一般用 QLabel 控件来存放图片，但是图片有大有小，比例也不一样，如何才能让它自适应控件大小呢？本文来实践一下。
使用工具 designer，新建一个窗口，然后拖动一个 label 到窗口中，接着，空白处右键点击 布局 --> 栅格布局
保存成 ui 文件后，使用 pyuic 将其转化成 python 代码
pyuic5.bat -o ui.py project.ui完整的代码如下
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication
from PyQt5.QtGui import QPixmap
from ui import Ui_MainWindow
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
pix = QPixmap('wechat.jpg')
# 自适应
self.label.setScaledContents(True)
self.label.setPixmap(pix)
if __name__ == '__main__':
app = QApplication(sys.argv)
windows = MainWindow()
windows.show()
sys.exit(app.exec_())
执行上述代码
