Заметки
The exact definition of a paragraph is determined by the analyzing engines, but in general, a paragraph contains groups of lines that should reflow together.
A ParagraphNode object can contain the following types of children:
Any number of LineNode objects.
Any number of InkBulletNode objects.
Примеры
The following example takes all of the LineNode objects in the ContextNode tree of an InkAnalyzer, theInkAnalyzer, and puts them in their own ParagraphNode objects.
' Take each line and make it its own paragraph
Dim originalParagraphs As ContextNodeCollection = _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Paragraph)
Dim lines As ContextNodeCollection = _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In lines
' Create a new alignment level and paragraph
Dim lineParagraph As ContextNode = lineNode.ParentNode
Dim writingRegion As ContextNode = lineParagraph.ParentNode
Dim newParagraph As ParagraphNode = _
CType(writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph), ParagraphNode)
' Reparent the line
lineNode.Reparent(newParagraph)
Next lineNode
' Remove original paragraphs and alignment nodes
Dim originalParagraph As ContextNode
For Each originalParagraph In originalParagraphs
Dim originalAlignmentLevel As ContextNode = originalParagraph.ParentNode
originalAlignmentLevel.DeleteSubNode(originalParagraph)
originalAlignmentLevel.ParentNode.DeleteSubNode(originalAlignmentLevel)
Next originalParagraph
// Take each line and make it its own paragraph
ContextNodeCollection originalParagraphs =
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Paragraph);
ContextNodeCollection lines =
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
// Create a new paragraph
ContextNode paragraph = lineNode.ParentNode;
ContextNode writingRegion = paragraph.ParentNode;
ParagraphNode newParagraph = (ParagraphNode)
writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph);
// Reparent the line
lineNode.Reparent(newParagraph);
}
// Remove original paragraphs
foreach (ContextNode originalParagraph in originalParagraphs)
{
ContextNode originalWritingRegion = originalParagraph.ParentNode;
originalWritingRegion.DeleteSubNode(originalParagraph);
}
