public class TextEvent extends AWTEvent
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".
An unspecified behavior will be caused if the id parameter
of any particular TextEvent instance is not
in the range from TEXT_FIRST to TEXT_LAST.
