發行項

表示二維區域的 ContextNode，其中可能有存在於應用程式中的任何非筆墨文字單字。

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

語法

'宣告
Public NotInheritable Class TextWordNode _
    Inherits ContextNode
'用途
Dim instance As TextWordNode

public sealed class TextWordNode : ContextNode

public ref class TextWordNode sealed : public ContextNode

public final class TextWordNode extends ContextNode

public final class TextWordNode extends ContextNode

備註

InkAnalyzer 不會產生 TextWordNode 物件。應用程式會使用 ContextNode.CreateSubNode 方法，將 TextWordNode 物件加入至內容節點樹狀目錄。如果分析器的狀態為永續性，這些節點也會是永續性。

未來的辨識器可能會使用 TextWordNode 物件所定義的區域，判斷是否有任何筆墨標註非筆墨的單字。

TextWordNode 不能有任何子系。

範例

下列範例會將 TextWordNode 物件加入至 TextBox (英文) 控制項 ( theTextBox) 的 InkAnalyzer (theInkAnalyzer)。範例中會將 TextBox (英文) 控制項的位置從像素座標轉換為筆墨座標。它會將 TextWordNode 物件的 Data 屬性設定為 TextBox (英文) 的 Text (英文) 屬性。

Dim writingRegion As WritingRegionNode = _
