java.lang.Objectjava.util.EventObject
java.awt.AWTEvent
java.awt.event.TextEvent
public class TextEvent
A semantic event which indicates that an object's text changed.
This high-level event is generated by an object (such as a TextComponent)
when its text changes. The event is passed to
every TextListener object which registered to receive such
events using the component's addTextListener method.
The object that implements the TextListener interface gets
this TextEvent when the event occurs. The listener is
spared the details of processing individual mouse movements and key strokes
Instead, it can process a "meaningful" (semantic) event like "text changed".
