InputVerifier and JOptionPane.showMessageDialog
Since I have intalled JDK 1.4. I have got the following Problem:
in the verify Method there is a call to JOptionPane.showMessageDialog
in order to show a error message if the input doesn�t match and before false is returned.
It doesn�t work anymore with 1.4. In case of error, the message Dialog is not coming up and the verify methodis just called in a endless loop.
try setting the InputVerifier to null before displaying the JOptionPane, then set it back after the JOptionPane.
textField.setInputVerifier(null)
JOptionPane.showMessageDialog(...)
textField.setInputVerifier(this)

InputVerifier and JOptionPane help please
I am trying to create an application and require to validate input fields. I have successfully written the code to use the InputVerifier class to validate the input but want to use a JOptionPane dialog to notify errors. This doesn't seem to work as the JOption Pane is treated as an attempt to shift focus from the field being validated (which calls shouldYieldFocus() which tries to show a JOptionPane which tries to shift focus .........). I have a temporary fix by using an disabled text field to display the message but it isn't very elegant. Anyone any ideas please ?
Did you get any solution?
I am also facing the same problem but with Jdk 1.4 only.
In Jdk 1.3 it's working fine.
Please let me know if u have any solution -
Font of JLayeredPane and color of JOptionPane.showMessageDialog
how can I change font from bold to regular and vise versa in Caption of JLayeredPane
and how can I change color of JOptionPane.showMessageDialog?
Thank YouGeorge, you have been extremely helpful. You don't know how much I appreciate your knowledge and patience.
1. Seems like going this option, we would be better served just making a web-based form. I'll pass that on to the Powers-That-Be.
2. Not to imply these folks are computer-illiterate, but the users completing the forms are plumbers, electricians, locksmiths, carpenters, etc. In fact, they get a good number of printed, hand-written, snail-mailed forms submitted. I really don't know the likelihood of getting these users to download and install Reader 11.
Again, thanks so much for your time and expertise.

Problem with Enter key and JOptionPane in 1.4
Hi,
I had a problem with an application I was working on.
In this application, pressing [Enter] anywhere within the focused window would submit the information entered into the form that was contained within the frame.
The application would then try to validate the data. If it was found to be invalid, it would pop up a JOptionPane informing the user of that fact.
By default, pressing [Enter] when a JOptionPane is up will activate the focused button (in most cases, the [OK] button) thus dismissing the dialog.
In JDK 1.3 this worked fine. But in JDK 1.4, this has the result of dismissing the dialog and opping it up again. This is because the [Enter] key still works on the frame behind the JOptionPane and thus tries to validate it again, which results in another invalid dialog msg popping up.
The only way to get out is to use the mouse or the Esc key.
Now, in the application I put in a workaround that I was not very happy with. So, to make sure it wasn't the application itself, I created a test which demonstrates that it still misbehaves.
Here it is.

}Does anyone have any solution to this problem?I know that focus management has changed alot.
Based on my experimentation a while back, in 1.4 it still believes that the JFrame is the window in focus, even though a JOptionPane is currently in front of it (unless I misinterpreted what was going on). Thus, the frame seems to get the keyboard event and re-invoke the action.

JOptionPane.showMessageDialog() - word wrapping exceptions?!
Hey ppl,
Probably a silly question...
I'm currently working with JDBC, and SQLexceptions can be very long! Currently displaying them in a JOptionPane.showMessageDialog() (as i guess most people do?), but being so long they cause it to span the whole screen & then some!
I looked through the JOptionPane API, but didn't spot anything that might help. Is there a way to get this exception to dispaly on multiple lines, kinda like word wrap in notepad?
Cheers for any suggestions.
JimI can't speak for other developers..But as for myself, I rarely if ever print error messages to the JOptionPane. Almost always, I print my error messages and the stack if necessary, to the ouput. This is either a command line window, console, log file, or output screen in an ide depending upon how you program. My code looks something like this.
catch(Exception e)
System.out.println(e.getMessage()); // Will print only the message property of the exception
e.printStackTrace(); // Will print the stack for more information
}Sorry I couldn't answer your question directly. Maybe someone else can. Hope I was helpful anyway. -
Change Button Name in JOptionPane.showMessageDialog
Hello,
I've written the following code that invokes a JOPtionPane messageDialog, when the delete button is hit in the following frame and the selectedItem in the JComboBox is Default.

}Hi,
yes, I've looked at the tutorials. But there is no way to change button title for JOptionPane.showMessageDialog. Only JOptionPane.showOptionsDialog provides you w/ that feature, becuz it provides the parameter in the method.
I was wondering if there was another way to do this for showMessageDialog. -
JOptionPane.showMessageDialog vs JOptionPane.showInternalMessageDialog
This is my first post to the message boards, so please don't be too hard on me if this is really obvious...
I'm trying to show a pop-up box with a message to indicate an error to the user; the JOptionPane.showMessageDialog works just fine, however when I use JOptionPane.showInternalMessageDialog, I get a NullPointerException being thrown by the L&F component(s) as follows (I'm currently running this as an applet via appletviewer):
Exception occurred during event dispatching:

I guess that I've really got two questions about this whole thing... 1) What could be causing the NullPointerException and 2) What is the real difference between JOptionPane.showMessageDialog and JOptionPane.showInternalMessageDialog?Here's the call that I'm using to the function -- sorry for not posting that originally...
JOptionPane.showInternalMessageDialog( this, getString( "Messages.NoPOsSelected" ), "Error", JOptionPane.ERROR_MESSAGE );Where "this" should be the applet itself, since this is being called from a function within the JApplet. -
JOptionPane.showMessageDialog auto closed by itself
Hi guys,
I"m facing a very weird issue. Our application is written in Swing and we encounter that the JOptionPane is automatically closed.
<code>
logger.debug( "Showing message dialog" );
JOptionPane.showMessageDialog( this,
"Some message" );
logger.debug( "Message dialog returned" );
</code>
In the logs we have found out that it printed both directly. The user didn't have the chance to click OK button.
We are using JDK 1.5.0_15, Windows XP Pro SP2
Thanks.You need to create a "Short, Self Contained, Compilable
and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't
guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting. -
JOptionPane.showMessageDialog ( ERROR_MESSAGE)
hi can anyone help...
i am using a
JOptionPane.showMessageDialog ( ERROR_MESSAGE)
to validate my input in some textfields... and when
there is an ERROR the merror message will pop up...
how to write the code so that when the user click the
OK button inside the pop-up msg , the button can
handle some functions as to reset some variable....??If you read the javadocs for JOptionPane you will find that the dialog you get from calling any JOptionPane.showXXXDialog method is modal. Consequently, when you have called showMessageDialog the current thread will be blocked until the user presses the OK button. So you can just put your reset handling code after the call to showMessageDialog, like the following little program demonstrates:
import java.awt.event.*;
import javax.swing.*;
public class OptionPaneErrorTest {
public static void main(String[] args) {
ApplicationFrame app = new ApplicationFrame();
app.setVisible(true);
private static class ApplicationFrame extends JFrame {
public ApplicationFrame() {
JButton btn = new JButton("Click Me");
btn.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, "This is an error message", "Error", JOptionPane.ERROR_MESSAGE);
System.out.println("This will get printed when the user presses the OK button");
getContentPane().add(btn);
pack();
}Hope this helps. -

Missing message on JOptionPane.showMessageDialog
Hi,
I created two JTrees and drew a line from a node in one tree to a node in another tree.
After the mouse was released, I showed a message using JOptionPane.showMessageDialog(null, message). The message was not displayed. But if I show the message dialog box before I draw the line,
the message is displayed.
Could someone point me the possible problems or any similar example code?
Thanks in advance!

JOptionPane.showMessageDialog(ConfigTab, "Configuration saved."); Is this called on the EDT? Or better still, can you provide an SSCCE that shows the behaviour?
Is this issue is due to java version?No. It is most likely due to broken code.
