public:
 virtual System::Windows::DependencyObject ^ PredictFocus(System::Windows::Input::FocusNavigationDirection direction);
public virtual System.Windows.DependencyObject PredictFocus (System.Windows.Input.FocusNavigationDirection direction);
abstract member PredictFocus : System.Windows.Input.FocusNavigationDirection -> System.Windows.DependencyObject
override this.PredictFocus : System.Windows.Input.FocusNavigationDirection -> System.Windows.DependencyObject
Public Overridable Function PredictFocus (direction As FocusNavigationDirection) As DependencyObject

參數
