PyQt5實現多張圖片顯示並滾動

最近要做個網頁圖片批量下載工具,然後需要一個頁面顯示網頁上的所有圖片供用戶勾選,再根據勾選的內容來下載指定圖片,其中就涉及到要到同時顯示多張圖片。

單頁面顯示多張圖片

習慣性的用GridLayout但是發現怎麼長時間解決都無法實現滾動,這樣就會強制壓縮圖片大小,導致圖片較多時顯示的圖片太小,不是我想要的,後面網上借鑒瞭一下用瞭ScrollArea實現瞭

代碼如下:

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:

在這裡插入圖片描述

其中要計算好QWdiget的高度才能滾動,不然會發現可滾動的不足導致部分看不到或者滾動太多導致部分空白,都不好看。
