Can somebody explain to me the answer: What is true of the listeners?
A. the return type is boolean B. most components allow multiple listeners to be added. C. a copy of the original event is passed into a listener method I said B, and C, the mock exam said B only. I thought all listeners had methods which had a handle on an "event" object. Can somebody explain to me what my confusion is?
hi Wilson I think about twenty miniutes and find out a possible solution. C. a copy of the original event is passed into a listener method The answer does not say something before you need to do. It may be tricky or I misunderstand it Original event/event source should be registered first,than it can be passed into a listener method. It may be a suitable answer
