ContextNodeBase.CreateSubNode 方法

项目
10/28/2008

创建一个新的子 ContextNodeBase 对象。

命名空间： System.Windows.Ink.AnalysisCore
程序集： IACore（在 IACore.dll 中）

语法

声明
Public Function CreateSubNode ( _
    type As Guid _
) As ContextNodeBase
用法
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

参数

type
类型：System.Guid
要创建的上下文节点的类型。使用 ContextNodeTypeBase 类中定义的某个 GUID 指定要创建的类型。

返回值

类型：System.Windows.Ink.AnalysisCore.ContextNodeBase
为此 ContextNodeBase 新创建的子 ContextNodeBase 对象。

备注

如果存在现有子节点，新创建的 ContextNodeBase 将添加为 SubNodes 集合中的最后一个子级。

示例

此示例获取所有行，并将这些行放入各自的段落中。它使用 InkAnalyzerBase (theInkAnalyzerBase) 中的行，为每一行新建一个段落子节点，然后将这些行的父级重新设置为这些新段落。

' 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);
}
