StylusPlugIn.OnStylusMove Method

Occurs on a pen thread when the tablet pen moves on the digitizer.

Namespace:  System.Windows.Input.StylusPlugIns
Assembly:  PresentationCore (in PresentationCore.dll)

protected virtual void OnStylusMove(
	RawStylusInput rawStylusInput


Type: System.Windows.Input.StylusPlugIns.RawStylusInput

A RawStylusInput that contains information about input from the pen.

This method occurs on a pen thread, so minimize work in this method to avoid impacting performance.

The following example demonstrates how to override the OnStylusMove method. To create a StylusPlugIn that restricts ink to a certain area, see the StylusPlugIn overview.

protected override void OnStylusMove(RawStylusInput rawStylusInput)
    // Run the base class before modifying the data 

    // Get the StylusPoints that have come in
    StylusPointCollection stylusPoints = rawStylusInput.GetStylusPoints();

    // Modify the (X,Y) data to move the points  
    // inside the acceptable input area, if necessary 
    for (int i = 0; i < stylusPoints.Count; i++)
        StylusPoint sp = stylusPoints[i];
        if (sp.X < 50) sp.X = 50;
        if (sp.X > 250) sp.X = 250;
        if (sp.Y < 50) sp.Y = 50;
        if (sp.Y > 250) sp.Y = 250;
        stylusPoints[i] = sp;

    // Copy the modified StylusPoints back to the RawStylusInput
