Hey,
I was just wondering what is up with this. I got the framed class must implement inherited abstract class ItemListener.itemStateChange(ItemEvent); error when I tried to implement ItemListner, and it highlighted framed. I tryed my own version as this: GuideBook . I don't know what the issue is. I tried to google this issue, as well as cross reference the other example, and nothing. Could anyone shed some light on this? Thanks!
