JOptionPane.createDialog and OK_CANCEL_OPTION

Question

I have a custom dialog box that collects two strings from the user. I use OK_CANCEL_OPTION for the option type when creating the dialog. Evertyhings works except when a user clicks cancel or closes the dialog it has the same effect has clicking the OK button.

How can i handle the cancel and close events?

Heres the code I'm talking about:

JTextField topicTitle = new JTextField();
JTextField topicDesc = new JTextField();
Object[] message = {"Title: ", topicTitle, "Description: ", topicDesc};

JOptionPane pane = new JOptionPane(message,  JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
JDialog getTopicDialog =  pane.createDialog(null, "New Topic");
getTopicDialog.setVisible(true);

// Do something here when OK is pressed but just dispose when cancel is pressed.

I think a better option for you would be to use the following code

    JTextField topicTitle = new JTextField();
    JTextField topicDesc = new JTextField();
    Object[] message = {"Title: ", topicTitle, "Description: ", topicDesc};


    Object[] options = { "Yes", "No" };
    int n = JOptionPane.showOptionDialog(new JFrame(),
            message, "",
            JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null,
            options, options[1]);
    if(n == JOptionPane.OK_OPTION){ // Afirmative
        //.... 
    }
    if(n == JOptionPane.NO_OPTION){ // negative
        //....
    }
    if(n == JOptionPane.CLOSED_OPTION){ // closed the dialog
        //....
    }

by using the showOptionDialog method, you are getting an result based on what the user does, so you don't need to do anything else except for interpret that result
