项目实战：Qt5／C++：QT象棋【初版】
编辑环境：win10_x64 ／Qt5.4.1
项目:Qt 象棋
[2]双人模式(单PC端)的功能，但是后面的功能是在这些基础上面，直接进行一些人工智能，电脑根据玩家的下法，通过指定的规则，来进行可能得算法，从而下一些可能是的的算法步骤。而最后的socket的双人PC端进行游戏，在现在现在基础上面加上Socket编程的类就可以了。
其他：后续还是会继续更新的，当有空的时候是会继续完善后面的功能的。

项目运行效果
==================================================================
==================================================================
项目思路分析：
==================================================================
步骤：
1.绘画棋盘
2.绘画棋子
3.棋盘行列值和屏幕之间的像素值之间进行切换
4.象棋轮流下
5.制定象棋的具体规则
6.屏幕重绘
