[Tkinter] How can I use Tkinter with pygame

[microphone_head]

Making progress but still not there yet.

The examples i've see so far only use the method "mainloop" which looks like a wait until tkinter window has finished . I need the code to visit the window temporarily (and not close it) before doing more of my other stuff in pygame .

import tkinter as tk
import pygame

pygame.init()

pwbr_power = 0
pwbr_duration = 0
pwbr_scrn_refresh = 0
pwbr_elps_time = 0
pwbr_ttl_sec = 0

class Application(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.grid()
        self.createwidgets()
    # __init__() ---------------------------------------------------------------

    def createwidgets(self):
        """

        pwbr_scrn_refresh = 0.333
        pwbr_ttl_sec += pwbr_elps_time

        if pwbr_elps_time > pwbr_scrn_refresh:
