InputLanguageChangedEventHandler 代理人

定義

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)

範例

以下範例建立一個新事件 Form ，並將事件處理程式附加於該 InputLanguageChanged 事件。 此事件改變 IMEmode 輸入語言切換為日語的時間。

備註

當你建立 InputLanguageChangedEventHandler 代理人時，你就能確定處理事件的方法。 要將事件與你的事件處理器關聯，請將該代理的實例加入事件中。 事件處理程序會在事件發生時被呼叫，除非你移除代理。

欲了解更多關於事件處理代表的資訊，請參閱 「處理與提升事件」。
