How can I run the PyQt window method MainWindow.load_url() from the main process?
from multiprocessing import Process
import sys
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow
from PyQt5.QtCore import *
from PyQt5.QtWebKitWidgets import *
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.desktop_size = QtWidgets.QDesktopWidget().screenGeometry()
self.__browser = QWebView(self)
# todo
self.init_ui()
def init_ui(self):
self.__browser.resize(self.desktop_size.width(), self.desktop_size.height())
self.load_url('https://stackoverflow.com/')
self.showFullScreen()
def load_url(self, url: str):
self.__browser.load(QUrl(url))
def run_qt():
app = QtWidgets.QApplication(sys.argv)
x = MainWindow()
sys.exit(app.exec_())
class QtGui:
process = None
@staticmethod
def read_process():
if QtGui.process is None:
QtGui.process = Process(target=run_qt)
return QtGui.process
@staticmethod
def stop_process():
if QtGui.process is not None:
if QtGui.process.is_alive():
QtGui.process.terminate()
QtGui.process = None
@staticmethod
def start_process():
if QtGui.read_process().is_alive() is False:
QtGui.read_process().start()
if __name__ == '__main__':
qtGui = QtGui()
qtGui.start_process()

how to run method MainWindow.load_url() from here

I tried to create an instance of QWebKit in the main process and pass it as an argument to have access to it in two processes, but PyQt does not accept it, which I understand. Unfortunately I don't know how I can do it. Thanks
