Class BasicComboBoxUI.KeyHandler

java.lang.Object
java.awt.event.KeyAdapter
javax.swing.plaf.basic.BasicComboBoxUI.KeyHandler
All Implemented Interfaces:
KeyListener, EventListener
Enclosing class:
BasicComboBoxUI
public class BasicComboBoxUI.KeyHandler extends KeyAdapter
This listener checks to see if the key event isn't a navigation key. If it finds a key event that wasn't a navigation key it dispatches it to JComboBox.selectWithKeyChar() so that it can do type-ahead. This public inner class should be treated as protected. Instantiate it only within subclasses of BasicComboBoxUI.
