一.前言
本次将之前做的和新做的轮播图Demo进行展示。废话不多说,直接上图
二.展示
1.酷我音乐
数据源:网络
格式:接口Json
参考网站:http://www.kuwo.cn/
支持自动、手动切换,导航栏切换图片
2.QQ飞车
数据源:网络
格式:接口Json
参考网站:数据来源QQ飞车客户端抓包
官网:http://speed.qq.com/main.shtml
支持自动、手动切换,导航栏切换图片(右上角那个不规则按钮还不能实现)
3.虎牙
数据源:网络
格式:接口Json
参考网站:https://www.huya.com/
支持自动、手动切换,导航栏、左右按钮切换图片
4.网易云音乐
数据源:本地
格式:列表
参考网站:https://music.163.com/
支持自动、手动切换,导航栏、左右按钮切换图片,轮播图切换动画为淡出
5.英雄联盟
数据源:本地
格式:列表
参考网站:https://lol.qq.com/main.shtml
支持自动、手动切换,导航栏切换图片,轮播图切换动画为正弦缓入
6.英雄联盟(Pro)
在上一个的基础上进行改进,重写QStackWidget的SetCurrentInex()函数,实现了过渡动画的显示
7.腾讯视频
数据源:本地
格式:列表
参考网站:https://v.qq.com/
这个上了点难度,不过只要慢慢拆解,还是不难的。
支持自动、手动切换,导航栏切换图片,支持手动切换推荐视频
值得一提的是,“猜你会追”页面有个子页面,里面是一些电影、电视剧推荐,要通过按钮手动切换推荐,鼠标放在推荐上,封面会自动放大(注意“下一张”按钮位置)。
动图被压缩了,可能看不太清,贴一张静图。
三.源代码
贴一下demo3的代码

五.总结
本次展示了几个使用PyQt5开发的轮播图,重点在于如何美观地展示图片数据,上面的示例中,前三个的数据都是通过网络获取地,后面三个的数据是在本地读取的。思路、代码方面有什么不足欢迎各位大佬指正、批评!觉得还行,能点个赞吗?
