PyQt embed QWebEngineView in Main Window

Question

I'm coming from a tkinter background where everything can be put in a frame.

How can I get my current working codes result (which launches a WebEngine View of a page, google in this instance) to sit inside a main window like shown in the image? Going by the image I want the WebEngine to be housed in the "Green" Box for example.

Working code including all versions used

You have to use a QGridLayout:

import sys

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

url = "https://google.com"

app = QApplication(sys.argv)

w = QMainWindow()

browser = QWebEngineView()
browser.load(QUrl(url))

central_widget = QWidget()
w.setCentralWidget(central_widget)

lay = QGridLayout(central_widget)
lay.addWidget(browser, 0, 0, 2, 1)
lay.addWidget(QTextEdit(), 0, 1)
lay.addWidget(QTextEdit(), 1, 1)

lay.setColumnStretch(0, 1)
lay.setColumnStretch(1, 1)

lay.setRowStretch(0, 1)
lay.setRowStretch(1, 1)

w.show()

sys.exit(app.exec_())
