ContextLink Class
Assembly: Microsoft.Ink.Analysis (in microsoft.ink.analysis.dll)
Examples of the relationship represented by a ContextLink relationship include:
-
A ParagraphNode that is encircled by an InkDrawingNode. A ContextLink object with a is created and added to the Links properties of both the ParagraphNode and the InkDrawingNode. The SourceNode is the InkDrawingNode and the DestinationNode is the ParagraphNode.
-
An AnalysisHintNode and a WritingRegionNode. When an AnalysisHintNode is used in ink analysis, a ContextLink is created between the WritingRegionNode and the AnalysisHintNode. The SourceNode is the AnalysisHintNode and the DestinationNode is the WritingRegionNode.
-
Two InkDrawingNode objects where a line is drawn between them, as in a flow chart.
To determine the relationship between SourceNode and DestinationNode uses the InkDrawingNode.SemanticType or WritingRegionNode.SemanticType property on the appropriate node.
The following example finds all the nodes that are linked to ContextNode node, selectedNode. If selectedNode is not a destination node, the destination node is added to an ArrayList, destinationNodes. If selectedNode is not the source node, it is added to an ArrayList, sourceNodes.
Dim destinationNodes As ArrayList = New ArrayList() Dim sourceNodes As ArrayList = New ArrayList() ' Find all the nodes that link to the currently selected node. Dim link As Microsoft.Ink.ContextLink For Each link In selectedNode.Links If link.DestinationNode <> selectedNode Then destinationNodes.Add(link.DestinationNode) End If If link.SourceNode <> selectedNode Then sourceNodes.Add(link.SourceNode) End If Next
The following example finds all WritingRegionNode objects in the node tree of an InkAnalyzer, theInkAnalyzerWithHint. It then puts those that are linked to an AnalysisHintNode with a Factoid of "IS_DATE_FULLDATE" into a ContextNodeCollection, writingRegionsWithFactoids.
Dim writingRegionsWithFactoids As _ New ContextNodeCollection(Me.theInkAnalyzerWithHint) Dim allWritingRegions As ContextNodeCollection = _ Me.theInkAnalyzerWithHint.FindNodesOfType( _ Microsoft.Ink.ContextNodeType.WritingRegion) Dim writingRegion As WritingRegionNode For Each writingRegion In allWritingRegions ' See if they are linked to any factoid Dim link As ContextLink For Each link In writingRegion.Links If link.SourceNode.Type = ContextNodeType.AnalysisHint Then Dim hint As AnalysisHintNode = _ CType(link.SourceNode, AnalysisHintNode) If hint.Factoid = "IS_DATE_FULLDATE" Then writingRegionsWithFactoids.Add(writingRegion) End If End If Next link Next writingRegion
