설명

IDesignerHost는 .NET Framework 폼 디자이너 아키텍처를 사용하여 디자이너 트랜잭션과 구성 요소 관리 지원을 제공하는 인터페이스입니다.

.NET Framework는 이 인터페이스를 구현하지 않습니다. 이 인터페이스는 디자이너를 지원하는 개발 도구에 의해 구현됩니다.

호출자 참고 사항 개발 환경에서 IDesignerHost를 구현하려면, 구성 요소가 디자인 모드에 활성화되어 있는 동안에 GetService를 호출하고 IDesignerHost의 형식을 전달하여 IDesignerHost 서비스 인터페이스를 요청합니다. IDesignerHost에서는 디자이너 상태와 관련된 다음 멤버를 제공합니다.

Loading 속성은 디자이너나 문서가 로드되고 있는지 여부를 나타냅니다.
Activated 이벤트는 디자이너가 표시되기 전에 활성화될 때 발생합니다.
Deactivated 이벤트는 디자이너가 비활성화될 때 발생합니다.
LoadComplete 이벤트는 문서가 로드된 후에 발생합니다.
Activate 메서드는 디자이너를 활성화합니다.

IDesignerHost에서는 구성 요소 관리와 관련된 다음 멤버를 제공합니다.

Container 속성은 디자이너 호스트에 대한 컨테이너를 나타냅니다.
RootComponent 속성은 루트 구성 요소에 대한 기본 클래스를 나타냅니다.
RootComponentClassName 속성은 루트 구성 요소의 클래스 이름을 나타냅니다.
CreateComponent 메서드는 지정된 형식의 구성 요소를 만듭니다.
DestroyComponent 메서드는 지정된 구성 요소를 소멸시킵니다.
GetDesigner 메서드는 지정된 구성 요소와 관련된 디자이너를 가져옵니다.
GetType 메서드는 지정된 이름 형식의 인스턴스를 가져옵니다.

IDesignerHost에서는 트랜잭션 관리와 관련된 다음 멤버를 제공합니다.

InTransaction 속성은 디자이너가 트랜잭션에 있는지 여부를 나타냅니다.
TransactionDescription 속성은 현재 트랜잭션 설명을 나타냅니다.
TransactionClosed 이벤트는 트랜잭션이 완료되었을 때 발생합니다.
TransactionClosing 이벤트는 트랜잭션이 완료되기 직전에 발생합니다.
TransactionOpened 이벤트는 트랜잭션이 시작되었을 때 발생합니다.
TransactionOpening 이벤트는 트랜잭션이 시작되기 직전에 발생합니다.
CreateTransaction 메서드는 새 트랜잭션을 만들어 반환합니다.

예제

다음 예제 코드에서는 디자이너나 사이트 정보를 포함하는 구성 요소에서 IDesignerHost 서비스 인터페이스를 얻는 방법을 보여 줍니다.

' Requests an IDesignerHost service from the design time environment using Component.Site.GetService()
Dim host As IDesignerHost = CType(Me.Component.Site.GetService(GetType(IDesignerHost)), IDesignerHost)

// Requests an IDesignerHost service from the design time environment using Component.Site.GetService()
IDesignerHost dh = (IDesignerHost) this.Component.Site.GetService(typeof(IDesignerHost));

// Requests an IDesignerHost service from the design time environment using Component.Site.GetService()
IDesignerHost^ dh = static_cast<IDesignerHost^>(this->Component->Site->GetService( IDesignerHost::typeid ));

// Requests an IDesignerHost service from the design time 
// environment using Component.Site.GetService()
IDesignerHost dh = (IDesignerHost)this.get_Component().get_Site().
    GetService(IDesignerHost.class.ToType());

다음 예제 코드에서는 IDesignerHost 인터페이스를 사용하여 프로젝트 구성 요소를 나열합니다.
