Hinweise

Im folgenden Beispiel wird veranschaulicht, wie Sie ein Objekt EllipseStylusShape erstellen und an die GetIncrementalStrokeHitTester Methode übergeben, um einen Teil eines Teils zu Strokelöschen. In diesem Beispiel wird davon ausgegangen, dass es einen IncrementalStrokeHitTester Aufruf eraseTester gibt und das StrokeHit Ereignis mit dem in diesem Beispiel definierten Ereignishandler verbunden wurde. Informationen zum Erstellen eines Steuerelements, mit dem ein Benutzer Freihand löschen kann, finden Sie unter How to: Erase Ink on a Custom Control.
