Make tkinter GUI window on top over omxplayer HDMI video screen

Question

I have a project of IOT where i am using python-3.6 on raspberry pi zero and tkinter for GUI.

Pi is always playing video on a TV with direct HDMI (omxplayer).

Problem: I need to open a tkinter GUI window to connect wifi but GUI display index is below than the omxplayer screen.

What i want I want to display GUI on top over omxplayer screen to connect wi-fi.

I have tried:

1 root.wm_attributes("-topmost", 1) 
  #Not working wm is not defined

2 root.overridedirect(1)
  root.wm_attributes("-topmost", 1)
  #Window is jumping on top of every other applications but not over omxplayer.

3 root.attributes("-topmost", 1)
  #Window is jumping on top of every other applications but not over omxplayer.

4 root.lift()
  #Not working

I got a solution although its not a valid solution.

What i did ?

Instead of making tkinter GUI on top i just bind hot key ctrl+j to hide omxplayer screen and ctrl+k to show screen.

from omxplayer.player import OMXPlayer
import omxplayer.keys
import codecs
from pynput import keyboard
import threading

xpress = False

# The key combination to check
COMBINATIONS = [
    {keyboard.Key.ctrl, keyboard.KeyCode(char='j')},
    {keyboard.Key.ctrl, keyboard.KeyCode(char='J')},
    {keyboard.Key.ctrl, keyboard.KeyCode(char='k')},
    {keyboard.Key.ctrl, keyboard.KeyCode(char='K')}
]

# The currently active modifiers
current = set()

def execute(key):
    keys = str(key).replace("'", "")
    print ("Do Something", keys)

    if keys == 'j':
        global xpress
        xpress = True
        print(xpress)
    else:
        xpress = False
        print(xpress)

def on_press(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        current.add(key)
        if any(all(k in current for k in COMBO) for COMBO in COMBINATIONS):
            execute(key)

def on_release(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        current.remove(key)

def ThKeyboad():
    with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
        listener.join()


t1 = threading.Thread(target=ThKeyboad, args=[])
t1.start()

#OMXPlayer Code

player = OMXPlayer('/home/pi/outhum/video/default.mp4', dbus_name='org.mpris.MediaPlayer2.omxplayer2')

if xpress:
    player.hide_video()
else:
    player.show_video()
a = player.duration()
time.sleep(a)
player.quit()

Please note that player is will hide on next omxplayer instance and same for unhiding. — Ajit Maurya, Apr 19 '19 at 09:07
