L’exemple suivant montre comment configurer un InkCanvas pour reconnaître des mouvements d’application.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);

                     ApplicationGesture.ArrowDown,
                     ApplicationGesture.Circle});
}
' Add this code to the contstructor or OnLoaded method.
If (inkCanvas1.IsGestureRecognizerAvailable) Then

    inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture

    Dim gestures() As ApplicationGesture = _
                        {ApplicationGesture.Down, _
                         ApplicationGesture.ArrowDown, _
                         ApplicationGesture.Circle}

    inkCanvas1.SetEnabledGestures(gestures)
