설명

이벤트 처리기는 이 이벤트에 대한 데이터가 들어 있는 StrokesEventArgs 형식의 인수를 받습니다.

StrokesEventHandler 대리자를 만드는 경우 이벤트를 처리하는 메서드를 식별합니다. 이벤트를 이벤트 처리기와 연결하려면 대리자의 인스턴스를 해당 이벤트에 추가합니다. 대리자를 제거하지 않는 경우 이벤트가 발생할 때마다 이벤트 처리기가 호출됩니다.

예제

이 예제에서 StrokesRemoved 이벤트 처리기는 제거된 Stroke 개체를 사용자 지정 Strokes 컬렉션에 저장합니다.

' on any Strokes collection to which an event handler has been attached before 
' the collection goes out of scope.
