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，本文就来介绍一下

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) if __name__ == '__main__': app = QApplication(sys.argv) url=['https://pic2.zhimg.com/aadd7b895_xs.jpg-600?source=1940ef5c', 'https://pic2.zhimg.com/50/v2-60f7b5c071d378a34a3a6c489c3fdacc_hd.jpg-600?source=1940ef5c', 'https://pic2.zhimg.com/80/v2-60f7b5c071d378a34a3a6c489c3fdacc_720w.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-aa7d74fe48183d16a571278a012ff759_hd.jpg-600?source=1940ef5c', 'https://pic4.zhimg.com/50/v2-011ac12cbfe61ebc411ba437fac88780_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-dea9876e70b0a0b08b635796eb2c86da_hd.jpg-600?source=1940ef5c', 'https://pic2.zhimg.com/50/v2-8574116f58ac5e560da7e3656f80dcdf_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/80/v2-10e18ff65a640175ad058b4b5dfd2867_1440w.png-600', 'https://picb.zhimg.com/80/v2-a448b133c0201b59631ccfa93cb650f3_1440w.png-600', 'https://pic2.zhimg.com/v2-0cd41264be96353da10f5aca4088aa37_xs.jpg-600?source=1940ef5c', 'https://pic2.zhimg.com/50/v2-74c0b99f286ef52fefe4fd0cbe78c90b_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-27b377ed5db6b090a9834b00ffe54b8e_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-c7c874b8540a5dbdd93418429c39f188_hd.jpg-600?source=1940ef5c', 'https://pic4.zhimg.com/50/v2-fef58d7f36acb12ff4199fa507fc166e_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-fcd8d49f62634cb631ac08d5d1cc11ea_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-74fe1b6d5362b73fcfe5b887afcad6eb_hd.jpg-600?source=1940ef5c', 'https://pic2.zhimg.com/50/v2-6b6213d9a94f57722642b6bed847c6a2_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-bad7183c3135ea26d2e8e52653ee1f1c_hd.jpg-600?source=1940ef5c', 'https://pic2.zhimg.com/50/v2-476f50c384e1a4c90e994e6d63f63e8a_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-d720e9f8984d83da0a7344fa842cafa1_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-e82f6e26e7b49d7d7a5a0a337e2cd613_hd.jpg-600?source=1940ef5c', 'https://pic4.zhimg.com/50/v2-25496d917bf08c0ebc5106bb91f376a5_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-36e309f84b1395933488e6fa0f6bd341_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/80/v2-10e18ff65a640175ad058b4b5dfd2867_1440w.png-600', 'https://picb.zhimg.com/80/v2-a448b133c0201b59631ccfa93cb650f3_1440w.png-600', 'https://pic3.zhimg.com/aadd7b895_xs.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-c673663f10a662afc4a09dfe0d95c62c_hd.jpg-600?source=1940ef5c', 'https://pic4.zhimg.com/50/v2-891dd82d13e152e6204a827362adb0ef_hd.jpg-600?source=1940ef5c', 'https://pic3.zhimg.com/50/v2-dba8ca86ac6aa7c8517d22ee983c6e05_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/50/v2-f16d5a24150db2816817fa698ac4ad82_hd.jpg-600?source=1940ef5c', 'https://pic1.zhimg.com/80/v2-10e18ff65a640175ad058b4b5dfd2867_1440w.png-600', 'https://picb.zhimg.com/80/v2-a448b133c0201b59631ccfa93cb650f3_1440w.png-600', 'https://static.zhihu.com/heifetz/assets/sidebar-download-qrcode.7caef4dd.png-600', 'https://pic1.zhimg.com/70/v2-8228fff23c22a72b57d1627b7213942c.jpg-600', 'https://pic2.zhimg.com/aadd7b895_im.jpg-600?source=1940ef5c', 'https://pic3.zhimg.com/90/v2-426097a9370aad0ab673d53cca060c93_250x0.jpg-600', 'https://pic2.zhimg.com/90/v2-18b57487b9aca2b8e12246f67be0d138_250x0.jpg-600', 'https://pic2.zhimg.com/90/v2-50f7c79c972342024947936b0420b8e4_250x0.jpg-600', 'https://pic4.zhimg.com/v2-1945b21d09872d21de3db9c9614918b3_540x450.jpeg', 'https://pic3.zhimg.com/80/v2-d0289dc0a46fc5b15b3363ffa78cf6c7.png-600'] pic = Picture(url=url) pic.show() sys.exit(app.exec_())
