Form.OnInputLanguageChanging(InputLanguageChangingEventArgs) Form.OnInputLanguageChanging(InputLanguageChangingEventArgs) Form.OnInputLanguageChanging(InputLanguageChangingEventArgs) Form.OnInputLanguageChanging(InputLanguageChangingEventArgs) Method

定义

引发 InputLanguageChanging 事件。Raises the InputLanguageChanging event.

protected:
 virtual void OnInputLanguageChanging(System::Windows::Forms::InputLanguageChangingEventArgs ^ e);
protected virtual void OnInputLanguageChanging (System.Windows.Forms.InputLanguageChangingEventArgs e);
abstract member OnInputLanguageChanging : System.Windows.Forms.InputLanguageChangingEventArgs -> unit
override this.OnInputLanguageChanging : System.Windows.Forms.InputLanguageChangingEventArgs -> unit
Protected Overridable Sub OnInputLanguageChanging (e As InputLanguageChangingEventArgs)

参数

注解

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息,请参阅处理和引发事件For more information, see Handling and Raising Events.

OnInputLanguageChanging 方法还允许派生类对事件进行处理而不必附加委托。The OnInputLanguageChanging method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

在派生类中重写 OnInputLanguageChanging(InputLanguageChangingEventArgs) 时,一定要调用基类的 OnInputLanguageChanging(InputLanguageChangingEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnInputLanguageChanging(InputLanguageChangingEventArgs) in a derived class, be sure to call the base class's OnInputLanguageChanging(InputLanguageChangingEventArgs) method so that registered delegates receive the event.
