Field Detail

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This field is obsolete, and its use is discouraged since its specification is incompatible with the 1.4 focus APIs.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 using KeyboardFocusManager.getCurrentKeyboardFocusManager(). See the Focus Specification for more information.

public FocusManager()

Method Detail

getCurrentManager

public static FocusManager getCurrentManager()

Returns the current KeyboardFocusManager instance for the calling thread's context.

Returns:

this thread's context's KeyboardFocusManager

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 of DefaultKeyboardFocusManager.

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.

Throws:

SecurityException - if the calling thread does not have permission to replace the current KeyboardFocusManager

public static boolean isFocusManagerEnabled()

Deprecated. As of 1.4, replaced by KeyboardFocusManager.getDefaultFocusTraversalPolicy()

Returns whether the application has invoked disableSwingFocusManager().
