Class DefaultFocusManager

java.lang.Object

java.awt.KeyboardFocusManager

java.awt.DefaultKeyboardFocusManager

javax.swing.FocusManager

javax.swing.DefaultFocusManager

All Implemented Interfaces:

KeyEventDispatcher， KeyEventPostProcessor

public class DefaultFocusManager
extends FocusManager

这类被淘汰的1.4个焦点的API。而客户端的代码仍然可以使用这个类，开发商强烈鼓励使用 java.awt.KeyboardFocusManager和 java.awt.DefaultKeyboardFocusManager相反。

请看 How to Use the Focus Subsystem，java教程中的一部分，和更多的信息Focus Specification。
