InkAnalyzer.ContextNodeLinkDeleting 事件

發行項
10/29/2008

InkAnalyzer 在兩個 ContextNode 物件之間刪除 ContextLink 之前發生。

命名空間： Microsoft.Ink
組件： Microsoft.Ink.Analysis (在 Microsoft.Ink.Analysis.dll 中)

語法

'宣告
Public Event ContextNodeLinkDeleting As ContextNodeLinkDeletingEventHandler
'用途
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)

JScript 不支援事件。

備註

當您的應用程式維護本身的資料結構時使用這個事件，該資料結構會與 InkAnalyzer 的資料結構同步處理。這個事件會在筆墨分析的協調階段，或是回應從 ContextNode 移除 ContextLink 的 InkAnalyzer 方法時發生。

如需將應用程式資料與 InkAnalyzer 進行同步處理的詳細資訊，請參閱Data Proxy with Ink Analysis。

範例

這個範例會定義 AttachDataProxyEventHandlers 方法，將資料 Proxy 事件處理常式附加至 InkAnalyzer，也就是 theInkAnalyzer。

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

下列範例會定義用來處理 ContextNodeLinkDeleting 事件的 RemoveContextNodeLink 方法。事件資訊會傳遞至 theDocumentModel 文件模型物件。

這個範例並未提供文件模型的定義，也未示範處理傳入資訊的方式。
