How to make the length of Message Dialog follows the length of text

Question

Hi all.
I am making a Message Dialog From JOptionPane because i do not want to use some static methods of JOptionPane (JOptionPane.Show ...)
My source codes following :
public static void showMessageDialog(String message) {
          JOptionPane optionPane = new JOptionPane();
          JDialog dialog = optionPane.createDialog(null, "Message");
          optionPane.setMessage(message);
          optionPane.setMessageType(JOptionPane.INFORMATION_MESSAGE);
          JButton btnOk = new JButton("OK");
          optionPane.setOptions(new Object[] { btnOk });
          dialog.setVisible(true);
}It runs well but having a problem. When message is a long text --> JDialog can not show all text, dialog's length does not resize automatically following message's length.
Have a the way to make it ? How to solve ?
Thanks in advance !

Answer 1

Add a dialog.pack() call. See SSCCE below.
i do not want to use some static methods of JOptionPane (JOptionPane.Show ...)Why? In this case the built-in static method handles the size as expected.
public class TestJOptionPaneSizeAdaptsToMessageLength {
   public static void main(String... args) {
       String message = "This is a very long message, I say long but really it is a very very long one, and when I say long I do mean it!!! ";
       message += message;
       message += message;
       message += message;
       showMessageDialog(message);
//       showMessageDialogUsingStaticJOptionPaneMethod(message);
   public static void showMessageDialog(String message) {
        JOptionPane optionPane = new JOptionPane();
        JDialog dialog = optionPane.createDialog(null, "Message");
        optionPane.setMessage(message);
        optionPane.setMessageType(JOptionPane.INFORMATION_MESSAGE);
        JButton btnOk = new JButton("OK");
        optionPane.setOptions(new Object[] { btnOk });
        dialog.pack();
        dialog.setVisible(true);
   public static void showMessageDialogUsingStaticJOptionPaneMethod(String message) {
        JOptionPane.showMessageDialog(null, message);

I have to admit, I am a zealous fan of the built-in JOptionPane.showXxx methods :o)
