예제

다음 코드 예제에서는 OnMouseHover 파생 클래스의 및 메서드를 재정의 하는 방법을 보여 줍니다 OnMouseMove .The following code example demonstrates how to override the OnMouseHover and OnMouseMove methods in a derived class. 예제를 실행, 새 폼에 다음 코드를 붙여 붙여넣습니다이 클래스를 같은 파일 형식을 만듭니다.To run the example, paste the following code in a new form and paste this class, forming the same file, after the form. 형식의 단추를 FunButton 폼에 추가 합니다.Add a button of type FunButton to the form.

// To use this example create a new form and paste this class 
// forming the same file, after the form class in the same file.  
// Add a button of type FunButton to the form.

설명

이벤트가 발생하면 대리자를 통해 이벤트 처리기가 호출됩니다.Raising an event invokes the event handler through a delegate. 자세한 내용은 이벤트 처리 및 발생합니다.For more information, see Handling and Raising Events.

또한 OnMouseMove 메서드를 사용하면 파생 클래스가 대리자를 연결하지 않고도 이벤트를 처리할 수 있습니다.The OnMouseMove method also allows derived classes to handle the event without attaching a delegate. 이는 파생 클래스에서 이벤트를 처리하는 기본 방법입니다.This is the preferred technique for handling the event in a derived class.

상속자 참고

파생 클래스에서 OnMouseMove(MouseEventArgs)를 재정의하는 경우 등록된 대리자가 이벤트를 받도록 기본 클래스의 OnMouseMove(MouseEventArgs) 메서드를 호출해야 합니다.When overriding OnMouseMove(MouseEventArgs) in a derived class, be sure to call the base class's OnMouseMove(MouseEventArgs) method so that registered delegates receive the event.
