FocusManager (Java Platform SE 6) (original) (raw)
javax.swing
Class FocusManager
java.lang.Object
java.awt.KeyboardFocusManager
java.awt.DefaultKeyboardFocusManager
javax.swing.FocusManager
All Implemented Interfaces:
KeyEventDispatcher, KeyEventPostProcessor
Direct Known Subclasses:
public abstract class FocusManager
extends DefaultKeyboardFocusManager
This class has been obsoleted by the 1.4 focus APIs. While client code may still use this class, developers are strongly encouraged to usejava.awt.KeyboardFocusManager andjava.awt.DefaultKeyboardFocusManager instead.
Please see How to Use the Focus Subsystem, a section in The Java Tutorial, and theFocus Specification for more information.

FOCUS_MANAGER_CLASS_PROPERTY
public static final String FOCUS_MANAGER_CLASS_PROPERTY
This field is obsolete, and its use is discouraged since its specification is incompatible with the 1.4 focus APIs. The current FocusManager is no longer a property of the UI. Client code must query for the current FocusManager usingKeyboardFocusManager.getCurrentKeyboardFocusManager(). See the Focus Specification for more information.

getCurrentManager
public static FocusManager getCurrentManager()
Returns the current KeyboardFocusManager instance for the calling thread's context.
Returns:
this thread's context's KeyboardFocusManager
See Also:
setCurrentManager(javax.swing.FocusManager)
setCurrentManager
public static void setCurrentManager(FocusManager aFocusManager) throws SecurityException
Sets the current KeyboardFocusManager instance for the calling thread's context. If null is specified, then the current KeyboardFocusManager is replaced with a new instance ofDefaultKeyboardFocusManager.
If a SecurityManager is installed, the calling thread must be granted the AWTPermission "replaceKeyboardFocusManager" in order to replace the the current KeyboardFocusManager. If this permission is not granted, this method will throw a SecurityException, and the current KeyboardFocusManager will be unchanged.
Parameters:
aFocusManager - the new KeyboardFocusManager for this thread's context
Throws:
[SecurityException](../../java/lang/SecurityException.html "class in java.lang") - if the calling thread does not have permission to replace the current KeyboardFocusManager

getCurrentManager(), DefaultKeyboardFocusManager
disableSwingFocusManager
@Deprecated public static void disableSwingFocusManager()
Deprecated. as of 1.4, replaced by KeyboardFocusManager.setDefaultFocusTraversalPolicy(FocusTraversalPolicy)
Changes the current KeyboardFocusManager's defaultFocusTraversalPolicy toDefaultFocusTraversalPolicy.
See Also:
DefaultFocusTraversalPolicy, KeyboardFocusManager.setDefaultFocusTraversalPolicy(java.awt.FocusTraversalPolicy)
isFocusManagerEnabled
@Deprecated public static boolean isFocusManagerEnabled()
Deprecated. As of 1.4, replaced byKeyboardFocusManager.getDefaultFocusTraversalPolicy()
Returns whether the application has invokeddisableSwingFocusManager().
