InkAnalyzer.ContextNodeMovingToPosition 事件
在 InkAnalyzer 將 ContextNode 移到 ContextNode.SubNodes 集合中的新位置之前發生。
命名空間: Microsoft.Ink
組件: Microsoft.Ink.Analysis (在 Microsoft.Ink.Analysis.dll 中)
語法
'宣告
Public Event ContextNodeMovingToPosition As ContextNodeMovingToPositionEventHandler
'用途
Dim instance As InkAnalyzer
Dim handler As ContextNodeMovingToPositionEventHandler
AddHandler instance.ContextNodeMovingToPosition, handler
public event ContextNodeMovingToPositionEventHandler ContextNodeMovingToPosition
public:
event ContextNodeMovingToPositionEventHandler^ ContextNodeMovingToPosition {
void add (ContextNodeMovingToPositionEventHandler^ value);
void remove (ContextNodeMovingToPositionEventHandler^ value);
}
/** @event */
public void add_ContextNodeMovingToPosition (ContextNodeMovingToPositionEventHandler value)
/** @event */
public void remove_ContextNodeMovingToPosition (ContextNodeMovingToPositionEventHandler 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,或是回應移動其父代 SubNodes 集合內 ContextNode 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.

下列範例會定義用來處理 ContextNodeMovingToPosition 事件的 MoveContextNodeToPosition 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。
