InkCanvasGestureEventHandler

The following example demonstrates how to set up an InkCanvas to recognize application gestures.

// Add this code to the contstructor or OnLoaded method. 
if (inkCanvas1.IsGestureRecognizerAvailable)
{
    inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture;
    inkCanvas1.Gesture += new InkCanvasGestureEventHandler(inkCanvas1_Gesture);
    inkCanvas1.SetEnabledGestures(new ApplicationGesture[] 
                    {ApplicationGesture.Down, 
                     ApplicationGesture.ArrowDown,
                     ApplicationGesture.Circle});
}


...


void inkCanvas1_Gesture(object sender, InkCanvasGestureEventArgs e)
{
    ReadOnlyCollection<GestureRecognitionResult> gestureResults = 
        e.GetGestureRecognitionResults();

    // Check the first recognition result for a gesture. 
    if (gestureResults[0].RecognitionConfidence == 
        RecognitionConfidence.Strong)
    {
        switch (gestureResults[0].ApplicationGesture)
        {
            case ApplicationGesture.Down:
                // Do something. 
                break;
            case ApplicationGesture.ArrowDown:
                // Do something. 
                break;
            case ApplicationGesture.Circle:
                // Do something. 
                break;
        }

    }
