calling function from another class in button command

Question

I want to call the showallrecords1 function from the car class when I push a button in the "gett" class.

I get the error

'gett' object has no attribute 'car'

Here is the related part of my code

from tkinter import *
import tkinter as tk

conn = sqlite3.connect('jadval.db')
c = conn.cursor()

        frame.pack()

##        bottomframe = Frame(master)

        self.master=master

        a= StringVar()
        b= StringVar()
        a1= StringVar()

        self.button = Button(frame,text="memory", command=self.ouvrir)
        self.button.pack(side=LEFT)

        self.button20.pack(side=LEFT)


        self.button30 = Button(frame,text="empty weight", command=self.weighing)

This is not related part of your code. This is your whole code... Try to minimalize it for related part as you said. — Erik Šťastný

The gett class has no member called "car". You have to define it somewhere inside the class definition. I. e.:

self.car = car(master)
