# QListView
## 1、腾讯视频热播列表
[运行](HotPlaylist.py)
简单思路说明:
- 利用`QScrollArea`滚动显示,自定义的`QFlowLayout`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)

# 截图
使用QGridLayout 固定列数效果图
![截图1](ScreenShot/1.gif)
使用自定义布局FlowLayout 自动列数效果图
![截图2](ScreenShot/2.gif)
使用QListWidget 配合setFlow(QListWidget.LeftToRight)和
setWrapping(True)和
setResizeMode(QListWidget.Adjust)达到类似FlowLayout的效果

简单思路说明:
- 利用`QListWidget`设置一些特殊的参数达到可以横向自动显示
- `QNetworkAccessManager`异步下载网页和图片
- 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)
`QListWidget`的参数设置
1. `setFlow(QListWidget.LeftToRight)`
2. `setWrapping(True)`
3. `setResizeMode(QListWidget.Adjust)`
