ContextNodeTypeBase Class

Defines values that specify the type of ContextNode object.

Namespace:  System.Windows.Ink.AnalysisCore
Assembly:  IACore (in IACore.dll)

public sealed class ContextNodeTypeBase

The ContextNodeBase.Type property and the InkAnalyzerBase.FindNodesOfType method frequently use the fields of this class.

This example sets the Text property of a TextBox, selectedResultsTextBox, to show an appropriate string for a ContextNodeBase, selectedNode. It uses the Type property to choose the kind of text to show, depending on the type of the ContextNodeBase.

if (selectedNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) &&
   (selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.WritingRegion ||
    selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Paragraph ||
    selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.CustomRecognizer ||
    selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Object ||
    selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line))
{
    selectedResultsTextBox.Text =
        (string)selectedNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString);
}
else if (selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord)
{
    ContextNodeBase parentNode = selectedNode.ParentNode;
    if (parentNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line &&
        parentNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString))
    {
        // Put parent line's recognized string into the text box
        selectedResultsTextBox.Text =
            (string)parentNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString);

        // Select the text that corresponds to the ink word
        ContextNodeBaseCollection subNodes = new ContextNodeBaseCollection(theInkAnalyzerBase);
        subNodes.Add(selectedNode);
        int start;
        int length;
        theInkAnalyzerBase.GetTextRangeFromNodes(subNodes, out start, out length);
        if (start >= 0 && length > 0)
        {
            selectedResultsTextBox.Select(start, length);
        }
    }
}
else if (selectedNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing &&
         selectedNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName))
{
    selectedResultsTextBox.Text =
        (string)selectedNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName);
