설명

구성 요소 편집기를 전체 구성 요소를 편집할 사용 되 고 속성 페이지와 비슷한 사용자 인터페이스 구현에 사용할 수 있습니다.A component editor is used to edit a component as a whole and can be used to implement a user interface similar to that of the property pages. 구성 요소 편집기를 사용 하 여 구성 요소를 사용 하 여 연결 하는 EditorAttribute 특성입니다.You associate a component editor with a component by using the EditorAttribute attribute.

상속자 참고

이 클래스에서 상속 하는 경우 재정의 해야 합니다는 EditComponent(Object) 메서드.When you inherit from this class, you must override the EditComponent(Object) method.

생성자

ComponentEditor() ComponentEditor() ComponentEditor() ComponentEditor()

ComponentEditor 클래스의 새 인스턴스를 초기화합니다.Initializes a new instance of the ComponentEditor class.

메서드
