Параметры

type
Тип: System.Guid
The type of context node to create. Use one of the GUIDs defined in the ContextNodeTypeBase class to specify which type to create.

Возвращаемое значение

Тип: System.Windows.Ink.AnalysisCore.ContextNodeBase
The newly created ContextNodeBase object whose parent is this ContextNodeBase.

Заметки

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

Примеры

This example takes all the lines and puts them into their own paragraphs. It uses the lines from an InkAnalyzerBase, theInkAnalyzerBase; 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 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);
}
