Changing the Background of a button after it is clicked (i.e. after Action performed)

I am trying to change the background of a JButton after it is clicked. Currently my buttons are located in a GridLayout (3x3) and look like this:

tiles.add(new JButton(new AbstractAction("") {
    @Override
    public void actionPerformed(ActionEvent e) {
        this.setIcon("foo.png");
    }
}));

This does not work. How do I manipulate the background of the image from within the actionperformed?

Solution

  • A JToggleButton might be ideal for this, as shown on Swing JToolbarButton pressing

    Note that you would need to add some code to ensure a button was only clickable once.

    Alternately you might use a standard JButton and call AbstractButton.setDisabledIcon(Icon). Disable the button when clicked, and it will flip to the alternate icon.
