Using JoptionPane.ShowInternalDialog

I'm using the following code to open an JInternalFrame as model from another JinternalFrame.
partNumberMaintenanceFrame = new PartNumberMaintenance_4_1 (this,null,data);
JPanel glass = new JPanel();
glass.setOpaque(false);
glass.setLayout(null);
glass.add(partNumberMaintenanceFrame);
mainDesktopFrame.setGlassPane(glass);
glass.setVisible(true);
partNumberMaintenanceFrame.setVisible(true);
Now, the problem is , When i try to use JoptionPane.ShowInternalDialog from the partNumberMaintenanceFrame the messagedialog goes behind the frame.
I guess this is bcoz i use glasspane. What shoup i do to make the dialog to show on the frame?
Thanks

You might need to post a little more code for people to help you.

Using JOptionPane to exit program & Using toString method

Hello,
In my program I have to use a toString method below
public String toString(Hw1NCBEmployee[] e)
        String returnMe = String.format(getStoreName() + "\n" + getStoreAddress() + "\n" + getCityState() + "\nYou have " + getEmpCount() + "employee(s)");
        return returnMe;
}Now, at first, when I initially tested my code, it was working just fine, printing out the right way
Point is -- now that Im practically finished with my program, and am going back and running it - calling the toString method gives me the address rather than the information . . . Can anyone help me with this issue??
Also, Im using JOptionPane to display everything, but -- at first, it worked fine, then (around the same time I started having the above problem) it stopped exiting the do-while loop:
while(go)
             int option = JOptionPane.showConfirmDialog(null, "Do you want to enter employee information?", "Welcome!", JOptionPane.YES_NO_OPTION);
                 if(option == JOptionPane.NO_OPTION)
                    go = false; //exit loop


ncjb wrote:
well, for the toString - I have to print out the info inside the array -- am I right in thinking that the only way to do this is to pass in the array ??If the array is part of the class then there is no need to pass it as a parameter. If it is being passed in from outside the class then I have to question your design. Why should class X being formatting data that is not a representation of itself?
and i have 2 other files that go with this program . . . I just want to know if there is a way to make sure that when the user presses the NO option, it will exit the loop -- the piece of code you see if apart of an entire method (not long) -- do you want me to include this??You read that link I provided REAL quick!

Using JOptionPane in a non-event dispatching thread

I am currently working on a screen that will need to called and displayed from a non-event dispatching thread. This dialog will also capture a user's selection and then use that information for later processing. Therefore, the dialog will need to halt the current thread until the user responds.
To start, I tried using the JOptionPane.showInputDialog() method and set the options to a couple of objects. JOptionPane worked as advertised. It placed the objects into a combobox and allowed the user to select one of them. However, it also gave me something unexpected. It actually paused the non-event handling thread until the user had made a selection. This was done without the JOptionPane code being wrapped in a SwingUtilities.invokeLater() or some other device that would force it to be launched from an Event Handling Thread.
Encouraged, I proceeded to use JOptionPane.showInputDialog() substituting the "message" Object with a fairly complex panel (JRadioButtons, JLists, JTextFields, etc.) that would display all of the variety of choices for the user. Now, when the screen pops up, it doesn't paint correctly (like what commonly occurs when try to perform a GUI update from a non-event dispatching thread) and the original thread continues without waiting for a user selection (which could be made if the screen painted correctly).
So, here come the questions:
1) Is what I am trying to do possible? Is it possible to create a fairly complex GUI panel and use it in one of the static JOptionPane.showXXXDialog() methods?
2) If I can't use JOptionPane for this, should I be able to use JDialog to perform the same type function?
3) If I can use JDialog or JFrame and get the threading done properly, how do I get the original thread to wait for the user to make a selection before proceeding?
I have been working with Java and Swing for about 7-8 years and have done some fairly complex GUIs, but for some reason, I am stumped here. Any help would be appreciated.
Thanks.

This seems wierd that it is functioning this way. Generally, this is what is supposed to happen. If you call a JOptionPane.show... from the Event Dispatch Thread, the JOptionPane will actually begin processing events that normally the Event Dispatch Thread would handle. It does this until the user selects on options.
If you call it from another thread, it uses the standard wait and notify.
It could be that you are using showInputDialog for this, try showMessageDialog and see if that works. I believe showInputDialog is generally used for a single JTextField and JLabel.

Trying to print a list using JOptionPane

I am very new to Java and programming, so please forgive me if this should be apparent. I wrote a program for school which was for ordering pizzas. I wrote it as a console program and after much frustration it finally worked. Now I am trying to change it to a GUI program using JOptionPane. I was hoping that since I already had the logic written and working, I could focus on the GUI aspect. I was wrong. I want to print a list of enums on a JOptionPane and cannot figure out how to do it My code in the console program was:
System.out.println("The available crust styles are: ");
     for(Pizza.Style style : Pizza.Style.values())
          System.out.println(style+" ");
So how can I iterate through the for loop to list all of the styles in the JOptionPane? Do I need to turn it into a method with a return and then cal the method like
JOptionPane.showMessageDialog(null, crustMethod()); ??

OP said:
... Now I am trying to change it to a GUI program using JOptionPane. I was hoping that since I already had the logic written and working, I could focus on the GUI aspect. I was wrong. ...I wouldn't use JOptionPane. You need JFrame and maybe, but I doubt it, a JDialog. OP, the GUI is more than likely to be nothing more than a form that allows users to set certain properties or fields in a Java class. For example let's say we have this class.
public class Point
public int x;
public int y;
}Then a GUI for this would be something like a JPanel with two (2) JLabels and two (2) JTextFields. Maybe something like so...
import java.awt.*;
import javax.swing.*;
public class PointGUI extends JPanel
public JLabel xLabel = new JLabel("Coordinate X:");
public JLabel yLabel = new JLabel("Coordinate Y:");
public JTextField xField = new JTextField(4);
public JTextField yField = new JTextField(4);
public PointGUI(){
    setLayout(new GridLayout(2, 2));
    add(xLabel);
    add(xField);
    add(yLabel);
    add(yField);
}Then to run the program...
import javax.swing.*;
public class Test
public static void main(String[] args){
    SwingUtitlities.invokeLater(new Runnable(){
      public void run(){
        PointGUI gui = new PointGUI();
        JFrame f = new JFrame("PointGUI");
        f.getContentPane().add(gui, "Center");
        f.pack();
        f.setDefaultCloseOperation(f.EXIT_ON_CLOSE);
        f.setVisible(true);
}... actually all the program does is display the GUI. But, can you see that the GUI's JLabels and JTextFields describe all the public properties of the Point class? Can you see that the entire GUI can be placed anywhere in a JFrame, or maybe even in a JDialog? From this point on, you can add other functions and features to your classes, GUI's and the main apps that run them.
A hint on your project, you may need to write a Pizza class that decribes all the things a single pizza can be - then come up with a GUI for that and an app that runs it.

Deleting a MS Access database table record using JOptionPane

hi!
just want some help here..
is there a way to delete a MS Access database record through using JOptionPane?? i've gone through some, probably alot of examples on SELECT, INSERT, UPDATE, DELETE statements but none came up to the stuff i need.
so far i've seen the DELETE statement like this and also this is a common DELETE statement..
statement.executeUpdate("DELETE FROM tableName WHERE fieldName01 = 'blablabla' AND fieldName02 = 'etcetcetc'");like INSERT, there's a coding somewhat like this:
String asd = JOptionPane.showInputDialog(null, "Enter blablabla stuff");
statement.executeUpdate("INSERT INTO whatEverTableName (tableFieldName) VALUES('"+asd.getText()+"')");so, is it possible using the same method for DELETE??
help and advices are appreciated in advanced..

Here's how I did it. Research does help, but sometimes looking at others code does too... You do have to have a dummy file that you made with access though. You can't just make a file file.mdb (it will be corrupt)
     public void createDatabase(String database) throws SQLException{
          try{
               // This file needs to have been created with MS Access
               File dbfile = new File(this.dataBaseDir + "dummy.mdb");
               // This is the new database file being made
               File newFile = new File(this.dataBaseDir + database + ".mdb");
               // Copy all bytes from dummy file to new DB file.
               FileInputStream instream = new FileInputStream(dbfile);
               FileOutputStream ostream = new FileOutputStream(newFile);
               int numBytes = instream.available();
               byte inBytes[] = new byte[numBytes];
               instream.read(inBytes, 0, numBytes);
               ostream.write(inBytes, 0, numBytes);
          catch(FileNotFoundException e) { e.printStackTrace();}
          catch(IOException e) { e.printStackTrace();}
          if(DEBUG) System.out.println("creating the " + database + " database");
     }

Comple errors using JOptionPane

I'm trying to write a Java program using JOptionPane dialog/display boxes that reads an integer and checks whether it is even using true/false statements. I also want the program must check if the number the user entered is between 1 and 1000.
I haven't found alot of help in the book I have and i've found some help in another forum but it doesn't seem to compile well, I get the following errors:
IntegerRead.java:39: cannot find symbol
symbol : method valueOf(java.lang.String)
location: class Integer
int number = Integer.valueOf(s);
^
Integer.java:13: cannot find symbol
symbol : class Scanner
location: class Integer
Scanner input = new Scanner( System.in );
^
Integer.java:13: cannot find symbol
symbol : class Scanner
location: class Integer
Scanner input = new Scanner( System.in );
Here is the code:
// Assignment 2.1: IntegerRead.java
// This program reads an integer, checks if it's even and is between 1 and 1000.
import javax.swing.JOptionPane; // program uses class JOptionPane
public class IntegerRead
public static boolean isNumber(String args)
if(args.length() > 3)
throw new IllegalArgumentException("Invalid argument");
else
boolean isNumber = false;
for(int i = 0; i < args.length(); i++)
char c = args.charAt(i);
if(Character.isDigit(c))
isNumber = true;
else
isNumber = false;
return isNumber;
public static boolean isEven(int aNumber)
int a = aNumber & 1;
return (a == 0);
public static void main(String args[])
String s = JOptionPane.showInputDialog("Please enter number between 0 to 999");
System.out.println("Is Number " + isNumber(s));
if(isNumber(s))
int number = Integer.valueOf(s);
System.out.println("Number " + number + "is Even " + isEven(number));
for(int i = 0; i < 999; i++)
System.out.println(i + " is " + isEven(i));
I know i'm missing very simple. I'm new and have tried to build upon what I have so far, but I can't figure it out.
Thanks....

You have a class named Integer somewhere on your class path. Get rid of it or rename it. If you've already renamed your Integer.java file, you still need to delete the Integer.class file. You should never create your own class that has the same name as a class in the standard java.lang package.

Using JOptionPane.showInputDialog to return an integer

I am currently using JOptionPane to return a string from the Object array i made with all possible choices.
     private static boolean determineService(){
          JLabel label;
          label=new JLabel("Please select which Service Model to use.",JLabel.CENTER);
          Object[] possibilities = {"AddressCleanse", "VIN", "PostalCode"};
          serviceModel = (String)JOptionPane.showInputDialog(
                              null,
                              label,
                              "Select Service",
                              JOptionPane.PLAIN_MESSAGE,null,
                              possibilities,
                              "AddressCleanse");
//          If a string was returned, say so.
          if ((serviceModel != null) && (serviceModel.length() > 0)) {
              System.out.println("You've selected " + serviceModel + "!");
              setVariables();
              return true;
          }else{
//               If you're here, the return value was null/empty.
               System.out.println("Null or Bad service selected!\n Exiting program.");
               return false;
          }I would like to instead return the response as an integr so I can then use a switch, rather than recursive if, else if logic.
Apparently java doesnt allow switches to use strings (like PHP does)
any ideas?

Just a question more than an answer: would using a hashmap ever work here? where the key is a string and the value is an (???) object that implements an interface that would allow you to call an appropriate method? Perhaps one could use the keySet() and toArray to build the Object array for the JOptionPane. I thought I read something about this somewhere, but am not sure....

Help using JOptionPane

please tell me how can i do following:
I want to add strings using JOptionPane.showInputDialog( ) method. in an ArrayList() of strings only.
I want to show input dialog box to user continously till user presses "enter" from keyboard.
please tell me the way to stop the loop when user presses "Enter" from keyboard.
//what i have done:
//created new ArrayList()
myStrings = new ArrayList();
while(1)
String theString = JOptionPane.showInputDialog("Enter string ");
myStrings.add(theString);
}

I want to show input dialog box to user continously
till user presses "enter" from keyboard.
please tell me the way to stop the loop when user
presses "Enter" from keyboard.You probably want to end the loop when the user clicks the cancel button on the dialog. Clicking the enter button invokes the button that has focus.

Using jOptionPane

I am using a jFileChooser like so...
fileChooser.showSaveDialog(jPanel1);
File file = new File(fileChooser.getCurrentDirectory()+"/"+fileChooser.getName(fileChooser.getSelectedFile()) + ".jpg");
filename = file.getPath();After this, the string filename is assigned to the pathname and file I want to save as. What I want is to now check if that file already exists, and using a JOptionPane, prompt a Yes or No do you want to overwrite? If yes it writes the file, if no go back and reshow the jFileChooser saveDialog and allow to re-enter a filename.
I also have this code...
if (new File(filename).exists()) {
        //show my JOptionPane confirm dialog here
        //ask yes or no to overwrite
        //if yes simply write the file
        //if no go back to my showSaveDialog up top
        }I have seen sample code and when I try it doesnt work. Could someone please tell me how I can do this?

1.
You should check the return value of the showSaveDialog. The return value will be JFileChooser.APPROVE_OPTION if the user pressed the Save button, and JFileChooser.CANCEL_OPTION if Cancel was pressed.
2.
If the return value is APPROVE_OPTION you can get the selected file immediately by calling getSelectedFile() on your filechooser. What you are doing now is very unnecessary, and I even think it might be wrong since the extension will appear twice (I could be wrong about this).
3.
You don't have to create a new File when you do the exists() check, just use the File returned to you by the file chooser
4.
When you post a problem, don't just say "it doesn't work". Explain exactly what it is that doesn't work, and how the problem manifests itself.
Steps 1-3 might look something like this:
int retVal = fileChooser.showSaveDialog(jPanel1);
if( retVal == JFileChooser.APPROVE_OPTION ) {
    File file = fileChooser.getSelectedFile();
    if( file.exists() ) {
        // Display the JOptionPane
else if( retVal == JFileChooser.CANCEL_OPTION ) {
    // The user pressed Cancel in the filechooser. Take appropriate action.
else if( retVal == JFileChooser.ERROR_OPTION ) {
    // An error occurred or the dialopg was dismissed. Take appropriate action.
}

Using JoptionPane icon in other dialogs

I was originally using a ProgressMonitor. but this wasn't flexible enough so i created my own subclass of JDialog which contained a JProgressBar.
This work fine but I want it to display the Information Icon that you get with ProgressMonitor and some JoptionPanes. How can I do this without subclassing JOptionPane.

I think....
Icon icon = UIManager.getDefaults().getIcon(key);
where key is one of...
OptionPane.errorIcon
OptionPane.informationIcon
OptionPane.questionIcon
OptionPane.warningIcon

Have "OK" button selected when using JOptionPane.showMessageDialog

When using the following instruction, I would like that user only hit enter instead of pointing the cursor on the "OK" button and then click.
JOptionPane.showMessageDialog( null, jta_output , "Solution",
JOptionPane.INFORMATION_MESSAGE );
Is there a way to "preselect" the "OK" button so that user can only hit the enter key?
Thanks

Thanks for your answer.
Nevertheless I don't see how to implement this method.
1. How can I link the "OK" button, resulting from the run of "JOptionPane.showMessageDialog( null, jta_output , "Solution", JOptionPane.INFORMATION_MESSAGE );" instruction, and the method "setInitialSelectionValue"?
2. What object and value must be specified to refer to the "OK" button, when using method "setInitialSelectionValue"?
Regards

Re: Using JOptionPane for Input and Output

You're going to get in big trouble with things like this: "if (memtype = P)"
Remember that '=' is for assignment, '==' is for comparison. Furthermore, you shouldn't use '==' for comparing Strings; you should use the String's equals() method instead.

Thank you for your reply and for the tip on using the ==,
I have seen this used, but the language you used to explain this is still a little too technical for me and I am not too sure what you mean when you said: "you should use the String's equals() method instead. "
what would the format of this look like?
