備註

當專案捕捉到滑鼠時, 不論游標是否在其框線內, 都會收到滑鼠輸入。When an element captures the mouse, it receives mouse input whether or not the cursor is within its borders.

這是附加事件。This is an attached event. WPFWPF將附加事件實作為路由事件。implements attached events as routed events. 附加事件基本上是參考XAMLXAML事件的一種語言概念, 可以在未定義該事件的物件上處理, 這WPFWPF也會讓事件通過路由來進行擴充。Attached events are fundamentally a XAMLXAML language concept for referencing events that can be handled on objects that do not define that event, which WPFWPF expands upon by also enabling the event to traverse a route. 附加事件在程式碼中沒有直接處理語法;若要在程式碼中附加路由事件的處理常式, 您可以使用指定的 Add * 處理常式方法。Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, you use a designated Add*Handler method. 如需詳細資訊, 請參閱附加事件總覽For details, see Attached Events Overview.

由於反升路由的原因, 具有 capture 的實際元素可能是子項目, 不一定是事件處理常式實際附加的專案。Because of the bubbling routing, the actual element that has capture might be a child element, not necessarily the element where the event handler is actually attached. 檢查事件Source引數中的, 以判斷具有滑鼠捕捉的實際元素。Check the Source in the event arguments to determine the actual element that has mouse capture.
