from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
import sys

class Browser(QWebEngineView):
    def __init__(self):
        super(QWebEngineView, self).__init__()
        self.page = self.page()
        self.setFixedSize(720, 760)
        self.load(QUrl("https://www.baidu.com/baidu?wd=QQ&tn=monline_4_dg&ie=utf-8"))


if __name__ == '__main__':
