JOptionPane dialog - always toFront

Is there any way to insure that a dialog issued from an application will
always come to front when executed from within an app?
I tried using the toFront() method of frame with mixed results...
If nothing is happening on desktop it seems to work but if I'm doing something
else it doesn't. I need this dialog to grab attention when executed
thanks for any help - JP

If you want the dialog to "stop" the application untill the user interacts in any way with the dialog and press some kind of "Acept" or "Cancel" button mke it modal:
new JDilog(frame_parent, true)
this line makes a modal (it's modal because of the second argument) dialog wich will be allways on top of the Frame frame_parent until it's disposed.
Hope it helps.

Custom Runtime Error Dialog Always showing

Hi,
(TestStand 2.0.1f1)
Using the Callback based on the example C:\TestStand\Examples\Callbacks\PostStepRuntimeErrorCallback\ErrorHandlerExample.seq.
The error dialog always appears. I was expecting from the comment in the Set ErrorReport Flag that the Dialog would not appear again. (Comment: If this flag is set, TestStand does not send a UIMsg_BreakOnRunTimeError event to the GUI. This step sets the flag to prevent the GUI from displaying a runtime error dialog because this callback has already displayed a runtime error dialog to the user.)
When you use the default Error Reporting, you can check a checkbox so that Dialogbox is not seen again for the same execution. I was expecting the same thing from the SequenceFil
ePostStepRuntimeError callback.
Any clues as to whats going on.
See attached example.

Hi,
In the Programmer Help for DisplayRunTimeErrorDialogEx method it says
"dontShowAgainForExecution Boolean Returns whether the user wants this dialog box to appear again if another run-time error occurs in the current execution. If this value is true, set Execution.RTEOptionForThisExecution to specify what to do on a run-time error for this execution."
Now I have tried setting each of the RTE Options (except the Display Dialog) to try get the same effect as not using the Callback for runtime errors when it comes to ignoring all further errors. Nothing seems to work as expected. So whats the engine doing extra thats not detailed in the Programmer Help or the examples provided.

JOptionPane show Message Dialog always on top found a Solution

just thought of a solution for the age old java problem with message boxes / dialogs / input .
It's funny when you google it you'll find like a million people asking for a solution but none or very few that gives an answer that works.
this is probly not a new solution but i came up with this yesterday and thought i would "share".
dunno why the java developers hasnt made a always on top function for this since there seems to be a very high demand for it.
this hax will hopefully work at all times.
hope google will find this thread, i searched for a solution yesterday and found none? which is surprising and im a pro googler too.
import javax.swing.*;
public class main{
     public static void main(String args[]){
          JFrame j=new JFrame();
          j.setAlwaysOnTop(true);
          j.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          j.setVisible(true);
          j.setVisible(false);
          JOptionPane.showMessageDialog(j,"hi");
          System.exit(0);
}

I didn't realize it was an "age old problem." The JOptionPane's showXXX methods just show an ordinary modal dialog. If you want to set the alwaysOnTop property of said dialog then you just need to obtain a reference and call the method in question.
JOptionPane op = new JOptionPane("hi",JOptionPane.INFORMATION_MESSAGE);
JDialog dialog = op.createDialog("Message Dialog");
dialog.setAlwaysOnTop(true); //<-- this line
dialog.setModal(true);
dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
dialog.setVisible(true);No need for an intermediate frame.

In Dual Monitor setup, with Thunderbird not in main monitor, the some dialogs always shows in other monitor

I have a three monitor set up. I have Thunderbird running in the right monitor. My main monitor is the middle one. Dialogs, such as Spell check, Activity Monitor always show up in the main window (not the one with Thunderbird) in the upper left hand corner.
It happens on Windows Vista and Windows 7 Professional.
I have Thunderbird version 24.3.0

Some dialogs when moved, stay moved. Others do not. The ones that frustrate me are those that are Centered and therefore show up split across my two monitors.

Customized KeyboardFocusManager problems with JOptionPane-Dialogs

Hi,
I have a problem I'm not able to solve: With Java 1.4.2 unter Linux, as well as all newer Java Versions (1.4, 1.5, 1.6) under Windows, dialogs created by JOptionPane.showXXXDialog do not react to keyboard events like <Tab> any more when using a customized KeyboardFocusManager. Java 1.5 and 1.6 under Linux work fine.
Here is what I did:
I have a JFrame and want some customized focus control when navigating through the Frame with <Tab>. Therefore I've implemented a class
public class EfaFrameFocusManager extends DefaultKeyboardFocusManagereand said in the main JFrame:
EfaFrameFocusManager myFocusManager = new EfaFrameFocusManager(this,FocusManager.getCurrentKeyboardFocusManager());
FocusManager.setCurrentKeyboardFocusManager(myFocusManager);The constructor of my EfaFrameFocusManager stores the JFrame (this) and the original KeyboardFocusManager (2nd arg) for later use. Within my own FocusManager, I've implemented the method
public void processKeyEvent(Component cur, KeyEvent e)which is checking whether the desired Frame (efaFrame) is currently active or not. If it is active, it's performing my customized operations which is working well. If it is not active (e.g. because a dialog created with JOptionPane.showConfirmDialog() is open), it should perform default actions. So I said within processKeyEvent:
if (!efaFrame.isActive()) { // efaFrame is the previous "this" arg
fm.processKeyEvent(cur,e); // fm is the previously stored CurrentKeyboardFocusManager
return;
}Instead of invoking processKeyEvent on the original KeyboardFocusManager fm, I also tried super.processKeyEvent(cur,e);, but without any change in behavior.
As I said before, this is working well under Java 1.5 and 1.6 with Linux.
However, it is not working unter Windows (any Java version I tried, including 1.4, 1.5 and 1.6) and also not unter Linux with Java 1.4. With these combinations, dialogs created by JOptionPane.showXXXDialog(...) do not respond to the <Tab> key. I do see that my own FocusManagers processKeyEvent method is invoked, and I also see that it invokes the one of the original FocusManager, but the Dialog doesn't react.
What am I doing wrong?
Nick.

I have a JFrame and want some customized focus control when navigating
through the Frame with <Tab>. sounds like you should be doing this via a FocusTraversalPolicy

Growing a JOptionPane dialog vertically

I am writing a simple JPanel for use within message dialogs.
Just wanted to add "more details" functionality really, for error dumps etc.
I've so far used this with JOptionPane:
     DetailsPanel detailsPanel = new DetailsPanel();
     detailsPanel.setMessage("Some error occurred");
     detailsPanel.setMessageDetails("Error dump details, stack trace, blah blah...");
     JOptionPane.showMessageDialog(frame, detailsPanel, "ERROR", JOptionPane.ERROR_MESSAGE);
However, when the button is clicked to display the extra details, the dialog doesn't resize to account for the extra text. I'm using a GridBagLayout manager, but previously had a BorderLayout. Neither seem to work. Have tried adding to a frame manually, same effect. Tried explicitly resizing the panel and parent, revaliding, invalidating, repainting blah blah.
Am I missing something obvious? Thanks for any help. Andy.
Here is the class:

          String newButtonText = detailsHidden ? MORE_DETAILS : LESS_DETAILS;
          detailsButton.setText(newButtonText);

Pass in the java.awt.Window reference in the DetailsPanel constructor. Then, when the user clicks the "Details" button, call window.pack( ). This will make the frame/dialog resize.
From your code:
private Window window ;
public DetailsPanel(JFrame window)
super();
this.window = window ;
String newButtonText = detailsHidden ? MORE_DETAILS : LESS_DETAILS;
detailsButton.setText(newButtonText);
window.pack( ) ;
}

Dialog always visible in top ???

hi,
i would like to display a dialog not modal, but always visible in top, even when its looses focus and other "nomal" dialogue are displayed, as a "color palette" dialogue or something like that, can you please tell which class is more suitable for this purpose, and if somebody has always coded this kind of dialog, i am interrested, thanks for your help

Specify the "parent" JFrame when creating the JDialog.

Dialog always in front

Hello,
how can I create a Dialog, that has always the focus and is always in front until it is closed.
Greetings from Cologne!
Marcel!

You want a modal dialog...see http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Dialog.html
You can use a constructor that allows you to set modal to true or call setModal(true)

Mnemonic in JOptionPane dialogs

In the dialogs opening with JOptionPane.showConfirmDialog(...) There are mnemonics 'Y' & 'N' set for Yes & No options resp.
Yes option can be chosen with Alt+Y & No option with Alt+N
Is there any WorkAround that by just pressing 'Y' option Yes is selected. (like there with option dialogs in windows).

How to get handle to JOptionPane dialog

Hi,
I'm working on a gui application which can generate dialogs when errors occur.
The problem I have, is the following :
Somewhere in the process, we show an info message this way :
JOptionPane.showMessageDialog((Component)parent, "This request may take up to 30 seconds...");Later on, another thread can generate an error message to inform the user that there was an error while processing the request. In this case, the first info dialog should be removed automatically (in case the user didn't close it yet).
From the thread, I have access to the parent object which is a JInternalFrame object.
Is there any way I can access the info dialog from the JInternalFrame object?
Thanks very much for your help!

check out [url http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/ProgressMonitor.html]javax.swing.ProgressMonitor which I think would fit your needs better than JOptionPane.
However, if you still want to use JOptionPane, check out it's [url http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JOptionPane.html]API spec, which includes how to access the JDialog directly (see the bottom of the class description).

More and more JOptionPane dialogs

weirdest problem I've ever had.. so far..
applet works fine in applet viewer.. and in browser
thing is.. I have a button to save to database.. works fine.. when saved I used a JOptionPane to show a message with something like "save completed" all works..
problem starts when you leave the page.. go to another page.. there the applet gets loaded with diffrent parameters.. and then save that one.. now you'll get 2 JOptionPanes.. with the same message..
go to some other page and save again and you'll get 3.. etc..
JOptionPane.showMessageDialog(null, "De flowchart is opgeslagen!", "Opgeslagen", JOptionPane.INFORMATION_MESSAGE);that's the optionpane.. gets called when the loop for saving to database is done..
**EDIT**
hmm.. this is interesting.. same problem 3 years ago

Hi SLaGFYmanny
Could you please start a new thread for your question instead of posting in an existing thread?
Then you can provide more information like your operating system and installed extensions and installed plugins.
*[[/questions/new start a new thread]]
*[[/kb/Using+the+Troubleshooting+Information+page]]
You can try basic steps like these in case of issues with web pages:
Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
*Hold down the Shift key and left-click the Reload button
*Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
*Press "Command + Shift + R" (Mac)
Clear the cache and cookies only from websites that cause problems.
"Clear the Cache":
*Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Do you think JOptionPane dialogs force garbage collection afterwards?

I ask because I've made a nested static class to implement my own file selection tool; the problem is that each time I call it the old JPanel is being recalled and so the components get re-added to it each time it's called, resulting in n versions of each file for every n times you open it.
I'm running myDialog.dispose() upon exiting, so is my only option now manual garbage collection? How could I force it to be garbage collected? Because System.gc() seems to have no effect.

Strictly speaking there is no way to force garbage collection, so, no, JOptionPane will not be doing it.
You almost certainly have a leak in your code. Post it and we may be able to help.

How to set dialog to tofront with out using modal?

i'm using toFront() method in my application in focusgained & window activated but it is not working on solaris.what to do?

Prepaid cards are not available in New Zealand since the iTMS isn't available there. The only way you could purchase from the iTunes Music Store would be of someone in a country that has one were to purchase a card in that country, send it to you, and allow you to set up an account using their mailing address.

Custom Dialogs - JOptionPane

Hi Guys,
I was after a quick bit of advice. I've written a small routine which handles the JOptionPane dialog when a user wants to delete some files/folders from within my app. I originally had a "showConfirmDialog" type dialog, but I also needed a "Yes to All" button too (for multiple selections). In essence its a YES_NO_CANCEL_OPTION - with an added "Yes to All" choice. I couldn't find a YES_YESTOALL_NO_CANCEL option in the "optionType" parameter in the Docs.
Heres what I've got...
protected int deleteFileCheck(File theFile) {
String fileOrFolder;
fileOrFolder = theFile.isDirectory() ? "folder" : "file";
Object[] options = {"Yes", "Yes to All", "No", "Cancel"};
return JOptionPane.showOptionDialog(null,theFile.toString()
+ "\n" + "Are you sure you want to delete this "
+ fileOrFolder + "?",
"Delete files from this project",
JOptionPane.DEFAULT_OPTION,
JOptionPane.WARNING_MESSAGE,
null, options, options[0]);
which returns -1 for "close", 0 for "yes", 1 for "yes to all", 3 for "no" and 4 for "cancel". This seems to work okay.
Is this the best way to do this??
I'm just double checking really...
Many thanks in advance.

Thanks for replying. I'll try to address your questions.
- Why restrict the design to having only one instance
of the frame? What purpose or requirement does that
fulfill?The app has a single JFrame that serves as the main window for the application. It implements an MDI desktop. Since the app is capable of handling multiple documents, there's no need for other instances of the main JFrame.
You're still free to invoke another instance of the app, but that will be in its own JVM with its own singleton.
- I think you pointed out your problem without
realizing it - why is the frame being passed around
to a bunch of methods? Who controls the frame? The app has many classes that subclass JDialog. JDialog's constructor expects a reference to the Frame or Dialog that owns it. I could use null here, but it's a personal preference to include it if possible.
The frame controls itself. For example, when the user takes some action that requires adding a new JInternalFrame, the code calls MyMainClass.getMDIDesktop().addInternalFrame() (assuming getMDIDesktop() is left as a static method; if not, the call becomes MyMainClass.getInstance().getMDIDesktop().addInternalFrame()).
- Should the controller of the frame provide
it on demand (accessor) instead of handing it off to
everyone to use for their own purposes? I guess I don't understand how what you're suggesting is substantially different than what I'm proposing. The (singleton) controller of the frame (which happens to be the frame itself) provides a reference (via .getInstance()) to whoever needs it -- rather than passing it explicitly.
- Who's creating all these dialogs such that they
need their own reference to the frame - why isn't it
the same class that controls the frame?The reference is often just to establish parentage, but also to allow various dialogs access to methods to create new internal frames/update existing internal frames/etc.

Fronting standard dialogs

My custom dialogs (derived from JDialog) have a window listener which overrides the windowActivated and windowDeactivated methods. These methods call toFront, and my dialog always stays on top of its owner.
My problem is how to do something similar with standard dialogs. I often call JOptionPane.showMessageDialog and JColorChooser.showDialog, and they work great, except that they are not fronted when their owners are fronted. These dialogs don't have an addWindowListener method like JDialog, so I can't solve my problem like I do with my custom dialogs. I hope you can give me a hint on how to keep standard dialos fronted.
Thanks.

demo:
import java.awt.*;
import javax.swing.*;
public class MyApplet extends JApplet {
    public void init() {
        JTextArea area = new JTextArea();
        for(Component comp = this; comp != null; comp = comp.getParent()) {
            for(Class cls = comp.getClass(); cls != null; cls=cls.getSuperclass()) {
                area.append(cls.toString());
                if (cls.getSuperclass() != null)
                    area.append(" --> ");
            area.append("\n");
        getContentPane().add(new JScrollPane(area));
}

JOptionPane dialog - always toFront
