FocusManager (Java SE 15 & JDK 15) (original) (raw)

All Implemented Interfaces:

[KeyEventDispatcher](../../java/awt/KeyEventDispatcher.html "interface in java.awt"), [KeyEventPostProcessor](../../java/awt/KeyEventPostProcessor.html "interface in java.awt")

Direct Known Subclasses:

[DefaultFocusManager](DefaultFocusManager.html "class in javax.swing")

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.

Since:

1.2

• Field Details

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  This field is obsolete, and its use is discouraged since its specification is incompatible with the 1.4 focus APIs.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

  public FocusManager()

• Method Details

  • 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

  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.base/java/lang/SecurityException.html "class in java.lang") - if the calling thread does not have permission to replace the current KeyboardFocusManager

  • disableSwingFocusManager

  @Deprecated public static void disableSwingFocusManager()
  Changes the current KeyboardFocusManager's defaultFocusTraversalPolicy toDefaultFocusTraversalPolicy.

  • isFocusManagerEnabled

  @Deprecated public static boolean isFocusManagerEnabled()
  Returns whether the application has invokeddisableSwingFocusManager().
  Returns:
  true if focus manager is enabled.
