javax.swing
类 DefaultFocusManager

java.lang.Object
  java.awt.KeyboardFocusManager
      java.awt.DefaultKeyboardFocusManager
          javax.swing.FocusManager
              javax.swing.DefaultFocusManager

所有已实现的接口：: KeyEventDispatcher, KeyEventPostProcessor

public class DefaultFocusManager
extends FocusManager

此类已被废弃，用 1.4 focus API 取代。虽然客户端代码可能仍然使用此类，但强烈建议开发人员使用 java.awt.KeyboardFocusManager 和 java.awt.DefaultKeyboardFocusManager 替代。

有关更多信息，请参阅 The Java Tutorial 中的 How to Use the Focus Subsystem 一节和 Focus Specification。
