ContextNode.CreateSubNode Method

Creates a new child ContextNode object.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.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 function CreateSubNode(
    type : Guid
) : ContextNode

Parameters

  • type
    Type: System.Guid

    The type of context node to create. Use one of the GUIDs defined in the ContextNodeType class to specify which type to create.

Return Value

Type: Microsoft.Ink.ContextNode
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.

If your application inadvertently tries to add an improper node—for example, a writing region where an ImageNode node is expected—the code throws an exception from CreateSubNode.

Examples

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(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);
            }
