【Python项目】配合爱漫画爬取漫画脚本而设计的GUI漫画阅读器 (一)

博客园的第一个坑,想想都有点小激动 =3=

 

首先是那个爬虫的地址:

【原创】最近写的一个比较hack的小爬虫

 

选择工具:

以前用过Qt,那么选pyqt4也就是情理之中了。

 

明确需求:

0、首先,要读取漫画的全部章节进来,同时能选择相应的章节。

1、其次,进入相应的章节后,显示该章节的图片,同时有“下一页”、“上一页”、“返回主界面”等基本功能

3、最后,最好能有书签功能。程序应该能够根据章节和页码的信息定位相应的图片

 

最后是还没有来得及实现书签的代码:

 应该加入个临时书签的功能,也就是退出后,如果是章节B页面13,那么下次再进入程序时也是章节B页面13
