InkCanvas.Gesture Event

Occurs when the InkCanvas detects a gesture.

Namespace: System.Windows.Controls
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public event InkCanvasGestureEventHandler Gesture
/** @event */
public void add_Gesture (InkCanvasGestureEventHandler value)

/** @event */
public void remove_Gesture (InkCanvasGestureEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
<object Gesture="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;
            }

        }
    }
