带有 Flask 的 PyQt 不显示主窗口

Question

我正在尝试创建一个 gui，运行使用此示例的烧瓶应用程序 https://github.com/onur2677/PyQt-Flask

在这个例子中他们使用 pyqt 4

我正在尝试使用 pyqt 5，所以我做了一些更改

但主窗口同时打开和关闭

这是我的 gui 代码

import sys

from PyQt5 import *
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
import psycopg2
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5 import *

from PyQt5.QtCore import QUrl
from PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtWidgets import QApplication, QMainWindow

from PyQt5.QtCore import QEventLoop
from PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtWidgets import QApplication

PORT = 5000
ROOT_URL = 'http://localhost:{}'.format(PORT)

class FlaskThread(QThread):

    def __init__(self, application):
        QThread.__init__(self)
        self.application = application

    def __del__(self):
        self.wait()

    def run(self):
        self.application.run(port=PORT)

def createGuiFor(application):
    qtapp = QApplication(sys.argv)
    webapp = FlaskThread(application)
    webapp.start()
    qtapp.aboutToQuit.connect(webapp.terminate)
    webview = QWebEngineView()
    webview.load(QUrl(ROOT_URL))
    webview.show()
    webview.setWindowTitle("MyApp")
    webview.setContextMenuPolicy(QtCore.Qt.NoContextMenu)
    return qtapp.exec_()

if __name__ == '__main__':
    from MyWebApp import app
    app = QApplication(sys.argv)
    sys.exit(app.exec_())
    sys.exit(createGuiFor(app))

这是将在 gui

中运行的烧瓶应用程序

from flask import Flask ,render_template
app = Flask(__name__)

@app.route("/")
def hello():
    return render_template("index.html")

if __name__ == "__main__":
    app.run()
