Turtle circle shape in a main GUI TK - python-3.x

Question

First of all, thanks for stopping by into my post. I'm a amateur Python writer. Right now, I'm writing a code that will control some Agilent instruments, into my GUI I need to display a virtual LED that can show to the operator the current test progress status, like, yellow = testing, green = passed, red= failed.
I found that turtle module can easily create a circle by adding turtle.shape('cicle'), please see below a turtle code I have:
I want to make it clear, I did not wrote the below code, I found the code in this webpage.
from turtle import Screen, Turtle
CURSOR_SIZE = 30
def blink():
pen, fill = turtle.color()
turtle.color(fill, pen)
screen.ontimer(blink, 500) # 1/4 second blink
screen = Screen()
turtle = Turtle()
turtle.hideturtle()
turtle.shape('circle')
turtle.shapesize(50 / CURSOR_SIZE)
turtle.color('red', 'Yellow')
turtle.showturtle()
blink()
So, I want to place the button into my main GUI window:
########## Main Window Design##########
main = Tk()
main.geometry('860x500+65+0')
main.title('Firmware Upgrade System 1.0')
Label(main,text='Firmware Upgrade System 1.0', font=("Tahoma", 20)).place(x=0,y=0)
##! UUT 1 ####################################
LabelFrame(main, text=' UUT 1 INFORMATION : ', font=("Tahoma", 10), height=120, width=420, bd=2, relief='groove' ).place(x=10,y=40)
LabelFrame(main, text='Serial Number',font=("Tahoma", 10), height=47, width=110, bd=3, relief='ridge').place(x=13,y=60)
LabelFrame(main, text='Firmware Version',font=("Tahoma", 10), height=47, width=119, bd=3, relief='ridge').place(x=126,y=60)
def fw_upgrade():
print("pas")
blink()
#######Buttons and Functions
Button(main, text="FIRMWARE UPGRADE", font=("Tahoma", 12), height=1, width=20, command=fw_upgrade).place(x=450,y=440)
So, every time I execute the code, it opens a secondary window with the virtual LED. How to incorporate into my main GUI?
Thanks for your help...

Answer 1

The regular Turtle and Screen always create a new window.
The turtle module has another RawTurtle class which works exactly the same as Turtle, but draws on an existing tk.Canvas, turtle.TurtleScreen or turtle.Screen instance that you must provide. Take a look at the turtle docs, they have lots of examples too
You should also call mainloop() on the Tk() window at the end of your code so that the window stays open.
(It's also a good idea to store the instances of your LabelFrames and all the widgets in variables if you're likely to change any of their properties or text later on)
from tkinter import Tk, Label, LabelFrame, Button, Canvas
from turtle import TurtleScreen, RawTurtle
def fw_upgrade():
print("pas")
########## Main Window Design##########
main = Tk()
main.geometry('860x500+65+0')
main.title('Firmware Upgrade System 1.0')
label1 = Label(main,text='Firmware Upgrade System 1.0', font=("Tahoma", 20))
label1.place(x=0,y=0)
##! UUT 1 ####################################
frame1 = LabelFrame(main, text=' UUT 1 INFORMATION : ', font=("Tahoma", 10), height=120, width=420, bd=2, relief='groove' )
frame1.place(x=10,y=40)
frame2 = LabelFrame(main, text='Serial Number',font=("Tahoma", 10), height=47, width=110, bd=3, relief='ridge')
frame2.place(x=13,y=60)
frame3 = LabelFrame(main, text='Firmware Version',font=("Tahoma", 10), height=47, width=119, bd=3, relief='ridge')
frame3.place(x=126,y=60)
btn = Button(main, text="FIRMWARE UPGRADE", font=("Tahoma", 12), height=1, width=20, command=fw_upgrade)
btn.place(x=450,y=440)
canv = Canvas(main)
turtlescr = TurtleScreen(canv)
canv.place(x=0, y=100)
CURSOR_SIZE = 30
turtle = RawTurtle(turtlescr)
turtle.hideturtle()
turtle.shape('circle')
turtle.shapesize(50 / CURSOR_SIZE)
turtle.color('red', 'Yellow')
turtle.showturtle()
main.mainloop()
