InputLanguageChangedEventHandler 代理人

  • 參考

定義

命名空間:
System.Windows.Forms
組件:
System.Windows.Forms.dll

代表將處理 InputLanguageChanged 之 Form 事件的方法。

public delegate void InputLanguageChangedEventHandler(System::Object ^ sender, InputLanguageChangedEventArgs ^ e);
public delegate void InputLanguageChangedEventHandler(object sender, InputLanguageChangedEventArgs e);
public delegate void InputLanguageChangedEventHandler(object? sender, InputLanguageChangedEventArgs e);
type InputLanguageChangedEventHandler = delegate of obj * InputLanguageChangedEventArgs -> unit
Public Delegate Sub InputLanguageChangedEventHandler(sender As Object, e As InputLanguageChangedEventArgs)

參數

sender
Object

事件的來源。

e
InputLanguageChangedEventArgs

包含事件資料的 InputLanguageChangedEventArgs。

範例

下列範例會建立新的 Form ，並將事件處理常式附加至 InputLanguageChanged 事件。 當輸入語言變更為日文時，此事件會變更 IMEmode 。

備註

當您建立 InputLanguageChangedEventHandler 委派 (Delegate) 時，就可以識別即將處理此事件的方法。 若要使事件與您的事件處理常式產生關聯，請將委派的執行個體 (Instance) 加入至事件。 除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。

如需事件處理常式委派的詳細資訊，請參閱 處理和引發事件。

擴充方法

GetMethodInfo(Delegate)

取得表示特定委派所代表之方法的物件。
