實作

備註

StylusLeave是使用直接事件處理路由策略的路由事件StylusLeave is a routed event that uses the direct event handling routing strategy. 直接路由事件不會沿著路由引發;相反地, 它們會在引發它們的相同專案中進行處理。Direct routed events are not raised along a route; instead, they are handled in the same element where they are raised. 不過, 它們會啟用路由事件行為的其他層面, 例如樣式中的事件觸發程式。However, they do enable other aspects of routed event behavior, such as event triggers in styles.

雖然StylusLeave會追蹤手寫筆離開專案範圍的時間, 但此事件實際上會報告屬性值IsStylusOver已從true變更為false這個專案上的。Although StylusLeave tracks when the stylus leaves the bounds of an element, this event more literally reports that the IsStylusOver property value has changed from true to false on this element.

這個事件StylusLeave會為這個類別建立Stylus.StylusLeave附加事件的別名, 因此當繼承為基底專案時UIElement , 就是類別成員清單的一部分。This event creates an alias for the Stylus.StylusLeave attached event for this class, so that StylusLeave is part of the class members list when UIElement is inherited as a base element. 附加至StylusLeave事件的事件處理常式會附加至基礎Stylus.StylusLeave附加事件, 並接收相同的事件資料實例。Event handlers that are attached to the StylusLeave event are attached to the underlying Stylus.StylusLeave attached event and receive the same event data instance.

觸控、滑鼠和手寫筆輸入存在於特定的關聯性中。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.
