jcframe.java

这是自己在学习编写下象棋时参考过的很好的程序。

 * jcFrame.java - GUI for JavaChess

 * Purpose: Sometime in the very distant future, I may graft a true GUI onto
 * this game (i.e., drag-and-drop pieces to move, etc.)  In the meantime, this
 * class will only contain the absolute bare minimum functionality required
 * by Java: an empty window with a "close box" allowing quick exit.
