Error "Parameter 'url' unfilled" using PyQt5 with url set

Question

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

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.browser = QWebEngineView
        self.browser.setUrl(QUrl("http://google.com"))
        self.setCentralWidget(self.browser)
        self.showMaximized()

app = QApplication(sys.argv)
QApplication.setApplicationName('Browser')
window = MainWindow
app.exec_()

This is so far my code, but it gives me an error at the Url line although i've set google.com

Answer 1

You forgot the parenthesis after MainWindow when calling the class at the end, as well as you need to add window.show(). You also need to specify to QWebEngineView an argument (in this case self).

So adding those things the code would look like this:

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

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.browser = QWebEngineView(self)
        self.browser.setUrl(QUrl("http://google.com"))
        self.setCentralWidget(self.browser)
        self.showMaximized()

app = QApplication(sys.argv)
QApplication.setApplicationName('Browser')
window = MainWindow()
window.show()
app.exec_()

Tell me if it doesn't work for you.
