 virtual event System::Windows::Input::KeyboardFocusChangedEventHandler ^ GotKeyboardFocus;
public event System.Windows.Input.KeyboardFocusChangedEventHandler GotKeyboardFocus;
member this.GotKeyboardFocus : System.Windows.Input.KeyboardFocusChangedEventHandler 
Public Custom Event GotKeyboardFocus As KeyboardFocusChangedEventHandler 



IsKeyboardFocusedChanged是一個類似事件, 它會追蹤屬性中的狀態變更, 以維護元素的焦點狀態;在許多相同的情況下都會引發事件。GotKeyboardFocusIsKeyboardFocusedChanged is a similar event that tracks status changes in a property that maintains the focus state for an element; the GotKeyboardFocus event is raised in many of the same circumstances.

因為此事件使用反升路由, 所以具有焦點的元素可能是子項目, 而不是實際附加事件處理常式的專案。Because this event uses bubbling routing, the element that has focus might be a child element instead of the element where the event handler is actually attached. 檢查事件Source資料中的, 以判斷具有焦點的實際元素。Check the Source in the event data to determine the actual element that has focus.

這個事件會為這個類別建立Keyboard.GotKeyboardFocus附加事件的別名, 因此當GotKeyboardFocus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 Keyboard.GotKeyboardFocus attached event for this class so that GotKeyboardFocus is part of the class members list when UIElement is inherited as a base element. 附加至GotKeyboardFocus事件的事件處理常式會附加至基礎Keyboard.GotKeyboardFocus附加事件, 並接收相同的事件資料實例。Event handlers that are attached to the GotKeyboardFocus event are attached to the underlying Keyboard.GotKeyboardFocus attached event and receive the same event data instance.
