PyQt5实现多张图片显示并滚动

最近要做个网页图片批量下载工具，然后需要一个页面显示网页上的所有图片供用户勾选，再根据勾选的内容来下载指定图片，其中就涉及到要到同时显示多张图片。

单页面显示多张图片

习惯性的用GridLayout但是发现怎么长时间解决都无法实现滚动，这样就会强制压缩图片大小，导致图片较多时显示的图片太小，不是我想要的，后面网上借鉴了一下用了ScrollArea实现了

代码如下：

import sys
import requests
from PyQt5.QtWidgets import (QWidget,  QLabel,QVBoxLayout,QCheckBox,QGridLayout, QScrollArea,QApplication)
from PyQt5.QtGui import  QPixmap
from PyQt5.QtCore import Qt,QSize

class Picture(QWidget):
    def __init__(self, parent=None, url=None):
        super().__init__(parent)
        self.url = url
        self.ui()

    def ui(self):
        self.setFixedSize(850,600)
        layout = QGridLayout()
        total = len(self.url)
        self.setLayout(layout)
        self.sc = QScrollArea(self)
        self.qw = QWidget()
        if total % 5 == 0:
            rows = int(total/5)
        else:
            rows = int(total/5) + 1
        self.qw.setMinimumSize(850,230*rows)
        for i in  range(total):
            pre_url = self.url[i].split("?")[0]
            sup = pre_url.split(".")[-1]
            req = requests.get(self.url[i])
            photo = QPixmap()
            photo.loadFromData(req.content)
            width = photo.width()
            height = photo.height()
            if width==0 or height==0:
                continue
            tmp_image = photo.toImage()
            size = QSize(width,height)
            photo.convertFromImage(tmp_image.scaled(size, Qt.IgnoreAspectRatio))
            tmp = QWidget(self.qw)
            vl = QVBoxLayout()
            label= QLabel()
            label.setFixedSize(150,200)
            label.setStyleSheet("border:1px solid gray")
            label.setPixmap(photo)
            label.setScaledContents(True)
            ck = QCheckBox(str(i)+"."+sup+"("+str(width)+"x"+str(height)+")", self)
            vl.addWidget(label)
            vl.addWidget(ck)
            tmp.setLayout(vl)
            tmp.move(160 * (i % 5), 230 * int(i / 5))
        self.sc.setWidget(self.qw)

    pic = Picture(url=url)
    pic.show()
    sys.exit(app.exec_())

效果如下：

其中要计算好QWdiget的高度才能滚动，不然会发现可滚动的不足导致部分看不到或者滚动太多导致部分空白，都不好看。
