How To Embed Terminal Inside PyQt5 Application Without QProcess?

I have been struggling lately with embedding a terminal inside PyQt GUI app. Tried almost every search on Internet but nothing looks like of any help. I have a QTabWidget and I si

Solution 1:

short answer: Qt5 does not provide the use of the terminal, so you will have to use QProcess.

TL;DR

The EmbTerminal class that is proposed as a solution is a widget so you must add it with addTab(), keep in mind that you must have installed the urxvt terminal (if you want to check your installation run urxvt in the terminal)

import sys
from PyQt5 import QtCore, QtWidgets


class EmbTerminal(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super(EmbTerminal, self).__init__(parent)
        self.process = QtCore.QProcess(self)
        self.terminal = QtWidgets.QWidget(self)
        layout = QtWidgets.QVBoxLayout(self)
        layout.addWidget(self.terminal)
        # Works also with urxvt:
        self.process.start('urxvt',['-embed', str(int(self.winId()))])
        self.setFixedSize(640, 480)


class mainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(mainWindow, self).__init__(parent)

        central_widget = QtWidgets.QWidget()
        lay = QtWidgets.QVBoxLayout(central_widget)
        self.setCentralWidget(central_widget)

        tab_widget = QtWidgets.QTabWidget()
        lay.addWidget(tab_widget)

        tab_widget.addTab(EmbTerminal(), "EmbTerminal")
        tab_widget.addTab(QtWidgets.QTextEdit(), "QTextEdit")
        tab_widget.addTab(QtWidgets.QMdiArea(), "QMdiArea")


if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    main = mainWindow()
    main.show()
    sys.exit(app.exec_())
