PyQt5: Looking for example of Embedding external app window in Application

Question

I have a largeish application I'm developing in Python3 using PyQt5. I want to do something very much like what is being done here in PyQt4:

# -*- coding: utf-8 -*-
import atexit

from PyQt4.QtCore import *
from PyQt4.QtGui import *


class XTerm(QX11EmbedContainer):

    def __init__(self, parent, xterm_cmd="xterm"):
        QX11EmbedContainer.__init__(self, parent)
        self.xterm_cmd = xterm_cmd
        self.process = QProcess(self)
        self.connect(self.process,
                     SIGNAL("finished(int, QProcess::ExitStatus)"),
                     self.on_term_close)
        atexit.register(self.kill)

    def kill(self):
        self.process.kill()
        self.process.waitForFinished()

    def sizeHint(self):
        size = QSize(400, 300)
        return size.expandedTo(QApplication.globalStrut())

    def show_term(self):
        args = [
            "-into",
            str(self.winId()),
            "-bg",
            "#000000",  # self.palette().color(QPalette.Background).name(),
            "-fg",
            "#f0f0f0",  # self.palette().color(QPalette.Foreground).name(),
            # border
            "-b", "0",
            "-w", "0",
            # blink cursor
            "-bc",
        ]
        self.process.start(self.xterm_cmd, args)
        if self.process.error() == QProcess.FailedToStart:
            print "xterm not installed"

    def on_term_close(self, exit_code, exit_status):
        print "close", exit_code, exit_status
        self.close()

(from https://bitbucket.org/henning/pyqtwi...11/terminal.py)

• which is: Embed an X11 shell terminal (xterm) into a tab of my application.

I understand that QX11EmbedContainer is not in PyQt5, and that some usage of createWindowContainer may be the new approach, but I cannot find any example of this in action to follow.

I would ideally like to see the above code ported to a fully functional example using PyQt5 conventions and methods, but any assistance in any form will be helpful.

I have looked at Embedding external program inside pyqt5, but there is only a win32 solution there, and I need to run on Linux and MacOS, with windows being an unnecessary nicety, if there was a generalized solution to fit all 3. It feels like this is close, but I cannot find the appropriate replacement for the win32gui module to use in a general implementation.

I have looked at example of embedding matplotlib in PyQt5 1, but that pertains to matplotlib in particular, and not the general case.

All pointers and help will be gratefully acknowledged.
