설명
InkAnalyzer.RootNode 속성을 통해 RootNode에 액세스할 수 있습니다.
RootNode 개체에는 다음과 같은 형식의 자식이 포함될 수 있습니다.
UnclassifiedInkNode 개체(개수 제한 없음)
WritingRegionNode 개체(개수 제한 없음)
InkDrawingNode 개체(개수 제한 없음)
ImageNode 개체(개수 제한 없음)
AnalysisHintNode 개체(개수 제한 없음)
CustomRecognizerNode 개체(개수 제한 없음)
예제
다음 예제에서는 InkAnalyzer인 theInkAnalyzer를 받아 해당 ContextNode 트리를 사용하여 TreeView인 theTreeView를 RootNode부터 채웁니다. 트리 뷰에서 노드를 선택하면 해당 스트로크가 빨간색으로 표시되도록 설정됩니다. Tag 속성은 트리 노드와 해당 노드가 나타내는 컨텍스트 노드 간을 매핑하는 데 사용됩니다.
