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

'Declaration
Public Event Gesture As InkCanvasGestureEventHandler
'Usage
Dim instance As InkCanvas
Dim handler As InkCanvasGestureEventHandler

AddHandler instance.Gesture, handler

/** @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) 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
