命名空间：  System.Windows.Ink
程序集：  IAWinFX（在 IAWinFX.dll 中）

语法

声明
Public Property Data As Object
用法
Dim instance As TextWordNode
Dim value As Object

value = instance.Data

instance.Data = value

public Object Data { get; set; }

public:
property Object^ Data {
    Object^ get ();
    void set (Object^ value);
}

/** @property */
public Object get_Data()
/** @property */
public  void set_Data(Object value)

public function get Data () : Object
public function set Data (value : Object)

属性值

类型：System.Object
TextWordNode 对象的应用程序定义的数据。

备注

使用它可将您自己的数据添加到 TextWordNode 对象。

示例

下面的示例为名为 theTextBox 的 TextBox 控件将一个 TextWordNode 对象添加到名为 theInkAnalyzer 的 InkAnalyzer。该示例将 TextWordNode 对象的 Data 属性设置为 TextBox 的 Text 属性。

' Add nodes to hold the TextWordNode
Dim writingRegion As WritingRegionNode = _
    CType(theInkAnalyzer.RootNode.CreateSubNode(ContextNodeType.WritingRegion), _
    WritingRegionNode)

Dim paragraph As ParagraphNode = _
    CType(writingRegion.CreateSubNode(ContextNodeType.Paragraph), _
    ParagraphNode)

Dim line As LineNode = _
    CType(paragraph.CreateSubNode(ContextNodeType.Line), LineNode)

' Create node for the word
Dim textWord As TextWordNode = _
    CType(line.CreateSubNode(ContextNodeType.TextWord), TextWordNode)

' Set location
Dim textTop As Double = InkCanvas.GetTop(theTextBox)
Dim textLeft As Double = InkCanvas.GetLeft(theTextBox)

Dim rectLocation As New Rect(textLeft, textTop, theTextBox.Width, theTextBox.Height)
textWord.SetLocation(New AnalysisRegion(rectLocation))

' Set the data property to be the text in the textbox.
textWord.Data = theTextBox.Text

// Add nodes to hold the TextWordNode
WritingRegionNode writingRegion = (WritingRegionNode)
    theInkAnalyzer.RootNode.CreateSubNode(ContextNodeType.WritingRegion);
ParagraphNode paragraph = (ParagraphNode)
    writingRegion.CreateSubNode(ContextNodeType.Paragraph);
LineNode line = (LineNode)
    paragraph.CreateSubNode(ContextNodeType.Line);

// Create node for the word
TextWordNode textWord = (TextWordNode)
    line.CreateSubNode(ContextNodeType.TextWord);


// Set location
double textTop = InkCanvas.GetTop(theTextBox);
double textLeft = InkCanvas.GetLeft(theTextBox);

Rect rectLocation = new Rect(textLeft, textTop, theTextBox.Width, theTextBox.Height);
textWord.SetLocation(new AnalysisRegion(rectLocation));

// Set the data property to be the text in the textbox.
textWord.Data = theTextBox.Text;
