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 use java.awt.KeyboardFocusManager
and java.awt.DefaultKeyboardFocusManager
instead.
Please see How to Use the Focus Subsystem, a section in The Java Tutorial, and the Focus Specification for more information.
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This field is obsolete, and its use is discouraged since its specification is incompatible with the 1.4 focus APIs.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.
