显示图片并缩放

import requests

def show_image(self):
    rep = requests.get(self.url)
    image = QPixmap()
    image.loadFromData(req.content)
    self.piclabel.setPixmap(image.scaled(self.width, self.height))

查找子部件

self.findChild(QLabel,'objectname')

固定窗口大小

self.setFixedSize(w,h)
self.setFixedHeight(h)
self.setFixedWidth(w)
