Custom JDialog - Find out if OK was presed

I have a custom JDialog that I made in order to solve some local problems (RTL etc') until now, it only had an "ok" option, I have to modify it now to also have a cancel button. I did that. the only problem now is that I don't know how to get the input from it, was OK pressed or Cancel ?

please help.

this is my code:

public MyDialog(String title,boolean withCancelButton) {

String message = "<html><b><font color=\"#8F0000\" size=\"7\" face=\"Ariel\">" + title + "</font></p></html>";

JOptionPane pane = new JOptionPane(message, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
pane.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);        

JDialog dialog = pane.createDialog(null, title);

dialog.setVisible(true);
dialog.dispose();

if (pane.getOptionType() == 1)
    okWasPressed = true;
else
    okWasPressed = false;

}

the thing is that pane.getOptionType() always return "2", so its probably the options count or something.

how can I get to the actual selection ?

thanks, Dave.

The easiest option is to use the standard functionality, like this:

int opt = JOptionPane.showOptionDialog(jf, "Do you really want to?", "Confirm",
        JOptionPane.OK_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, null, null);
if(opt == JOptionPane.OK_OPTION) {
    System.out.println("Ok then!");
} else {
    System.out.println("Didn't think so.");
}

If you really want to use your own dialog, as in the example, you should use getValue() to check what was pressed:

JOptionPane optionPane = new JOptionPane("Do you really want to?",
        JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
JDialog dialog = optionPane.createDialog(jf, "Confirm");

dialog.setVisible(true);
dialog.dispose();

int opt = (int) optionPane.getValue();
if(opt == JOptionPane.OK_OPTION) {
    System.out.println("Ok then!");
} else {
    System.out.println("Didn't think so.");
}

Ask described in the JavaDocs...

 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;

You should be able to use JOptionPane#getValue()

However, unless you some massively pressing reason to do so, you should use one of the static factory methods. See How to Make Dialogs for more details

Usually it can be done like this:

int response = JOptionPane.showConfirmDialog(parent, "message", "title", JOptionPane.OK_CANCEL_OPTION);
System.out.println(response);
