Espacio de nombres: System.Windows.Ink.AnalysisCore
Ensamblado: IACore (en IACore.dll)

Sintaxis

'Declaración
Public Function CreateSubNode ( _
    type As Guid _
) As ContextNodeBase
'Uso
Dim instance As ContextNodeBase
Dim type As Guid
Dim returnValue As ContextNodeBase

returnValue = instance.CreateSubNode(type)

public ContextNodeBase CreateSubNode(
    Guid type
)

public:
ContextNodeBase^ CreateSubNode(
    Guid type
)

public ContextNodeBase CreateSubNode(
    Guid type
)

public function CreateSubNode(
    type : Guid
) : ContextNodeBase

Parámetros

type
Tipo: System.Guid
Tipo de nodo de contexto que se va a crear. Utilice uno de los GUID definidos en la clase ContextNodeTypeBase para especificar qué tipo desea crear.

Valor devuelto

Tipo: System.Windows.Ink.AnalysisCore.ContextNodeBase
El objeto ContextNodeBase creado recientemente cuyo elemento primario es este objeto ContextNodeBase.

Comentarios

Si ya existen nodos secundarios, el objeto ContextNodeBase creado recientemente se agrega como el último elemento secundario de la colección de SubNodes.

Ejemplos

En este ejemplo, se toman todas las líneas y se colocan en sus propios párrafos. Se utilizan las líneas de un objeto InkAnalyzerBase, theInkAnalyzerBase;, se crea un nuevo subnodo de párrafo para cada uno de ellos; y se cambia el elemento primario de las líneas para esos nuevos párrafos.

' 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);
}
