설명

UITypeEditor 클래스에서 제공하는 기본 클래스를 사용하여 파생 클래스를 만들고, 기본 클래스를 확장하여 디자인 타임 환경에 맞는 사용자 지정 형식 편집기를 구현할 수 있습니다. 사용자 지정 형식 편집기는 텍스트 상자 값 편집기에서 특정 형식의 값을 효율적으로 선택할 수 없는 경우에 유용합니다.

사용자 지정 디자인 타임 UI 형식 편집기를 구현하려면 다음 단계를 수행해야 합니다.

  • UITypeEditor에서 파생되는 클래스를 정의합니다.

  • EditValue 메서드를 재정의하여 사용자 인터페이스, 사용자 입력 처리 및 값 할당을 처리합니다.

  • GetEditStyle 메서드를 재정의하여 해당 편집기에서 사용할 편집기 스타일 형식을 속성 창에 알립니다.

다음 단계를 수행하여 속성 창에서 값 표현 칠하기를 위한 추가 지원을 추가할 수 있습니다.

  • GetPaintValueSupported 메서드를 재정의하여 해당 편집기에서 값 표현의 표시를 지원할 수 있음을 나타냅니다.

  • PaintValue 메서드를 재정의하여 값 표현의 표시 기능을 구현합니다.

  • 편집기에 초기화 동작이 포함되어야 하는 경우에는 UITypeEditor 생성자 메서드를 재정의합니다.

참고

UITypeEditor 클래스는 RTL(오른쪽-왼쪽) 레이아웃을 지원하지 않습니다.

디자인 타임 지원 향상에 대한 자세한 내용은 디자인 타임 지원 확장을 참조하십시오. UITypeEditor 구현에 대한 자세한 내용은 사용자 인터페이스 형식 편집기 개요를 참조하십시오.

예제

다음 코드 예제에서는 UITypeEditorEditorAttribute를 사용하여 integer, double 또는 float 속성과 연결됨으로써 디자인 모드의 속성 창에서 각도 선택 인터페이스를 제공할 수 있음을 보여 줍니다. 이 예제에서는 IWindowsFormsEditorService 인터페이스를 사용하여 디자인 모드의 속성 창에서 드롭다운 컨트롤을 표시합니다. 코드를 컴파일하고 Visual Studio의 도구 메뉴에 있는 도구 상자 사용자 지정 명령을 사용하여 도구 상자에 어셈블리를 추가합니다. AngleTestControl의 인스턴스를 만들고 편집기를 사용하여 속성 창에서 각도 속성 옆의 드롭다운 단추를 클릭하여 속성을 구성합니다.
