    public class RepeatButton

extends JButton
implements ActionListener, MouseListener

`RepeatButton` is a `JButton` which contains a timer for firing events while the button is held down. There is a default initial delay of 300ms before the first event is fired and a 60ms delay between subsequent events. When the user holds the button down and moves the mouse out from over the button, the timer stops, but if the user moves the mouse back over the button without having released the mouse button, the timer starts up again at the same delay rate. If the enabled state is changed while the timer is active, it will be stopped. NOTE: The normal button behavior is that the action event is fired after the button is released. It may be important to konw then that this is still the case. So in effect, listeners will get 1 more event then what the internal timer fires. It's not a "bug", per se, just something to be aware of. There seems to be no way to suppress the final event from firing anyway, except to process all ActionListeners internally. But realistically, it probably doesn't matter.
