Tkinter：在另一个文件中使用条目值

Question

When file1.py runs and the submit button is hit, the submit method will return entry.get() value, which is fine. However, if I wanted too transfer the entry.get() too another python file when the submit button is hit. Is this possible?

file1.py

from tkinter import *

root = Tk()

def submit():
    return entry.get()

entry = Entry(root)
entry.pack()
submit_button = Button(root, text = "Submit", command = submit)
submit_button.pack()

root.mainloop()

file2.py

import file1 as f1
from tkinter import messagebox
var = submit()
if var == "test":
   messagebox.showinfo("Hello")

This is what I'm wanting to do but having no luck with it atm.

Answer 1

You can pass the value to a function that you have defined in the other file like this.

p1.py

from tkinter import *
from p2 import new_print

root = Tk()

def submit():
    new_print(entry.get())

entry = Entry(root)
entry.pack()
submit_button = Button(root, text = "Submit", command = submit)
submit_button.pack()

root.mainloop()

p2.py

value_from_p1 = None

def new_print(value):
    global value_from_p1
    value_from_p1 = value
    print(value)
