示例1: InterpretScratchoutGesture
Private Function InterpretScratchoutGesture(ByVal stroke As Stroke) As Boolean
' Attempt to instantiate a recognizer for scratchout gestures.
Dim gestures() As ApplicationGesture = {ApplicationGesture.ScratchOut}
Dim recognizer As New GestureRecognizer(gestures)
If Not recognizer.IsRecognizerAvailable Then
Return False
End If
' Determine if the stroke was a scratchout gesture.
Dim gestureStrokes As StrokeCollection = New StrokeCollection()
gestureStrokes.Add(stroke)
Dim results As ReadOnlyCollection(Of GestureRecognitionResult)
results = recognizer.Recognize(gestureStrokes)
If results.Count = 0 Then
Return False
End If
' Results are returned sorted in order strongest-to-weakest;
' we need only analyze the first (strongest) result.
If (results(0).ApplicationGesture = ApplicationGesture.ScratchOut) Then
' Use the scratchout stroke to perform hit-testing and
' erase existing strokes, as necessary.
Return True
Else
' Not a gesture: display the stroke normally.
Return False
End If
End Function
