用qt做了一个王者荣耀皮肤抽奖器，效果如下图。

说一下过程吧，第一步，就是先准备好皮肤的图片，皮肤的图片在王者荣耀的官网是可以下载的，但是过百的下载量确实有点大了，动了个小心思，网上找了一个用py写的爬虫，用来爬了官网的图片。下载地址

将下载好的图片进行分类，这真是在考验我的耐心，对于一个完全对皮肤没认识的来说太艰难了，还好有我三位王者室友的帮助！，很快的对皮肤进行了分类，有288的，有488的，等等。

---

然后就是qt代码啦，其实代码并不多。

没加载背景的样子，好丑（这不是重点）。

---

思路就是mainwindow.h头文件下面放的都是皮肤对应的名字。将他们放在字符串数组中，对字符串下标进行随机抽取，然后通过加载字符串加载对应的图片（图片放在资源下面）。

mianwindow.cpp 要说的可能就是概率，我本来是想100里面随机到0-20算20%，后来发现这样根本不准，我要是商家我就亏大了，我把100换成了较大的数，这个概率数据才能算是正确的。
