설명
구현자 참고 사항 클래스에서 컨트롤 컬렉션의 부모로 지정할 이 인터페이스를 구현합니다. 이 인터페이스의 멤버를 사용하면 자식 컨트롤을 활성화하거나 현재 활성 상태인 컨트롤을 확인할 수 있습니다. 클래스에서 구현되는 경우 ActivateControl은 Control을 매개 변수로 사용하며 지정된 컨트롤을 활성화합니다. ActiveControl 속성은 활성 컨트롤을 활성화하거나 검색합니다. 대부분의 일반적인 시나리오에서는 사용자가 직접 이 인터페이스를 구현할 필요가 없습니다. 예를 들어, Windows 컨트롤 라이브러리 프로젝트를 만들면 Visual Studio에서 초기 클래스를 생성합니다. 이 클래스는 UserControl 클래스에서 상속되며 사용자 대신 UserControl에서 IContainerControl을 구현합니다.
예제
다음 예제에서는 ScrollableControl 클래스에서 상속하여 IContainerControl 인터페이스를 구현합니다. ActiveControl 속성 및 ActivateControl 메서드에 구현이 추가됩니다.
