Question about the result of calling JDialog.setAlwaysOnTop(true)
Let's use these two small code snippets for reference.
Sample 1
JDialog d = new JDialog(myFrame, "Dialog Title");
d.setModal(true);
d.setAlwaysOnTop(true);
d.setVisible(true);Sample 2
JDialog d = new JDialog(myFrame, "Dialog Title");
d.setModal(true);
d.setVisible(true);Using #1 I get a modal dialog that is on top of ALL other windows, even things like Firefox and Thunderbird (two greats apps).
Using #2 I get a modal dialog that is not on top of other apps when the other apps gain focus.
I would like to avoid using #1 so I don't annoy my users with popup windows that are always on top of other app windows. However, if I use #2, sometimes the modal dialog can "fall behind" it's parent frame, making it very difficult to ever get back. Since the parent frame (myFrame) is waiting on a modal dialog to close, the frame is not movable or minimizable. The modal dialog is hidden behind the parent frame, which makes it hard to get unless I do something like Alt-Tab to cycle through the current open windows. I can't expect my users to know or use the Alt-Tab capability.
Any suggestions?I found the problem. I wasn't passing in 'myFrame' as an argument. This resulted in a modal dialog that had no parent frame. That allows the dialog to fall behind the main application frame. So, as long as the parent frame is specified, the problem situation I described can't happen.

hi, i have a JDialog that needs to be modal,
in the jdialog is a JList that gets filled up with a DefaultListModel after the dialog is instantiated, the problem now is when i have setModal ( true ), the JList doesn't fill up ?
Anyone know a solution to this ?Does your code look something like this?
JDialog dialog = new JDialog(parent);
dialog.show();
dialog.fillJList();
If so, it won't work because the line dialog.fillJList() is not executed until the dialog is closed. Make sure you populate the JList in the constructor of the dialog. -

Key-enable buttons on a JOptionPane
Hi,
The existing code in my Application uses a JOptionPane static method = JOptionPane.showOptionDialog() to create a dialog box.Is there any way I can key-enable the buttons on the dialog created by this method.
public int createAndShowGUI() {
if (!issuesPanel.hasIssues())
return -2; //TODO make constant
else {
//Custom button text
String[] options = should_continue ? new String[] {returnText, continueText} : new String[] {returnText};
int optionButtons = should_continue ? JOptionPane.OK_CANCEL_OPTION : JOptionPane.CANCEL_OPTION ;
log.info("IssuesOptionPane displayed - " + title);
int optionChosen = JOptionPane.showOptionDialog(parent,
issuesPanel.createAndGetIssuesPanel(),
title,
optionButtons,
JOptionPane.PLAIN_MESSAGE,
null, //don't use a custom icon
options, //titles of buttons
null); //no default selected button
String buttontext = optionChosen == CLOSE ? "X" : options[optionChosen];
log.info("User clicked on the " + buttontext + " button");
return optionChosen;
I see that there is no way to get a handle on the JButtons created by the JOptionPane.So, one work around that I tried is to create a JPanel, add JButtons , set Input Map, set Action Map ( to add key bindings ) on it.Then create a JDialog and pass this JPanel to the dialog using setContentPane
private static void createAndShowGUI(){
JButton bookingButton=new JButton(bookStr);
JButton returnButton=new JButton(returnStr);
bookingButton.addActionListener(new BookAction());
returnButton.addActionListener(new ReturnAction());
JPanel panel=new JPanel();
panel.add(bookingButton);
panel.add(returnButton);
panel.setActionMap(initActionMap());
initAndSetInputMap(panel);
JDialog dialog=new JDialog();
dialog.setSize(400,100);
dialog.setModal(true);
dialog.setContentPane(panel);
dialog.addPropertyChangeListener(indicator,listener);
System.out.println("step 1" );
dialog.pack();
System.out.println("step 2");
dialog.setVisible(true);
But the problem that I am facing here is that the property change events triggered by the code inside the actionPerformed methods is not getting capturesd by the listener attached to the JDialog.
Any thoughts?

Problem with socket object writing
hi,
I made this little programm , with a class point , a server and a client.
I try to send via the socket several point object.
If send differents objects ( with several new point(... )) it works fine , but if i send the same object changing only the properties it doesn't work. Changing are not applicate.
Here is the code.

I doesn't work , i receive a point with 50,50 ( the first one ) four times ...If you can explain me me why and what can I do ...
Thx.For ObjectOutputStream, multiple references to a single object are encoded using a reference sharing mechanism so that graphs of objects can be restored to the same shape as when the original was written. State of a object will be recorded so that the ObjectOutputStream doesn't writes the same object to the outputstream when the object was refered by multiple references. So, when you tried to write the same object agains into the ObjectOutputStream, the ObjectOutputStream doesn't write the object, but passed the as a reference to the outputstream... In this case, on the other side, the ObjectInputStream will receive this reference and it will return the reference of this object (which is previous created when this object was passed over on the 1st time). This caused the ObjectInputStream will return a "unchanged" object even your object have changed before you write it agains to the ObjectOutputStream.
My explaination maybe not that good... hope you can understand... :) -
Memory problem with JTextFields
Hello,
I have a wierd problem with JTextField and the memory.
I need to fill a JPanel with different Components (including JTextFields), then do some calculation, remove the Components and filling the JPanel again.
When i so this too often my i get an OutOfMemory Exception. I narrowed to problem down and wrote a small sample program to demonstrate the problem.
When i call the method doIT (where the Panel is repeatedly filled) from the main-function everything works fine, but when it is called as a result from the GUI-Button-Event the memory for the JTextFields is not freed (even the call of the Garbage collector changes nothing)
When i only use JButtons to fill the Panel everything works fine.
Has anyone an idea why this problem occurs and how i can work around it?
[Edit] I tested it whith java 1.5.0_06, 1.5.0_11, 1.6.0_02
Thanks

marcvomorcThank you for your answer,
In this sample the programm does not run out of memory. But when you look at the output you see, that in the first run (direct call) the memory ist freed immediately when tha panel is cleared but in the second run (from the Button) the memory usage is getting bigger and bigger. Wenn you change the number of components to 2000 (4000)
// Fill Panel with components
for (int i = 0; i < 2000; i++) {
// The Buttons seem to be released without any problem
//... ...and use the default memory settings (69mb heap) the programm runns out of memory.
I get the following output:

Saving parameters entered in a gui dialog to be used in the main panel
Hi,
I'm having a nightmare at the moment.
I've finished creating a program for my final year project, that is all comand line at the moment.
i'm required to design a GUI for this. i've started already and have a main panel that has a few buttons one of which is a setParameters button. which opens up a file dialog that allows the user to enter parameters that will be used by the main panel later on.
I'm having trouble imagining how these parameters will be accessed by the main Panel once they are saved.
At the moment, without the GUI i have get and set methods in my main program which works fine. Is this the kind of thing i'll be using for this?
my code for the parameters dialog
public class Parameters extends JDialog
private GridLayout grid1, grid2, grid3;
JButton ok, cancel;
public Parameters()
setTitle( "Parameters" );
setSize( 400,500 );
setDefaultCloseOperation( DISPOSE_ON_CLOSE );
grid1 = new GridLayout(7,2);
grid2 = new GridLayout(1,2);
JPanel topPanel = new JPanel();
topPanel.setLayout(grid1);
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(grid2);
ok = new JButton("OK");
ok.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//when pressed i want to save the parameters that the user has entered
//and be able to access these in the RunPanel class
cancel = new JButton("Cancel");
cancel.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//when pressed just want the Jdialog to close
buttonPanel.add(ok);
buttonPanel.add(cancel);

JTextArea clonalRate = new JTextArea();
JTextArea stimulationValue = new JTextArea();

CheersWhat you need is my ParamDialog. I think it could be perfect for this sort of thing. There are a few references in it to some of my other classes namely
StandardDialog. Which you can find by searching for other posts on this forum. But if you'd rather not find that you could just use JDialog instead
WindowUtils.visualize() this is just a helper method for getting things visualized on the screen. You can just use setBounds and setVisible and you'll be fine.
You are welcome to use and modify this code but please don't change the package or take credit for it as your own work.
If you need to bring up a filedialog or a color chooser you will need to make some modifications. If you do this, would you mind posting that when you are done so that myself and others can use it? :)

Multiple Popups when I want one at a time
Hi, I'm writing a gui, and I am having difficulties managing popups. Some of my tasks require a password, so I made a task performer class that prompts for a password and performs the given task with that password. Now the problem is, right after I call the performTask method (which initializes the PasswordPrompt) I create a yes or no JOptionPane dialog. Both the PasswordPrompt and the JOptionPane dialog appear at the same time when I want the JOptionPane to only appear after the PasswordPrompt has been disposed. The task performer adds itself as a listener to the password prompt, which notifies the performer once the password has been submitted.
I'm not going to write out all of my code, but here is the general idea.
public class TaskPerformer {
public void performTask() {
// Opens a password prompt that I wrote.
// The TaskPerformer is passed to the password prompt
/* When the okay button is pressed in the password prompt
* this method is called with the password entered by the user
public void give password(String password) {
//The task is actually performed here.
public class MyMain {
public static void main(String [] args) {
TaskPerformer tp = new TaskPerformer();
tp.performTask();
if(JOptionPane.showConfirmDialog(null, "Would you like mashed Potatoes with your turkey?") {
System.out.println("yay mashed Potatoes!");
}I'm sure I need to use something like wait() and notify(), but I'm really not familiar with these.I think you can solve your problem if you choose to use a modal dialog as the container
for your password-entry-panel.
See example below:
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JOptionPane;
import javax.swing.JPasswordField;
public class Test
public static void main(String[] args)
final JDialog dlg = new JDialog();
/* if you set modality to 'false', the JOptionPane will come immediately,
* when 'true', The JOptionPane will come AFTER you click ok */
dlg.setModal(true);
dlg.getContentPane().add(new JPasswordField(40), BorderLayout.NORTH);
JButton okButton = new JButton("ok");
okButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
dlg.dispose();
dlg.getContentPane().add(okButton);
dlg.pack();
dlg.setLocationRelativeTo(null);
dlg.setVisible(true);
JOptionPane.showMessageDialog(null, "hi there!");
}Hope this helps! -

How can i only allow the activation of the JDialog on top?
Hi to all,
i have a problem with a mask swing
Well, my problem is this:
In a window, when i click on save button, it's open a customizing JDialog. But i would like how i can deny a click out of this JDialog, that is on top.
In other words, in this situation, with a jdialog on top, if the user click once again on the save button or out of this jdialog, the jdialog must stay on top and active.
How i can this?
Please help me!!
the code that realize my class is this:
public class ConsegnaOrdineDialog extends JDialog implements ActionListener {
private JOptionPane optionPane;
private String dataOrdine;
private JButton si, no;
private JTextField dataConsegna;
public ConsegnaOrdineDialog(String dataOrdine) {
this.dataOrdine = dataOrdine;
dataConsegna = new JTextField();
si = new JButton("Si");
no = new JButton("No");
si.addActionListener(this);
no.addActionListener(this);
JPanel panel = new JPanel();
panel.setLayout(new BorderLayout(5, 10));
panel.add(dataConsegna, BorderLayout.NORTH);
panel.add(si, BorderLayout.WEST);
panel.add(no, BorderLayout.EAST);
Object[] options = {panel};
optionPane = new JOptionPane("La data �:",

I posted a question yesterday about jdk1.6 being slow on SUN under certain conditions. I was able to reproduce the problem with a simple program that I attach. Here's the scenario. The interface has two buttons. If you click "Show Dialog" the dialog window will display immediately. If you click "Show Frame" first and then select "Show Dialog" you'll see that there is a significant delay before the dialog is displayed. It seems that the setModal line for the dialog is causing the trouble here. Note that I've only seen this delay on a SUN and it doesn't happen on jdk1.5.
Does anyone have an idea as to what might be happening here?

Problem with a template method in JDialog
Hi friends,
I'm experiencing a problem with JDialog. I have a base abstract class ChooseLocationDialog<E> to let a client choose a location for database. This is an abstract class with two abstract methods:
protected abstract E prepareLocation();
protected abstract JPanel prepareForm();Method prepareForm is used in the constructor of ChooseLocationDialog to get a JPanel and add it to content pane.
Method prepareLocation is used to prepare location of a database. I have to options - local file and networking.
There are two subclasses ChooseRemoteLocationDialog and ChooseLocalFileDialog.
When I start a local version, ChooseLocalFileDialog with one input field for local file, everything works fine and my local client version starts execution.
The problem arises when I start a network version of my client. Dialog appears and I can enter host and port into the input fields. But when I click Select, I get NullPointerException. During debugging I noticed that the values I entered into these fields ("localhost" for host and "10999" for port) were not set for corresponding JTextFields and when my code executes getText() method for these input fields it returns empty strings. This happens only for one of these dialogs - for the ChooseRemoteLocationDialog.
The code for ChooseLocationDialog class:
public abstract class ChooseLocationDialog<E> extends JDialog {
private E databaseLocation;
private static final long serialVersionUID = -1630416811077468527L;
public ChooseLocationDialog() {
setTitle("Choose database location");
setAlwaysOnTop(true);
setModal(true);
Container container = getContentPane();
JPanel mainPanel = new JPanel();
//retrieving a form of a concrete implementation
JPanel formPanel = prepareForm();
mainPanel.add(formPanel, BorderLayout.CENTER);
JPanel buttonPanel = new JPanel(new GridLayout(1, 2));
JButton okButton = new JButton(new SelectLocationAction());
JButton cancelButton = new JButton(new CancelSelectAction());
buttonPanel.add(okButton);
buttonPanel.add(cancelButton);

Edited by: spyboost on Jul 24, 2008 5:38 PMWhat a silly error! I have to call Integer.parseInt instead of getInt. Integer.getInt tries to find a system property. A small misprint, but a huge amount of time to debug. I always use parseInt method and couldn't even notice that silly misprint. Sometimes it's useful to see the trees instead of whole forest :)
It works perfectly. Sorry for disturbing.
