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.

/Note: Please Don’t Suggest me the way of JOptionPane.ShowOptionDialog(*****);** for this issue because i know that way but i need above mentioned way of doing and setting actions for “OK” and “CANCEL” buttons.*/

This works for me:

...
JOptionPane pane = new JOptionPane(message,  JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
JDialog getTopicDialog =  pane.createDialog(null, "New Topic");
getTopicDialog.setVisible(true);
if(null == pane.getValue()) {
    System.out.println("User closed dialog");
}
else {
    switch(((Integer)pane.getValue()).intValue()) {
    case JOptionPane.OK_OPTION:
        System.out.println("User selected OK");
        break;
    case JOptionPane.CANCEL_OPTION:
        System.out.println("User selected Cancel");
        break;
    default:
        System.out.println("User selected " + pane.getValue());
    }
}
