Buttons behave differently if they are clicked directly with a mouse or through
the setDefaultButton feature. In one instance, "button pressed" is painted.
In the other, it is not. It is disorienting to a user not see the "button
pressed" painted. This is true for Metal , Motif and Windows Look & Feel.


To test - run this program. Click on the button and then hit the enter key and
see the difference.

import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.*;

public class DefaultButton extends JFrame {

  private int count = 0;
  private JButton button = new JButton("Hit ... Me");
  private JLabel label = new JLabel("Hit Count = " + count);
  private JPanel contentPane = new JPanel();

  public DefaultButton () {
    super("Button Frame");

    setContentPane(contentPane);
    contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.Y_AXIS));
    contentPane.setBorder(BorderFactory.createEmptyBorder(20,20,20,20));
    contentPane.add(button);
    contentPane.add(label);

    this.getRootPane().setDefaultButton(button);
    button.setPreferredSize(new Dimension(100, 35));

    button.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        count++;
        label.setText("Hit Count = " + count);
      }
    });
    this.pack();
    this.setVisible(true);
    this.setLocation(200,200);
