JButton in JDialog vs JOptionPane

Question

I have created two different JDialogs, one with JOptionPane and one in the old-fashioned way. My problem is that the buttons in the different JDialogs get different appearence (I'm usings javas Metal L&F). Take a look at this sample code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class TestFrame extends JFrame implements ActionListener {
   JDialog dialog1;
   JDialog dialog2;
   JButton button1;
   JButton button2;
   JButton dialogButton;
   public TestFrame() {
      button1 = new JButton("Open dialog 1");
      button1.addActionListener(this);
      button2 = new JButton("Open dialog 2");
      button2.addActionListener(this);
      getContentPane().add(button1, BorderLayout.NORTH);
      getContentPane().add(button2, BorderLayout.SOUTH);
      pack();
      setVisible(true);
   public static void main(String args[]) {
      new TestFrame();
   public void openDialog1() {
      JOptionPane vAbout = new JOptionPane("Just some text...", JOptionPane.INFORMATION_MESSAGE);
      dialog1 = vAbout.createDialog(this, "Dialog 1");
      dialog1.show();
   public void openDialog2() {
      dialog2 = new JDialog(this, "Dialog 2", true);
      GridBagLayout gbl = new GridBagLayout();
      GridBagConstraints gbc = new GridBagConstraints();
      dialog2.getContentPane().setLayout(gbl);
      JLabel text = new JLabel("Just some text...");
      dialogButton = new JButton("OK");
      dialogButton.addActionListener(this);
      dialog2.getContentPane().add(text, gbc);
      gbc.gridy = 1;
      dialog2.getContentPane().add(dialogButton, gbc);
      dialog2.pack();
      dialog2.setVisible(true);
   public void actionPerformed(ActionEvent e) {
      System.out.println(e.getSource());
      if (e.getSource() == button1)
         openDialog1();
      if (e.getSource() == button2)
         openDialog2();
      if (e.getSource() == dialogButton)
         dialog2.dispose();
   protected void processWindowEvent(WindowEvent e) {
      super.processWindowEvent(e);
      if(e.getID() == WindowEvent.WINDOW_CLOSING) {
         System.exit(0);
}How can I get my button in dialog2 to look the same as the button in dialog1?

To set the button to be default, you need some modification. Here's the basic frame work:
public class TestFrame() extends JFrame
   //Your constructor
   public TestFrame()
      //Do stuff in here
      myDialog mydialog = new myDialog(this);
      mydialog.show()
   public static void main(String[] args)
      //etc
   private void SomeOtherMethods()
       //Declare your JOptionPane
public class myDialog extends JDialog
   //Constructor
   public myDialog()
       //Add Components like usual
       getRootPane.setDefaultButton(DialogButton);
       getContentPane.add(Your_Panels);
    private void SomeOtherMethods()
}Basically, you're taking your JDialog and placing it in it's own class (which is better anyway, trust me). Then it will set the button as the default and make the border darker.
Let me know if you have anymore questions.
