UITypeEditor 클래스
정의
값 편집기를 디자인하는 데 사용할 수 있는 기본 클래스를 제공합니다. 값 편집기는 지원되는 데이터 형식 개체의 값을 나타내고 편집할 수 있는 사용자 인터페이스를 제공합니다.Provides a base class that can be used to design value editors that can provide a user interface (UI) for representing and editing the values of objects of the supported data types.

예제
다음 코드 예제에서는를 UITypeEditor 사용 하 여 EditorAttribute 속성 창에서 디자인 모드의 각도 선택 인터페이스를 제공 하는 정수, double 또는 float 속성과 연결할 수 있음을 보여 줍니다.The following code example demonstrates that a UITypeEditor can be associated with an integer, double, or float property using an EditorAttribute to provide an angle selection interface from the Properties window in design mode. 이 예제에서는 인터페이스를 사용 하 여 IWindowsFormsEditorService 속성 창 디자인 모드의 드롭다운 컨트롤을 표시 합니다.This example uses the IWindowsFormsEditorService interface to display a drop-down control in the Properties window in design mode. Visual Studio의 도구 메뉴에서 도구 상자 사용자 지정 명령을 사용 하 여 코드를 컴파일하고 어셈블리를 도구 상자에 추가 합니다.Compile the code and add the assembly to the Toolbox using the Customize Toolbox command on the Tools menu of Visual Studio. 의 인스턴스를 만들고 AngleTestControl 속성 창의 각도 속성 옆에 있는 드롭다운 단추를 클릭 하 여 편집기를 사용 하 여 속성을 구성 합니다.Create an instance of the AngleTestControl and click the drop-down button next to the Angle property in the Properties window to configure the property using the editor.

설명
UITypeEditor클래스는 파생 시킬 수 있는 기본 클래스를 제공 하 고, 디자인 타임 환경에 대 한 사용자 지정 형식 편집기를 구현 하기 위해를 확장할 수 있습니다.The UITypeEditor class provides a base class that you can derive from and extend to implement a custom type editor for the design-time environment. 일반적으로 사용자 지정 형식 편집기는 컨트롤과 상호 작용 PropertyGrid 합니다.Typically, your custom type editor interacts with the PropertyGrid control.
사용자 지정 형식 편집기는 텍스트 상자 값 편집기에서 특정 형식의 값을 효과적으로 선택 하는 데 충분 하지 않은 경우에 유용 합니다.Custom type editors are useful in situations where a text-box value editor is insufficient to effectively select the values of certain types.
사용자 지정 디자인 타임 UI 형식 편집기를 구현 하려면 다음 단계를 수행 해야 합니다.To implement a custom design-time UI type editor, you must perform the following steps:
UITypeEditor에서 파생된 클래스를 정의합니다.Define a class that derives from UITypeEditor.
메서드를 재정의 EditValue 하 여 사용자 인터페이스, 사용자 입력 처리 및 값 할당을 처리 합니다.Override the EditValue method to handle the user interface, user input processing, and value assignment.
GetEditStyle편집기에서 사용할 편집기 스타일의 유형을 속성 창에 알리기 위해 메서드를 재정의 합니다.Override the GetEditStyle method to inform the Properties window of the type of editor style that the editor will use.
다음 단계를 수행 하 여 속성 창에서 값 표시를 그리기 위한 추가 지원을 추가할 수 있습니다.You can add additional support for painting a value's representation in the Properties window by performing the following steps:
메서드를 재정의 GetPaintValueSupported 하 여 편집기에서 값 표현의 표시를 지원함을 나타냅니다.Override the GetPaintValueSupported method to indicate that the editor supports displaying the value's representation.
PaintValue값 표현의 표시를 구현 하려면 메서드를 재정의 합니다.Override the PaintValue method to implement the display of the value's representation.
UITypeEditor편집기에서 초기화 동작을 포함 해야 하는 경우 생성자 메서드를 재정의 합니다.Override the UITypeEditor constructor method if the editor should have initialization behavior.
참고
UITypeEditor클래스에서 RTL (오른쪽에서 왼쪽) 레이아웃을 지원 하지 않습니다.The UITypeEditor class does not support right-to-left (RTL) layouts.
디자인 타임 지원 기능을 개선 하는 방법에 대 한 자세한 내용은 디자인 타임 지원 확장을 참조 하세요.For more information about enhancing design-time support, see Extending Design-Time Support. 구현에 대 한 자세한 내용은 UITypeEditor 사용자 인터페이스 형식 편집기 개요를 참조 하세요.For more information on implementing a UITypeEditor, see User Interface Type Editors Overview.
