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?


However, what about just using

Works for me:

package fubar;

import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class ButtonIconTest {

    public static void main(String[] args) throws Exception

        SwingUtilities.invokeLater( new Runnable() {

            public void run()
        } );

    private static void createAndShowGui()
        ImageIcon dog = null;
        ImageIcon pig = null;
            dog = new ImageIcon(
URL("" +

"examples/components/SplitPaneDemoProject/src/components/" +
            pig = new ImageIcon(
                    + "images/Pig.gif"));
        } catch (MalformedURLException ex)

                    "Error loading images:", ex);
        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.setLocationRelativeTo( null );
        frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        frame.setVisible( true );


I already use pressed icon.
So, I have redIcon and pressedRedIcon and when I push the button I want
it to change to greenIcon and greenPressedIcon as a toggle on an if-else

repaint() doesn't seem to do anything
