I tried to enhanced this code The code embeds a terminal into a pyqt tab and sends command remotely with a button. I tried to make it so that a new tab with another embedded terminal instance is added when pressing a button. I successfully implemented this but the embedded terminal in the new tab isn't placed inside.
This is the code.

self.embed('xterm')
def embed(self, command, *args):
self.name_session = uuid.uuid4().hex
print ("SESSION {0} ID: {1}".format(self.sess_count,self.name_session))
proc = QtCore.QProcess()
proc.setProgram(command)
proc.setArguments(args)
started, procId = QtCore.QProcess.startDetached(
"xterm", ["-e", "tmux", "new", "-s", self.name_session], "."
)
if not started:
QtWidgets.QMessageBox.critical(
self, 'Command "{}" not started!'.format(command), "Eh")
return
attempts = 0
while attempts < 10:
screen = Wnck.Screen.get_default()
screen.force_update()
# do a bit of sleep, else window is not really found
time.sleep(0.1)
# this is required to ensure that newly mapped window get listed.
while Gdk.events_pending():
Gdk.event_get()
for w in screen.get_windows():
print(attempts, w.get_pid(), procId, w.get_pid() == procId)
if w.get_pid() == procId:
#self.window = QtGui.QWindow.fromWinId(w.get_xid())
proc.setParent(self)
win32w = QtGui.QWindow.fromWinId(w.get_xid())
win32w.setFlags(QtCore.Qt.FramelessWindowHint)
widg = QtWidgets.QWidget.createWindowContainer(win32w)
self.addTab(widg, command)
#self.insertTab(self.sess_count, widg, command)
#widg.setFocusPolicy(QtCore.Qt.StrongFocus)
#self.currentIndex(self.sess_count)
self.resize(500, 400) # set initial size of window
# self.setFocus()
# self.update()
return

class MainWindow(QtWidgets.QMainWindow):

self.ifconfig_btn = QtWidgets.QPushButton("ifconfig")

self.add_term_btn = QtWidgets.QPushButton("add terminal")
self.terminal = Container()
central_widget = QtWidgets.QWidget()
self.setCentralWidget(central_widget)
lay = QtWidgets.QGridLayout(central_widget)
lay.addWidget(self.ifconfig_btn, 0, 0)
lay.addWidget(self.ping_btn, 0, 1)
lay.addWidget(self.add_term_btn, 1, 0, 1, 2)
lay.addWidget(self.terminal, 2, 0, 2, 2)

def launch_ifconfig(self):
self.terminal.send_command("ifconfig")
def launch_ping(self):
self.terminal.send_command("ping 8.8.8.8")
def closeEvent(self, event):
self.terminal.stop()
super().closeEvent(event)
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
Also, I found a workaround to fix this, Video Link on the workaround, but as you can see, it involves interacting the GUI, not by code. I want to fix this via code.
When clicking the Add Terminal Button, the embedded terminal should be inside the new tab.
