# 腾讯视频热播列表
|
||||
|
||||
简单思路说明：
|
||||
|
||||
- 利用QScrollArea滚动显示，QGridLayout或者FlowLayout做布局来放置自定义的Widget
|
||||
- QNetworkAccessManager异步下载网页和图片
|
||||
- QScrollArea滚动到底部触发下一页加载
|
||||
|
||||
自定义控件说明：
|
||||
|
||||
- 主要是多个layout和控件的结合，其中图片QLabel为自定义，通过setPixmap设置图片，重写paintEvent绘制底部渐变矩形框和白色文字
|
||||
- 字体颜色用qss设置
|
||||
- 图标利用了QSvgWidget显示，可以是svg 动画（如圆形加载图）
|
||||
