I want to be able to change the icon of a button when it is pressed.
So, for example, I have a red button. I press it and it changes to a
green button. I have set the new icon in the button action code, but
cannot find a way to redraw it so that it changes instantly. What
method do I use?
repaint()?
However, what about just using
http://java.sun.com/javase/6/docs/api/javax/swing/AbstractButton.html#setPressedIcon(javax.swing.Icon)
Works for me:

JFrame frame = new JFrame( "Example Images" );
JPanel panel = new JPanel();
panel.add( new JLabel( dog ) );
panel.add( new JLabel( pig ) );
JButton button = new JButton( dog );
button.setPressedIcon( pig );
panel.add( button );
frame.add( panel );
frame.pack();
frame.setLocationRelativeTo( null );
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frame.setVisible( true );
}
}
