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

直接已知子类：
-
DefaultFocusManager
-
public abstract class FocusManager
- extends DefaultKeyboardFocusManager
从 1.4 focus API 开始，此类已被废弃。虽然客户机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。

该字段已被废弃，不鼓励使用它，因为它的规范与 1.4 focus API 不兼容。当前的 FocusManager 已经不再是 UI 的一个属性。客户端代码必须使用
KeyboardFocusManager.getCurrentKeyboardFocusManager() 来查询当前的 FocusManager。有关更多信息，请参阅 Focus Specification。

-
返回调用线程上下文的当前
KeyboardFocusManager 实例。
-
-
返回：
-
此线程上下文的
KeyboardFocusManager
-
另请参见：
-
setCurrentManager(javax.swing.FocusManager)
setCurrentManager
public static void setCurrentManager(FocusManager aFocusManager)
throws SecurityException
-
设置调用线程上下文的当前
KeyboardFocusManager 实例。如果指定了 null，则使用 DefaultKeyboardFocusManager 的新实例替换当前的 KeyboardFocusManager。
如果安装了 SecurityManager，则必须授予调用线程 AWTPermission "replaceKeyboardFocusManager" 权限才能替换当前的 KeyboardFocusManager。如果未授予该权限，则此方法将抛出 SecurityException，而当前的 KeyboardFocusManager 不会改变。
-
-
参数：
-
aFocusManager - 此线程上下文的新 KeyboardFocusManager
-
抛出：
-
SecurityException - 如果调用线程没有替换当前 KeyboardFocusManager 的权限
