BasicComboBoxUI.KeyHandler (Java SE 9 & JDK 9 )

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.
