What this is

This file is part of the Tame Swing collection that we have compiled. All of the Java source code in these examples was created by Nobuo Tamemasa. As these examples have become hard to find on the internet, we have put them in one place here, supported by minimal advertising. In time we will include images of each running sample Java/Swing application.

The intent of having these files here is to help you learn Java and Swing by example, and Tame certainly created some terrific examples of the power of the Swing framework.
