Illustrates Text events.

This program puts a TextField object in a Frame object and
registers a TextListener object on the TextField.  Whenever
the text contents of the TextField change, a TextEvent is
generated causing the textValueChanged() method of the
listener object to be invoked.

Code in the method extracts the source of the event from 
the incoming TextEvent object, and uses that information
to get and display the current text contents of the
TextField object.

Tested using JDK1.1.6 under Win95.
