InkAnalyzer.StrokesReparented イベント

2008-10-28

InkAnalyzer が ContextNode から別の場所に Stroke を移動した場合に発生します。

名前空間 : Microsoft.Ink
アセンブリ : Microsoft.Ink.Analysis (Microsoft.Ink.Analysis.dll 内)

構文

'宣言
Public Event StrokesReparented As StrokesReparentedEventHandler
'使用
Dim instance As InkAnalyzer
Dim handler As StrokesReparentedEventHandler

AddHandler instance.StrokesReparented, handler

public event StrokesReparentedEventHandler StrokesReparented

public:
 event StrokesReparentedEventHandler^ StrokesReparented {
    void add (StrokesReparentedEventHandler^ value);
    void remove (StrokesReparentedEventHandler^ value);
}

/** @event */
public void add_StrokesReparented (StrokesReparentedEventHandler value)
/** @event */
public void remove_StrokesReparented (StrokesReparentedEventHandler value)

JScript では、イベントは使用できません。

解説

このイベントは、アプリケーションが InkAnalyzer のデータ構造と同期されている独自のデータ構造を保持している場合に使用します。このイベントは、インク分析の調整段階で、またはある ContextNode から別の場所に Stroke を移動する InkAnalyzer メソッドへの応答として発生します。

アプリケーションデータと InkAnalyzer の同期の詳細については、「Data Proxy with Ink Analysis」を参照してください。

例

この例では、データプロキシイベントハンドラを InkAnalyzer、theInkAnalyzer にアタッチする AttachDataProxyEventHandlers メソッドを定義します。

Private Sub AttachDataProxyEventHandlers() 
    ' If the document model supports on demand data proxy, then add an
    ' event handler for the PopulateContextNode event. This event is raised
    ' when the InkAnalyzer accesses a partially populated ContextNode created
    ' by the document model.
    If Me.theDocumentModel.SupportsOnDemandDataProxy Then
        AddHandler Me.theInkAnalyzer.PopulateContextNode, AddressOf Me.PopulateContextNode
    End If

    ' Add the other data proxy related event handlers. These events are raised
    ' by the InkAnalyzer to communicate ink analysis results to the document model.
    AddHandler Me.theInkAnalyzer.ContextNodeCreated, AddressOf Me.AddContextNode
    AddHandler Me.theInkAnalyzer.ContextNodeDeleting, AddressOf Me.RemoveContextNode
    AddHandler Me.theInkAnalyzer.ContextNodeLinkAdding, AddressOf Me.AddContextNodeLink
    AddHandler Me.theInkAnalyzer.ContextNodeLinkDeleting, AddressOf Me.RemoveContextNodeLink
    AddHandler Me.theInkAnalyzer.ContextNodeMovingToPosition, AddressOf Me.MoveContextNodeToPosition
    AddHandler Me.theInkAnalyzer.ContextNodePropertiesUpdated, AddressOf Me.UpdateContextNodeProperties
    AddHandler Me.theInkAnalyzer.ContextNodeReparenting, AddressOf Me.ReparentContextNode
    AddHandler Me.theInkAnalyzer.InkAnalyzerStateChanging, AddressOf Me.InkAnalyzer_StateChanging
    AddHandler Me.theInkAnalyzer.StrokesReparented, AddressOf Me.ReparentStroke
    AddHandler Me.theInkAnalyzer.IntermediateResultsUpdated, AddressOf Me.ResultsAvailable
    AddHandler Me.theInkAnalyzer.ResultsUpdated, AddressOf Me.ResultsAvailable

End Sub 'AttachDataProxyEventHandlers

        private void AttachDataProxyEventHandlers()

                new Microsoft.Ink.ContextNodeReparentingEventHandler(

                    this.ResultsAvailable);
        }

次の例では、StrokesReparented イベントを処理する ReparentStrokes メソッドを定義します。イベント情報は、ドキュメントモデルオブジェクト theDocumentModel に渡されます。

この例では、ドキュメントモデルを定義したり、ドキュメントモデルが渡された情報を処理する方法を示したりはしません。
