InputLanguageChangedEventHandler 委托

表示将要处理 Form 的 InputLanguageChanged 事件的方法。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Delegate Sub InputLanguageChangedEventHandler ( _
    sender As Object, _
    e As InputLanguageChangedEventArgs _
)
用法
Dim instance As New InputLanguageChangedEventHandler(AddressOf HandlerMethod)

public delegate void InputLanguageChangedEventHandler (
    Object sender,
    InputLanguageChangedEventArgs e
)

public delegate void InputLanguageChangedEventHandler (
    Object^ sender, 
    InputLanguageChangedEventArgs^ e
)

/** @delegate */
public delegate void InputLanguageChangedEventHandler (
    Object sender, 
    InputLanguageChangedEventArgs e
)

JScript 支持使用委托，但不支持进行新的声明。

参数

• sender
  事件源。

• e
  包含事件数据的 InputLanguageChangedEventArgs。

备注

创建 InputLanguageChangedEventHandler 委托时，标识将处理事件的方法。若要使该事件与事件处理程序相关联，请将该委托的一个实例添加到事件中。除非移除了该委托，否则每当发生该事件时就调用事件处理程序。

有关事件处理程序委托的更多信息，请参见 事件和委托。

示例

下面的示例创建一个新的 Form，并将一个事件处理程序连接到 InputLanguageChanged 事件。当输入语言更改成日语时，此事件更改 IMEmode。
