Class ExtBasicArrowButtonHandler

    java.lang.Object
      javax.swing.AbstractAction
          com.jgoodies.looks.common.ExtBasicArrowButtonHandler

All Implemented Interfaces:
  ActionListener, FocusListener, MouseListener, Serializable, Cloneable, EventListener, Action

    public final class ExtBasicArrowButtonHandler

extends AbstractAction
implements MouseListener, FocusListener

A handler for spinner arrow button mouse and action events. When a left mouse pressed event occurs we look up the (enabled) spinner that's the source of the event and start the autorepeat timer. The timer fires action events until any button is released at which point the timer is stopped and the reference to the spinner cleared. The timer doesn't start until after a 300ms delay, so often the source of the initial (and final) action event is just the button logic for mouse released - which means that we're relying on the fact that our mouse listener runs after the buttons mouse listener.

Note that one instance of this handler is shared by all slider previous arrow buttons and likewise for all of the next buttons, so it doesn't have any state that persists beyond the limits of a single button pressed/released gesture.
