Assembly: IAWinFX (in iawinfx.dll)

Syntax

'Declaration
Public Function CreateSubNode ( _
    type As Guid _
) As ContextNode
'Usage
Dim instance As ContextNode
Dim type As Guid
Dim returnValue As ContextNode

returnValue = instance.CreateSubNode(type)

public ContextNode CreateSubNode (
    Guid type
)

public:
ContextNode^ CreateSubNode (
    Guid type
)

public ContextNode CreateSubNode (
    Guid type
)

public function CreateSubNode (
    type : Guid
) : ContextNode

Not applicable.

Parameters

type
The type of context node to create.

Return Value

The newly created ContextNode object whose parent is this ContextNode.

Remarks

When existing child nodes already exist, the newly created ContextNode is added as the last child in the collection of SubNodes.

Example

This example puts all the lines into their own paragraphs. It uses the lines from an InkAnalyzer, theInkAnalyzer; creates a new paragraph subnode for each of them; and reparents the lines to those new paragraphs.

' 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);
}
