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) Then
inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture
Dim gestures() As ApplicationGesture = _
{ApplicationGesture.Down, _
ApplicationGesture.ArrowDown, _
ApplicationGesture.Circle}
inkCanvas1.SetEnabledGestures(gestures)
End If
...
Sub inkCanvas1_Gesture(ByVal sender As Object, _
ByVal e As InkCanvasGestureEventArgs) Handles inkCanvas1.Gesture
Dim gestureResults As ReadOnlyCollection(Of GestureRecognitionResult)
gestureResults = e.GetGestureRecognitionResults()
' Check the first recognition result for a gesture.
If gestureResults(0).RecognitionConfidence = _
RecognitionConfidence.Strong Then
Select Case gestureResults(0).ApplicationGesture
Case ApplicationGesture.Down
' Do something.
Case ApplicationGesture.ArrowDown
' Do something.
Case ApplicationGesture.Circle
' Do something.
End Select
End If
End Sub 'inkCanvas1_Gesture
