
Hello to everyone...i'm newby java GUI developer, and i've got a problem with a JDialog within a JFrame...
I made a JFrame which creates a new customized JDialog in his contructor, like this:
MioJdialog dlg = new MioJdialog(this, true);
dlg.setVisible(true);
...The "MioJdialog" class store his JFrame parent under a private attribute, in this way:
class MioJdialog {...
private Frame parent;
public MioJdialog (Frame parent, boolean modal){
this.parent=parent;
....}and here's the problem: when i try to close the parent JFrame with a command like this:
parent.dispose();
( in order to close the whole window), sometimes happens that the JFrame is still visible on the screen...and i don't know why...
got some hints?
thanks to everyone!

hi! i have ds problem.. how do u create a JFileChooser dialog that would only
be modal to its parent window and not to the entire application window...
pls. help.. =)If the chooser has a JDialog object as a parent component, you can get that object by some method in SwingUtilties, I think... then call setModal on it. But this will make it fully non-modal to all windows. You can't be selective about modal windows without some lower level system tweaking, I think. But generally, a file chooser is modal because usually you can't continue what you are doing til you pick a file or cancel.

i found this thread [http://forum.java.sun.com/thread.jspa?threadID=744269&messageID=4262681] but i dont really understand whats goin on, i dont need to know anything about the users interaction with this dialog box
thanks in advance
alexThe api gives an example. something like this has worked for me:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.SwingUtilities;
public class NonModalJOptionPane extends JFrame
public NonModalJOptionPane()
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JButton button = new JButton("Press me");
button.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent arg0)
JOptionPane myOptionPane = new JOptionPane("Hey, hey, my, my",
JOptionPane.INFORMATION_MESSAGE, JOptionPane.OK_OPTION);
JDialog dialog = myOptionPane.createDialog(
NonModalJOptionPane.this, "Rock and Roll Will Never Die");
dialog.setModal(false);
dialog.setVisible(true);
add(button);
pack();
setLocationRelativeTo(null);
public static void main(String[] args)
SwingUtilities.invokeLater(new Runnable()
public void run()
new NonModalJOptionPane().setVisible(true);
}
