QT PySide 连连看小游戏

学了PySide，花了一天时间做出了以前很想写的一个游戏，然后写完主体的逻辑之后就不想再接着往下写了。

在windows下写的

6*6的方格，总共6种图像，网上找的6张gif图片，然后把大小用windows的画图变成50*50像素的图像，这是点击之前的图像。然后把gif图中白色的像素涂黑变成点击之后的图像（这个也是用windows画图解决的）。刚接触python，感觉格式会很好，但是self这个有点不爽的。

myvis[i][j] 表示（i，j）这个点是未点击的，点击过的，还是空白

mymap[i][j] 这个点应该显示何种图像

InitBoard 初始化连连看的地图

图像的绘制交给paintEvent

在鼠标点击的时候，检查两个点之后是否可以连接首先检查两个点的图像是不是相同的，然后检查是不是经过至多三条线段就能到达（这个我是用ＤＦＳ（深度优先搜索）的，深搜的代价有点大，可以用ＢＦＳ（宽度优先搜索）来优化，但是由于我不想接着写下去，就没有优化了）。

写的很粗糙，只是练习用。
