ContextNode.SetStrokes Method

Sets the specified strokes on a ContextNode object.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in microsoft.ink.analysis.dll)

public void SetStrokes (
	Strokes strokes
)
public void SetStrokes (
	Strokes strokes
)
public function SetStrokes (
	strokes : Strokes
)
Not applicable.

Parameters

strokes

The Strokes that ContextNode object acquires.

This method does not update the DirtyRegion.

If any of the specified strokes in the stroke collection are already set on the InkAnalyzer, an ArgumentExceptionArgumentException is thrown.

The following example is a method called PopulateNode, from sample code that uses a System.Windows.Forms.TreeViewSystem.Windows.Forms.TreeView as a document model to show how data proxy can be used to store and load a context node tree for an InkAnalyzer. The DocumentNodeData class stores the ContextNode data in the document model when the Tag property of each TreeNodeTreeNode object is set to a DocumentNodeData object.

The PopulateNode method fully populates a ContextNode object by adding strokes, property data, annotation type, child nodes, and links from an InkAnalyzer object. It uses SetStrokes to add the strokes. The data comes from the DocumentNodeData object that is obtained from the corresponding TreeNodeTreeNode.

  • this[analyzerNode.Id] is an indexer on the document model class that maps a GuidGuid to a TreeNodeTreeNode. (Me(analyzerNode.Id) in VB.NET)

  • AddLinksToAnalyer is a method on the document model class that adds links to the ContextNode.

After the node is fully populated, the PartiallyPopulated property is set to false.

    Microsoft.Ink.ContextNode analyzerNode,
    Microsoft.Ink.InkAnalyzer theInkAnalyzer)

            DocumentNodeData subNodeData = documentSubNode.Tag as DocumentNodeData;

            }
        }
