Represents a ContextNode for a collection of ContextNode objects that make up a logical grouping of lines.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)

Syntax

'Declaration
Public NotInheritable Class ParagraphNode _
    Inherits ContextNode
'Usage
Dim instance As ParagraphNode

public sealed class ParagraphNode : ContextNode

public ref class ParagraphNode sealed : public ContextNode

public final class ParagraphNode extends ContextNode

Remarks

The exact definition of a paragraph is determined by the analyzing engines, but in general, a paragraph contains groups of lines that should reflow together.

A ParagraphNode object can contain the following types of children:

Any number of LineNode objects.
Any number of InkBulletNode objects.

Examples

The following example takes all of the LineNode objects in the ContextNode tree of an InkAnalyzer, theInkAnalyzer, and puts them in their own ParagraphNode objects.

' 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);
            }
