' digitizer.
Private currentStylus As Integer
<span space="preserve">...
</span> ' If the element loses focus, stop collecting the points and don't
' perform gesture recognition.
Protected Overrides Sub OnStylusLeave(ByVal rawStylusInput As RawStylusInput, ByVal confirmed As Boolean)
If confirmed Then
' Clear the StylusPointCollection
points = Nothing
currentStylus = 0
End If
End Sub 'OnStylusLeave
// StylusPointCollection that contains the stylus points of the current
// stroke.
StylusPointCollection points;
// Keeps track of the stylus to check whether two styluses are used on the
// digitizer.
int currentStylus;
<span space="preserve">...
</span> // If the element loses focus, stop collecting the points and don't
// perform gesture recognition.
