InkAnalyzerBase.ContextNodeMovingToPositionBase 事件
在筆墨分析器將 ContextNodeBase 移到其父節點 SubNodes 集合內的新位置之前發生。
命名空間: System.Windows.Ink.AnalysisCore
組件: IACore (在 IACore.dll 中)
語法
'宣告
Public Event ContextNodeMovingToPositionBase As ContextNodeMovingToPositionBaseEventHandler
'用途
Dim instance As InkAnalyzerBase
Dim handler As ContextNodeMovingToPositionBaseEventHandler
AddHandler instance.ContextNodeMovingToPositionBase, handler
public event ContextNodeMovingToPositionBaseEventHandler ContextNodeMovingToPositionBase
public:
event ContextNodeMovingToPositionBaseEventHandler^ ContextNodeMovingToPositionBase {
void add (ContextNodeMovingToPositionBaseEventHandler^ value);
void remove (ContextNodeMovingToPositionBaseEventHandler^ value);
}
/** @event */
public void add_ContextNodeMovingToPositionBase (ContextNodeMovingToPositionBaseEventHandler value)
/** @event */
public void remove_ContextNodeMovingToPositionBase (ContextNodeMovingToPositionBaseEventHandler 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 InkAnalyzerBase 的資料結構同步處理。這個事件會在筆墨分析的協調階段,或是回應在父節點的 SubNodes 集合內移動 ContextNodeBase 的筆墨分析器方法時發生。
如需將應用程式資料與 InkAnalyzerBase 進行同步處理的詳細資訊,請參閱Data Proxy with Ink Analysis。
範例
下列範例會定義 AttachDataProxyEventHandlers 方法,將資料 Proxy 事件處理常式附加至 InkAnalyzerBase,也就是 baseInkAnalyzer。
Private Sub AttachDataProxyEventHandlers()
' If the document model supports on demand data proxy, then add an
' event handler for the PopulateContextNodeBase event. This event is raised
' when the InkAnalyzerBase accesses a partially populated ContextNodeBase
' created by the document model.
If Me.baseDocumentModel.SupportsOnDemandDataProxy Then
AddHandler Me.baseInkAnalyzer.PopulateContextNodeBase, AddressOf Me.PopulateContextNodeBase
End If
' Add the other data proxy related event handlers. These events are raised
' by the InkAnalyzer to communicate parsing results to the document model.

下列範例會定義用來處理 ContextNodeMovingToPositionBase 事件的 MoveContextNodeBaseToPosition 方法。事件資訊會傳遞至 baseDocumentModel 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。
