雖然此 路由事件總覽 看起來會遵循專案樹狀結構中的反升路由,但實際上是直接路由事件,會沿著元素樹狀結構逐一引發和 reraised ContentElementAlthough this Routed Events Overview seems to follow a bubbling route through an element tree, it actually is a direct routed event that is raised and reraised along the element tree by each ContentElement.

這個事件是數個相關事件的其中一個,可報告基礎事件的滑鼠按鍵細節 Mouse.MouseUp ,這是一種附加事件,會沿著事件路由中的每個元素來處理。This event is one of several related events that report the mouse-button specifics of an underlying Mouse.MouseUp event, which is an attached event that is processed by each element along an event route.

這個事件的引數會公開基礎事件的引數 Mouse.MouseUpThe arguments of this event expose the arguments of the underlying Mouse.MouseUp event. 如果該事件標示為沿著事件路由處理,則仍然會引發滑鼠按鍵特定事件;不過,必須透過明確呼叫來加入滑鼠按鍵特定事件的處理常式 AddHandler ,並使用選項來處理已標示為已處理的事件,以便成為事件的接聽項。If that event is marked as handled along the event route, the mouse-button specific events are still raised; however, handlers of the mouse-button specific events must be added by explicitly calling AddHandler, with the option to handle events that are already marked as handled, in order to be listeners to the event.

在概念上,您可以將此事件視為) 的 (和其他滑鼠按鍵事件,並 ContentElement 使用類別) 所提供的服務定義 (的「服務」 MouseConceptually, think of this event (and other mouse-button events on ContentElement) to be a mouse "service" (with the service definition provided by the Mouse class). 事件會增加不需要檢查滑鼠按鍵狀態的便利性, (在事件資料中的原始滑鼠事件的左向下) 。The event adds the convenience of not needing to check the mouse button states (left-right, up-down) of the original mouse events in the event data. 針對更先進的案例,例如檢查非標準按鈕的狀態,您可能需要在類別上使用 Api, Mouse 而不是在上使用 ContentElementFor more advanced scenarios, such as checking for states of non-standard buttons, you might need to use the APIs on the Mouse class rather than those on ContentElement.
