  • First `command=display()` will execute `display()` immediately without clicking the button. `command=display` should be used instead. Second don't create more than one instance of `Tk()`, use `Toplevel()` for windows other than the root window. Also run `.mainloop()` only once. The image issue is the same as this [question](https://stackoverflow.com/questions/16424091/why-does-tkinter-image-not-show-up-if-created-in-a-function). – acw1668 Nov 05 '22 at 16:00
  • As I can see in `TestBtnImage1.py`, you are importing itself (`from TestBtnImage1 import *`). It should be `from TestBtnImage2 import *`, right? Also, @acw1668 has already explained, use `command=display` instead of `display()`... – Hung Nov 05 '22 at 16:27

There are a few problems in your code.

In TestBtnImage1.py

  • You are importing itself, which will cause a NameError.
    from TestBtnImage1 import *
    and you just need to change it to TestBtnImage2

  • The geometry specifier should be 'x'
    If you use frame.geometry('200*200'), it will cause tkinter bad geometry specifier error.
    So use 200x200 instead of 200*200.

  • The button command
    printButton = Button(frame, text="click me", command=display()).place(x=50, y=50)
    The display() function will automatically run when executed. You can remove the brackets ()
    -> printButton = Button(frame, text="click me", command=display).place(x=50, y=50)

(*) Also, the printButton (None) does nothing. So you can remove it.

In TestBtnImage2.py

  • Use Toplevel() instead of a new Tk()
    -> frame = Toplevel()

  • Again, bad geometry specifier. -> frame.geometry('200x200')

  • Use mainloop() only once. You can remove frame.mainloop() at the end of the function

(*) Also, Button(gui, text="click me", image=logo1, bg="blue", relief=FLAT).place(x=100, y=200)
The master gui is not defined.



So, the full code should be:
TestBtnImage1.py:

from tkinter import *
from TestBtnImage2 import *

frame = Tk()
frame.title("TextBox Input")
frame.geometry('200x200')
frame.config(background="blue")

Button(frame, text="click me", command=display).place(x=50, y=50)
frame.mainloop()

TestBtnImage2.py:

from tkinter import *


def display():
    frame = Toplevel()
    frame.title("TextBox Input")
    frame.geometry('200x200')
    frame.config(background="blue")

    logo1 = PhotoImage(file="cheta.png")
    Button(frame, text="click me", image=logo1, bg="blue",  relief=FLAT).place(x=100, y=200)
