‘선언
Public Event ContextNodeMovingToPositionBase As ContextNodeMovingToPositionBaseEventHandler
‘사용 방법
Dim instance As InkAnalyzerBase

public:

JScript에서는 이벤트를 지원하지 않습니다.

설명

응용 프로그램에서 InkAnalyzerBase의 데이터 구조와 동기화되는 자체 데이터 구조를 유지하는 경우 이 이벤트를 사용합니다. 이 이벤트는 잉크 분석의 조정 단계에 발생하거나 ContextNodeBase를 부모 노드의 SubNodes 컬렉션 내에서 이동하는 잉크 분석기 메서드에 대한 응답으로 발생합니다.

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