I made a little login screen. After I put in the credentials I want the Tkinter to be closed and open a new python file. If you execute the code below it will give me the error NameError: name ttk is not defined. In the other file I imported everything and gave it the correct name.
The file I use for the login:
from tkinter import *
import tkinter.messagebox as tm
class LoginFrame(Frame):
def __init__(self, master):
super().__init__(master)
self.label_username = Label(self, text="Username")
self.label_password = Label(self, text="Password")
self.photo = PhotoImage(file="sbshreg.png")
self.label_image = Label(root, image=self.photo)
self.label_image.image = self.photo
self.entry_username = Entry(self)
self.entry_password = Entry(self, show="*")
self.label_username.grid(row=0, sticky=E)
self.label_password.grid(row=1, sticky=E)
self.label_image.grid(row=3, column=2, rowspan=2, columnspan=2, sticky=W, padx=10)
self.entry_username.grid(row=0, column=1, sticky=E)
self.entry_password.grid(row=1, column=1, sticky=E)
self.logbtn = Button(self, text="Login", command=self._login_btn_clicked)
self.logbtn.grid(columnspan=2, column=1, row=2, sticky=S+E+N+W)
self.grid()
def _login_btn_clicked(self):
username = self.entry_username.get()
password = self.entry_password.get()
if username == "123" and password == "123":
tm.showinfo("SBSHREG", "Welcome 123")
#The sweet spot where all goes wrong...
self.destroy()
exec(open("./BatchFrame.py").read())
else:
tm.showerror("SBSHREG", "Incorrect username")
root = Tk()
root.title("SBSHREG")
root.geometry("235x120")
lf = LoginFrame(root)
root.mainloop()
In the other file I got this: from tkinter import ttk as ttk which should prevent the error in the other file from happening.

If I change self.destroy() to root.destroy() I get the following error: _tkinter.TclError: can't invoke "label" command: application has been destroyed. In the second file the functions are not done yet because I'm still working on the file, but this shouldn't have any impact on the error.
I searched everywhere and tried a lot and I still got no clue whatsoever...
Consider initializing frames in a top level class, GUI, that handles opening of both frames where LoginFrame calls its parent's open_batch() (now lambda implemented) method. Below assumes LoginFrame.py and BatchFrame.py resides in same folder as GUI_App script.
In this way, scripts run as standalone modules on one Tk() instance.
