ContextNode.CreateSubNode 方法

建立新的子 ContextNode 物件。

命名空間：  System.Windows.Ink
組件：  IAWinFX (在 IAWinFX.dll 中)

語法

'宣告
Public Function CreateSubNode ( _
    type As Guid _
) As ContextNode
'用途
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

參數

• type
  型別：System.Guid
  要建立的內容節點類型。

傳回值

型別：System.Windows.Ink.ContextNode
新建立的 ContextNode 物件有 ContextNode 做為其父代。

備註

當現有的子節點已經存在時，會加入新建立的 ContextNode 做為 SubNodes 集合中的最後一個子節點。

如果您的應用程式不慎嘗試加入不正確的節點 (例如，必須有 ImageNode 節點的書寫區域)，程式碼會從 CreateSubNode 擲回例外狀況。

範例

這個範例會將所有行放入這些行專屬的段落中。範例中會使用來自 InkAnalyzertheInkAnalyzer; 的行，為每一行建立新的段落子節點，並且將這些行的父代重設為這些新段落。

' 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);
}
