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

这个类已被1.4焦点API过时了。 虽然客户端代码仍然可以使用此类，但是强烈建议开发人员使用java.awt.KeyboardFocusManager和java.awt.DefaultKeyboardFocusManager 。

请参阅How to Use the Focus Subsystem ，在Java教程一节，以及Focus Specification以获取更多信息。
