This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences.

AWTEventMulticaster, BasicButtonListener, BasicComboBoxEditor, BasicComboBoxEditor.UIResource, MetalComboBoxEditor, MetalComboBoxEditor.UIResource, BasicComboBoxUI.FocusHandler, BasicListUI.FocusHandler, BasicSliderUI.FocusHandler, BasicTableUI.FocusHandler, BasicToolBarUI.ToolBarFocusListener, BasicTreeUI.FocusHandler, Component.AccessibleAWTComponent.AccessibleAWTFocusHandler, DefaultCaret, BasicTextUI.BasicCaret, FocusAdapter, BasicSplitPaneUI.FocusHandler, BasicTabbedPaneUI.FocusHandler, JComponent.AccessibleJComponent.AccessibleFocusHandler
public interface FocusListener
extends EventListener

The listener interface for receiving keyboard focus events on a component. The class that is interested in processing a focus event either implements this interface (and all the methods it contains) or extends the abstract FocusAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with a component using the component's addFocusListener method. When the component gains or loses the keyboard focus, the relevant method in the listener object is invoked, and the FocusEvent is passed to it.

Method Summary
 void
focusGained(FocusEvent e)

          Invoked when a component gains the keyboard focus.
 void
focusLost(FocusEvent e)

          Invoked when a component loses the keyboard focus.
