How to remove question mark in a JOptionPane?

Question

How can I get rid of any marks at the left top corner of a JOptionPane?

int result = JOptionPane.showConfirmDialog(null, myPanel, 
                   "Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);

This works fine, but I want to remove the nasty ? at the left top corner.

Answer 1

Use the PLAIN_MESSAGE message type

JOptionPane.showConfirmDialog(null, "Help",
    "Please Enter X and Y Values", 
    JOptionPane.OK_CANCEL_OPTION, 
    JOptionPane.PLAIN_MESSAGE);
