[Python] PyQt Threads

 Define the Thread:

class ThreadWorker(QThread):
    updateValueSignal = pyqtSignal(str)
    updateTextEditSignal = pyqtSignal(str)

    def run(self):

        #self.updateTextEditSignal.emit("Started MODBUS Read...\r\n\r\n")

        self.updateTextEditSignal.emit("emit text signal")
        print("emit text signal")

        #buttonReply = QMessageBox.question(self, 'READ PASS', f"Reading from {modbus_ip} > Serial no.: {regs[0]}",
        #                                   QMessageBox.Ok)

    def stop(self):
        self.terminate()

Running the thread:

def RunThread(self):
    self.threadworker = ThreadWorker()
    #self.threadworker.updateValueSignal.connect(self.showdialog)
    self.threadworker.updateTextEditSignal.connect(self.updateText)
    # self.modbusworker.updateListSignal.connect(self.updateList)
    self.threadworker.start()
