项目
11/04/2008

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

命名空间： Microsoft.Ink
程序集： Microsoft.Ink.Analysis（在 Microsoft.Ink.Analysis.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 对象可包含下列类型的子元素：

任意数目的 LineNode 对象。
任意数目的 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(Microsoft.Ink.ContextNodeType.Paragraph)
Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In lines
    ' Create a new alignment level and paragraph
    Dim lineParagraph As ContextNode = lineNode.ParentNode
    Dim writingRegion As ContextNode = lineParagraph.ParentNode
    Dim newParagraph As ParagraphNode = _
        CType(writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph), ParagraphNode)
    ' Reparent the line
    lineNode.Reparent(newParagraph)
Next lineNode
' Remove original paragraphs and alignment nodes
Dim originalParagraph As ContextNode
For Each originalParagraph In originalParagraphs
    Dim originalAlignmentLevel As ContextNode = originalParagraph.ParentNode
    originalAlignmentLevel.DeleteSubNode(originalParagraph)
    originalAlignmentLevel.ParentNode.DeleteSubNode(originalAlignmentLevel)
Next originalParagraph

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