java.lang.Object java.awt.KeyboardFocusManager java.awt.DefaultKeyboardFocusManager javax.swing.FocusManager
public abstract class FocusManager
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。

public static FocusManager getCurrentManager()
KeyboardFocusManager
实例。
KeyboardFocusManager
setCurrentManager(javax.swing.FocusManager)
public static void setCurrentManager(FocusManager aFocusManager) throws SecurityException
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。
aFocusManager
- 此线程上下文的新 KeyboardFocusManager

- 如果调用线程没有替换当前 KeyboardFocusManager
的权限getCurrentManager()
,
DefaultKeyboardFocusManager
@Deprecated public static void disableSwingFocusManager()
KeyboardFocusManager.setDefaultFocusTraversalPolicy(FocusTraversalPolicy)
取代
KeyboardFocusManager
的默认 FocusTraversalPolicy
更改为 DefaultFocusTraversalPolicy
。
DefaultFocusTraversalPolicy
,
KeyboardFocusManager.setDefaultFocusTraversalPolicy(java.awt.FocusTraversalPolicy)
@Deprecated public static boolean isFocusManagerEnabled()
KeyboardFocusManager.getDefaultFocusTraversalPolicy()
取代
disableSwingFocusManager()
。
