    newParentNode As ContextNodeBase _
)
'Usage

Dim newParentNode As ContextNodeBase

instance.Reparent(newParentNode)

public void Reparent (
    ContextNodeBase newParentNode
)

public:
void Reparent (
    ContextNodeBase^ newParentNode
)

public void Reparent (
    ContextNodeBase newParentNode
)

public function Reparent (
    newParentNode : ContextNodeBase

Not applicable.

Parameters

newParentNode
The new parent of which this ContextNodeBase object will be a child.

Example

This example takes all the ContextNodeBase objects of Type Line and puts them into their own ContextNodeBase objects, which are of type Paragraph. It uses the lines from an InkAnalyzerBase, theInkAnalyzerBase; creates a new paragraph subnode for each of them; reparents the lines to those new paragraphs; and deletes the original paragraphs.

' Take each line and make it its own paragraph
Dim originalParagraphs As ContextNodeBaseCollection = _
    theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Paragraph)
Dim lines As ContextNodeBaseCollection = _
    theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line)
Dim lineNode As ContextNodeBase
For Each lineNode In lines
    ' Create a new alignment level and paragraph
    Dim lineParagraph As ContextNodeBase = lineNode.ParentNode
    Dim writingRegion As ContextNodeBase = lineParagraph.ParentNode
    Dim newParagraph As ContextNodeBase = _
        writingRegion.CreateSubNode(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Paragraph)
    ' Reparent the line
    lineNode.Reparent(newParagraph)
Next lineNode
' Remove original paragraphs and alignment nodes
Dim originalParagraph As ContextNodeBase
For Each originalParagraph In originalParagraphs
    Dim originalAlignmentLevel As ContextNodeBase = originalParagraph.ParentNode
    originalAlignmentLevel.DeleteSubNode(originalParagraph)
    originalAlignmentLevel.ParentNode.DeleteSubNode(originalAlignmentLevel)
Next originalParagraph

// Take each line and make it its own paragraph
ContextNodeBaseCollection originalParagraphs =
    theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Paragraph);
ContextNodeBaseCollection lines =
    theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line);
foreach (ContextNodeBase lineNode in lines)
{
    // Create a new paragraph
    ContextNodeBase paragraph = lineNode.ParentNode;
    ContextNodeBase writingRegion = paragraph.ParentNode;
    ContextNodeBase newParagraph =
        writingRegion.CreateSubNode(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Paragraph);
    // Reparent the line
    lineNode.Reparent(newParagraph);
}
// Remove original paragraphs 
foreach (ContextNodeBase originalParagraph in originalParagraphs)
{
    ContextNodeBase originalWritingRegion = originalParagraph.ParentNode;
    originalWritingRegion.DeleteSubNode(originalParagraph);
}
