[Tkinter] Updating Tkinter label using multiprocessing

[Agusms]

Hi!
I'm having trouble updating a label depending on a result from a function from one of the two processes I'm running. I'm trying using Queues, but can't make it work.

This is a simplified example of the code:

import multiprocessing as mp
from tkinter import DISABLED, NORMAL, Label, LabelFrame, Tk
import queue

class Gui(object):
    def __init__(self, q):
        self.root = Tk()
        self.root.geometry('150x100')

        self.frameP1 = LabelFrame(self.root, text="Process1", font=("Helvetica", 14, "bold"), bd=0)
        self.frameP1.pack(padx=12)
        self.currentUserProcess1 = Label(self.frameP1, text="Current User p1", font=("Helvetica", 10, "bold"))
        self.currentUserProcess1.pack()
        
        self.frameP2 = LabelFrame(self.root, text="Process2", font=("Helvetica", 14, "bold"), bd=0)
        self.frameP2.pack()
        self.currentUserProcess2 = Label(self.frameP2, text="Current User p2", font=("Helvetica", 10, "bold"))
        self.currentUserProcess2.pack()
        self.root.after(100,self.CheckQueuePoll,q)
    

    def CheckQueuePoll(self, c_queue):
        try:
            str = c_queue(0)
            self.currentUserProcess2.configure(text=str)
        except queue.Empty:
            pass
        finally:
            self.root.after(100, self.CheckQueuePoll, q)

def process1():
    print("Executing process1")
    
    #doSomething

def process2():
    print("Executing process2")
    log = "Current User Process 2"
    q.put(log)

def startProcesses():
    global p1
    global p2
    p1 = mp.Process(target = process1)
    p2 = mp.Process(target = process2)
    p1.start()
    p2.start()


def stopProcesses():
    p1.terminate()
    p2.terminate()
       
if __name__ == '__main__':
    q = mp.Queue()
    gui = Gui(q)
    p1 = mp.Process(target = process1, args=(q,))
    p2 = mp.Process(target = process2, args=(q,))
    p1.start()
    p2.start()
    gui.root.mainloop()

This is giving me this error:

Error:
TypeError: 'Queue' object is not callable

This happens when trying to execute "str = c_queue(0)" on CheckQueuePoll function.
I tried different ways of importing Queue, but I always get errors. I'd appreciate any help or hint in what I'm doing wrong.
Thanks in advance!
