Java javax.swing Class FocusManager（JDK8）

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  This field is obsolete, and its use is discouraged since its specification is incompatible with the 1.4 focus APIs.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.
