[Tkinter] Updating Tkinter label using multiprocessing

[Gribouillis]

The object c_queue is not callable. Try this perhaps

    def CheckQueuePoll(self, c_queue):
        try:
            str = c_queue.get_nowait()
            c_queue.task_done()
            self.currentUserProcess2.configure(text=str)
        except queue.Empty:
            pass
        finally:
            self.root.after(100, self.CheckQueuePoll, q)
