ContentElement.OnPreviewMouseRightButtonUp(MouseButtonEventArgs) ContentElement.OnPreviewMouseRightButtonUp(MouseButtonEventArgs) ContentElement.OnPreviewMouseRightButtonUp(MouseButtonEventArgs) ContentElement.OnPreviewMouseRightButtonUp(MouseButtonEventArgs) Method

定義

當未處理的 PreviewMouseRightButtonUp 路由事件到達其路由中衍生自此類別的項目時叫用。Invoked when an unhandled PreviewMouseRightButtonUp routed event reaches an element in its route that is derived from this class. 實作這個方法可為此事件加入類別處理。Implement this method to add class handling for this event.

protected public:
 virtual void OnPreviewMouseRightButtonUp(System::Windows::Input::MouseButtonEventArgs ^ e);
protected internal virtual void OnPreviewMouseRightButtonUp (System.Windows.Input.MouseButtonEventArgs e);
abstract member OnPreviewMouseRightButtonUp : System.Windows.Input.MouseButtonEventArgs -> unit
override this.OnPreviewMouseRightButtonUp : System.Windows.Input.MouseButtonEventArgs -> unit
Protected Friend Overridable Sub OnPreviewMouseRightButtonUp (e As MouseButtonEventArgs)

參數

包含事件資料的 MouseButtonEventArgsThe MouseButtonEventArgs that contains the event data. 事件資料會報告已放開滑鼠右鍵。The event data reports that the right mouse button was released.

備註

PreviewMouseRightButtonUp事件看起來是旅遊通道路線, 但實際上是以間接方式移動。The PreviewMouseRightButtonUp event appears to travel a tunneling route but actually travels in an indirect way. Mouse.PreviewMouseUp是以通道路由傳送的基礎事件, 而每ContentElement個事件路由都會使用相同的處理來引發直接路由事件PreviewMouseRightButtonUpMouse.PreviewMouseUp is the underlying event that is tunnel routed, and each ContentElement along the event route uses identical handling to raise the direct routed event PreviewMouseRightButtonUp. 雖然您可以將此PreviewMouseRightButtonUp專案的事件標示為已處理, 但已處理的狀態並不會沿著事件路由永久保存至其他元素。Although you can mark the PreviewMouseRightButtonUp event as handled for purposes of this element, the handled state does not perpetuate to other elements along the event route. 不過, 您可能會想要將事件標示為已處理, 以避免叫用一般實例處理常式 (未handledEventsToo指定的)。However, you might want to mark the event as handled in order to prevent general instance handlers (those that did not specify handledEventsToo) from being invoked.

ContentElement一般滑鼠事件處理的預設執行會Mouse.PreviewMouseUp接聽並將它轉換為適當的本機事件。The default implementation for general mouse event handling in ContentElement listens for Mouse.PreviewMouseUp and converts it to an appropriate local event. 如果您想要覆寫此邏輯, 您必須建立衍生類別。If you want to override this logic, you must create a derived class. 在衍生類別的靜態函式中, 註冊的替代類別處理常式Mouse.PreviewMouseUpIn the static constructor of your derived class, register an alternative class handler for Mouse.PreviewMouseUp. 您無法藉ContentElement由覆寫OnPreviewMouseRightButtonUp來變更的滑鼠處理行為。You cannot change the mouse handling behavior of ContentElement by overriding OnPreviewMouseRightButtonUp.
