AccessibleObject.Name AccessibleObject.Name AccessibleObject.Name AccessibleObject.Name Property

정의

개체 이름을 가져오거나 설정합니다.Gets or sets the object name.

public:
 virtual property System::String ^ Name { System::String ^ get(); void set(System::String ^ value); };
public virtual string Name { get; set; }
member this.Name : string with get, set
Public Overridable Property Name As String

속성 값

개체 이름이며 속성이 설정되어 있지 않으면 null입니다.The object name, or null if the property has not been set.

예외

컨트롤의 이름을 검색하거나 설정할 수 없는 경우The name of the control cannot be retrieved or set.

예제

다음 예제에서는 내게 필요한 옵션 인식 차트를 만드는 컨트롤을 사용 하는 AccessibleObjectControl.ControlAccessibleObject 액세스할 수 있는 정보를 노출 하는 클래스입니다.The following example demonstrates the creation of an accessibility-aware chart control, using the AccessibleObject and Control.ControlAccessibleObject classes to expose accessible information. 컨트롤은 범례를 따라 두 곡선을 그립니다.The control plots two curves along with a legend. 합니다 ChartControlAccessibleObject 클래스에서 파생 되는 ControlAccessibleObject에 사용 되는 CreateAccessibilityInstance 차트 컨트롤에 대 한 사용자 지정 액세스할 수 있는 정보를 제공 하는 방법입니다.The ChartControlAccessibleObject class, which derives from ControlAccessibleObject, is used in the CreateAccessibilityInstance method to provide custom accessible information for the chart control. 차트 범례 실제 아니므로 Control -컨트롤을 따르지만 그려지며 차트 컨트롤에 의해 되지 않은 기본 제공 정보를 액세스할 수 있습니다.Since the chart legend is not an actual Control -based control, but instead is drawn by the chart control, it does not have any built-in accessible information. 이 인해 합니다 ChartControlAccessibleObject 재정의 클래스를 GetChild 반환 하는 방법은 CurveLegendAccessibleObject 범례의 각 부분에 액세스할 수 있는 정보를 나타내는입니다.Because of this, the ChartControlAccessibleObject class overrides the GetChild method to return the CurveLegendAccessibleObject that represents accessible information for each part of the legend. 인식 액세스할 수 있는 응용 프로그램에서이 컨트롤을 사용 하는 경우 컨트롤이 필요한 액세스할 수 있는 정보를 제공할 수 있습니다.When an accessible-aware application uses this control, the control can provide the necessary accessible information.

설명

Name 속성은 식별, 검색 또는 사용자에 대 한 개체를 발표를 위해 클라이언트에서 사용 하는 문자열입니다.The Name property is a string used by clients to identify, find, or announce an object for the user. 자식 개체의 이름에 액세스 하려면 먼저 불러와야 GetChild 자식의 이름을 검색 하는 인덱스를 사용 하 여 합니다.To access the name of a child object, you must first call GetChild with the index of the child whose name you are retrieving.

상속자 참고

모든 개체는이 속성을 지원 해야 합니다.All objects should support this property. 개체의 이름은 사용자 개체의 의미 나 용도 이해할 수 있도록 직관적 이어야 합니다.An object's name should be intuitive so that users understand the object's meaning or purpose. 또한 했는지를 Name 속성은 부모에서 모든 형제 개체에 대해 고유 합니다.Also, ensure that the Name property is unique relative to any sibling objects in the parent. 일부 사용자에 게 특히 어려운 문제를 표시 하는 테이블 내에서 탐색 합니다.Navigation within tables presents especially difficult problems for some users. 따라서 server 개발자 해야 테이블 셀 이름을 최대한으로 설명 합니다.Therefore, server developers should make table cell names as descriptive as possible. 예를 들어 셀 이름을 "A1."와 같은 차지 하는 열과 행의 이름을 결합 하 여 만들 수 있습니다.For example, you might create a cell name by combining the names of the row and column it occupies, such as "A1." 그러나 편이 일반적으로 "Karin, 2 월."와 같은 보다 알기 쉬운 이름으로 사용 하려면However, it is generally better to use more descriptive names, such as "Karin, February." 아이콘, 메뉴, 확인란, 콤보 상자, 다른 컨트롤 등의 많은 개체에는 사용자에 게 표시 되는 레이블이 있습니다.Many objects, such as icons, menus, check boxes, combo boxes, and other controls, have labels that are displayed to users. 개체에 사용할 사용자에 게 표시 되는 모든 레이블을 Name 속성입니다.Any label displayed to users should be used for the object's Name property. 자세한 내용은 참조는 Name 속성입니다.For more information, see the Name Property.

에 대 한 메뉴 또는 단추 텍스트를 사용 하는 경우는 Name 속성인 경우 앰퍼샌드가 제거 (&) 키보드 선택 키를 표시 하는 합니다.If you are using menu or button text for the Name property, strip out the ampersands (&) that mark the keyboard access keys.
