Crée un objet ContextNodeBase enfant.

Espace de noms : System.Windows.Ink.AnalysisCore
Assembly : IACore (dans IACore.dll)

Syntaxe

'Déclaration
Public Function CreateSubNode ( _
    type As Guid _
) As ContextNodeBase
'Utilisation
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

Paramètres

type
Type : System.Guid
Type de nœud de contexte à créer. Utilisez l'un des GUID définis dans la classe ContextNodeTypeBase pour spécifier le type à créer.

Valeur de retour

Type : System.Windows.Ink.AnalysisCore.ContextNodeBase
Nouvel objet ContextNodeBase dont le parent est ce ContextNodeBase.

Notes

Lorsque des nœuds enfants existent déjà, le nouveau ContextNodeBase est ajouté en tant que dernier enfant dans la collection de SubNodes.

Exemples

Cet exemple place toutes les lignes dans leurs paragraphes respectifs. Il utilise les lignes d'un InkAnalyzerBase, theInkAnalyzerBase;, crée un sous-nœud de paragraphe pour chacun d'eux et assigne les lignes à ces nouveaux paragraphes.

' 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);
}
