PyQt5如何實現多張圖片顯示并滾動

這篇文章主要為大家展示了“PyQt5如何實現多張圖片顯示并滾動”，內容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領大家一起研究并學習一下“PyQt5如何實現多張圖片顯示并滾動”這篇文章吧。

單頁面顯示多張圖片

習慣性的用GridLayout但是發現怎么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，后面網上借鑒了一下用了ScrollArea實現了

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)


if __name__ == '__main__':
    app = QApplication(sys.argv)

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

效果如下：

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。
