備註

MouseLeave路由事件概觀使用直接的事件處理路由策略。MouseLeave is a Routed Events Overview that uses the direct event handling routing strategy. 直接路由的事件不會引發路由;相反地,它們會以處理相同的項目引發的狀況。Direct routed events are not raised along a route; instead, they are handled in the same element where they are raised. 不過,它們會啟用路由的事件的行為,例如樣式中的事件觸發程序的其他層面。However, they do enable other aspects of routed event behavior, such as event triggers in styles.

雖然MouseLeave播放軌,當滑鼠離開項目,這個事件更多解譯為常值回報IsMouseOver屬性值已從truefalse這個項目上。Although MouseLeave tracks when the mouse leaves an element, this event more literally reports that the IsMouseOver property value has changed from true to false on this element.

此事件建立的別名Mouse.MouseLeave附加事件,此類別中,以便MouseLeave屬於類別的成員清單時ContentElement繼承為基底的項目。This event creates an alias for the Mouse.MouseLeave attached event for this class, so that MouseLeave is part of the class members list when ContentElement is inherited as a base element. 附加至事件處理常式MouseLeave事件會附加至基礎Mouse.MouseLeave附加事件,並接收相同的事件資料執行個體。Event handlers that are attached to the MouseLeave event are attached to the underlying Mouse.MouseLeave attached event and receive the same event data instance.
