TextWordNode Class

Represents a ContextNode for a two-dimensional region where any non-ink text words may exist in the application.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)

public sealed class TextWordNode : ContextNode

The InkAnalyzer does not produce TextWordNode objects. The application uses the ContextNode.CreateSubNode method to add the TextWordNode objects to the context node tree. If the state of the analyzer is persisted, these nodes can be persisted as well.

Future recognizers may use the regions defined by the TextWordNode objects to determine if any ink annotates the non-ink word.

A TextWordNode cannot have any children.

The following example adds a TextWordNode object to an InkAnalyzer, theInkAnalyzer, for a TextBox control, theTextBox. It converts the location of the TextBox control from pixel coordinates to ink coordinates. It sets the Data property of the TextWordNode object to be the Text property of the TextBox.

// Add nodes to hold the TextWordNode
WritingRegionNode writingRegion = (WritingRegionNode)
ParagraphNode paragraph = (ParagraphNode)
LineNode line = (LineNode)

// Convert pixel coordinates to pixel coordinates and have the TextWordNode 
// be for the entire TextBox
Point topLeft = theTextBox.Location;
Point bottomRight = new Point(theTextBox.Right,
Graphics thePanelGraphics = theNotesPanel.CreateGraphics();
theInkCollector.Renderer.PixelToInkSpace(thePanelGraphics, ref topLeft);
theInkCollector.Renderer.PixelToInkSpace(thePanelGraphics, ref bottomRight);

// Create node for the word
TextWordNode textWord = (TextWordNode)

// Set location
Rectangle rectLocation = new Rectangle(topLeft,
    new Size(bottomRight.X - topLeft.X, bottomRight.Y - topLeft.Y));
textWord.SetLocation(new AnalysisRegion(rectLocation));

// Set the data property to be the text in the textbox.
textWord.Data = theTextBox.Text;
