實作
備註
此事件 Stylus.PreviewStylusInRange 會為這個類別建立附加事件的別名，因此 PreviewStylusInRange 當 UIElement 繼承為基底專案時，它就是類別成員清單的一部分。This event creates an alias for the Stylus.PreviewStylusInRange attached event for this class, so that PreviewStylusInRange is part of the class members list when UIElement is inherited as a base element. 附加至事件的事件處理常式 PreviewStylusInRange 會附加至基礎 Stylus.PreviewStylusInRange 附加事件，並接收相同的事件資料實例。Event handlers that are attached to the PreviewStylusInRange event are attached to the underlying Stylus.PreviewStylusInRange attached event and receive the same event data instance.
觸控、滑鼠和手寫筆輸入存在於特定關聯性中。Touch, mouse, and stylus input exist in a particular relationship. 如需詳細資訊，請參閱 輸入總覽。For more information, see Input Overview.
