项目
11/04/2008

表示 ContextNode 对象集合的 ContextNode，这些对象组成行的逻辑组。

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

语法

声明
Public NotInheritable Class ParagraphNode _
    Inherits ContextNode
用法
Dim instance As ParagraphNode

public sealed class ParagraphNode : ContextNode

public ref class ParagraphNode sealed : public ContextNode

public final class ParagraphNode extends ContextNode

public final class ParagraphNode extends ContextNode

备注

段落的精确定义由分析引擎确定，但通常情况下，段落包含会重新流到一起的若干组行。

ParagraphNode 对象可包含任意数目的下列类型的子级：

LineNode 对象。
InkBulletNode 对象。

示例

下面的示例取用某 InkAnalyzer, theInkAnalyzer 的 ContextNode 树中的所有 LineNode 对象，并将它们放置到各自的 ParagraphNode 对象中。

' Take each line and make it its own paragraph
Dim originalParagraphs As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Paragraph)

Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line)

For Each lineNode As ContextNode In lines
    ' Create a new paragraph
    Dim paragraph As ContextNode = lineNode.ParentNode
    Dim writingRegion As ContextNode = paragraph.ParentNode
    Dim newParagraph As ParagraphNode = CType(writingRegion.CreateSubNode(ContextNodeType.Paragraph), ParagraphNode)
    ' Reparent the line
    lineNode.Reparent(newParagraph)
Next lineNode

' Remove original paragraphs 
For Each originalParagraph As ContextNode In originalParagraphs
    Dim originalWritingRegion As ContextNode = originalParagraph.ParentNode
    originalWritingRegion.DeleteSubNode(originalParagraph)
Next originalParagraph

// Take each line and make it its own paragraph
ContextNodeCollection originalParagraphs =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Paragraph);
ContextNodeCollection lines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
    // Create a new paragraph
    ContextNode paragraph = lineNode.ParentNode;
    ContextNode writingRegion = paragraph.ParentNode;
    ParagraphNode newParagraph = (ParagraphNode)
        writingRegion.CreateSubNode(ContextNodeType.Paragraph);
    // Reparent the line
    lineNode.Reparent(newParagraph);
}
// Remove original paragraphs 
foreach (ContextNode originalParagraph in originalParagraphs)
{
    ContextNode originalWritingRegion = originalParagraph.ParentNode;
    originalWritingRegion.DeleteSubNode(originalParagraph);
}
