아티클
10/28/2008

업데이트: 2007년 11월

InkAnalyzer에서 두 ContextNode 개체 사이의 ContextLink를 삭제하기 전에 발생합니다.

네임스페이스: Microsoft.Ink
어셈블리: Microsoft.Ink.Analysis(Microsoft.Ink.Analysis.dll)

구문

‘선언
Public Event ContextNodeLinkDeleting As ContextNodeLinkDeletingEventHandler
‘사용 방법
Dim instance As InkAnalyzer
Dim handler As ContextNodeLinkDeletingEventHandler

AddHandler instance.ContextNodeLinkDeleting, handler

public event ContextNodeLinkDeletingEventHandler ContextNodeLinkDeleting

public:
 event ContextNodeLinkDeletingEventHandler^ ContextNodeLinkDeleting {
    void add (ContextNodeLinkDeletingEventHandler^ value);
    void remove (ContextNodeLinkDeletingEventHandler^ value);
}

/** @event */
public void add_ContextNodeLinkDeleting (ContextNodeLinkDeletingEventHandler value)
/** @event */
public void remove_ContextNodeLinkDeleting (ContextNodeLinkDeletingEventHandler value)

JScript에서는 이벤트를 지원하지 않습니다.

설명

응용 프로그램에서 InkAnalyzer의 데이터 구조와 동기화되는 자체 데이터 구조를 유지하는 경우 이 이벤트를 사용합니다. 이 이벤트는 잉크 분석의 조정 단계에서 발생하거나 ContextNode에서 ContextLink를 제거하는 InkAnalyzer 메서드에 응답하여 발생합니다.

응용 프로그램 데이터와 InkAnalyzer를 동기화하는 방법에 대한 자세한 내용은 Data Proxy with Ink Analysis을를 참조하십시오.

다음 예제에서는 ContextNodeLinkDeleting 이벤트를 처리하는 RemoveContextNodeLink라는 메서드를 정의합니다. 이벤트 정보는 문서 모델 개체인 theDocumentModel에 전달됩니다.

이 예제에서는 문서 모델의 정의를 제공하거나 문서 모델에서 전달된 정보를 처리하는 방법을 보여 주지 않습니다.
