public class TimedKeySelectionManager

extends java.lang.Object

implements javax.swing.JComboBox.KeySelectionManager

A JComboBox KeySelectionManager subclass that can be attached to a JComboBox to allow typing multiple characters of an item name to find it within the JComboBox's model. That is, rather than only keying on the first character in the item's name, TimedKeySelectionManager allows a user to type the full name of an object to select it, as long as the user doesn't hesitate for more than half a second between keystrokes.
