Popup window event

[venkatesh pendharkar]

HI all,
I am creating a Java application in which i want to open a popup which displays some message.Currentl i am using JOptionPane.showMessageDialog(this,"msg"); method which shows dialog with OK button. But I dont understand how to fire an event in the OK button of this window. Is there any method by which i will be able to execure some code when OK button is clicked. I tried using windowClose event but it doesnt work .
Someone please help me in this.

package demo;
 
import javax.swing.JOptionPane;
 
/* execure some code when OK button is clicked.
 * Many possibel approaches skipped awaiting further
 * suggestions and questions from original poster.
 */
 
public class ExecureSomeCode
{
    JOptionPane pane = new JOptionPane(arguments);
    // There are different return types for JOption Pane
    // This sample scoped to integers
    int message = pane.showInternalConfirmDialog;
    case ( YES_OPTION )     : some action(0); break;//
    case ( NO_OPTION )      : some action(1); break;//
    case ( CANCEL_OPTION )  : some action(2); break;//
    case ( OK_OPTION )      : some action(3); break;//
    case ( CLOSED_OPTION  ) : some action(4); break;//
}

Alternately:

     JOptionPane pane = new JOptionPane(arguments);
     pane.set.Xxxx(...); // Configure
     JDialog dialog = pane.createDialog(parentComponent, title);
     dialog.show();
     Object selectedValue = pane.getValue();
     if(selectedValue == null)
       return CLOSED_OPTION;
     //If there is not an array of option buttons:
     if(options == null) {
       if(selectedValue instanceof Integer)
          return ((Integer)selectedValue).intValue();
       return CLOSED_OPTION;
     }
     //If there is an array of option buttons:
     for(int counter = 0, maxCounter = options.length;
        counter < maxCounter; counter++) {
        if(options[counter].equals(selectedValue))
        return counter;
     }
     return CLOSED_OPTION;
