Activate multiple buttons when pressing one

Question

I'm doing my first GUI on Tkinter and I'm having some issues getting more than one button to activate after clicking one.

I have the button Main that's always active by default, and once it's pressed it should activate Button1, Button2, Button3, Button5 and Button6 that are disabled by default. This is my code at the moment.

Function that activates the buttons:

def activateButtons():
    for i in (Button1, Button2, Button3, Button5, Button6):
        i.config(state=ENABLED)

Button that calls the function:

loadDB= tk.Button(
  root,
  width=10,
  text = "Load DB.",
  bg = "black",
  fg = "blue",
  command=lambda:[loadDBF(),activateButtons()]).pack(expand = True)

and the buttons:

Button1 = tk.Button(
  root,
  width= 15,
  text= "Button 1",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Button2 = tk.Button(
  root,
  width= 15,
  text= "Button 2",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Button3 = tk.Button(
  root,
  width= 15,
  text= "Button3",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Button4 = tk.Button(
  root,
  width= 15,
  text= "Button 4",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Button4 = tk.Button(
  root,
  width= 15,
  text= "Button 1",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Button5 = tk.Button(
  root,
  width= 15,
  text= "Button 1",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Button6 = tk.Button(
  root,
  width= 15,
  text= "Button 1",
  bg="black",
  fg="blue",
  state=DISABLED).pack(expand = True)

Any idea on how to get them to activate once I press loadDB?

All of your `ButtonX` variables are None - the result of `.pack()`, rather than the Buttons themselves. This should be generating a `'NoneType' object has no attribute 'config'` when you try to activate them - are you not seeing that? — jasonharper, May 22 '22 at 03:18
How could I correct it? If I remove it they dissapear from the GUI — theJohnLewis, May 22 '22 at 03:20
Just found a way to do it thanks to this correction, thank you! — theJohnLewis, May 22 '22 at 03:22

Replace ENABLED with NORMAL.

def activateButtons():
    for i in (Button1, Button2, Button3, Button5, Button6):
        i.config(state=NORMAL)

I got: z.config(state=NORMAL) AttributeError: 'NoneType' object has no attribute 'config' – theJohnLewis May 22 '22 at 03:12
@theJohnLewis the function can't find your buttons then. Are you sure you have defined them with the correct scope? – Abhinav Mathur May 22 '22 at 03:13
It's my first time doing this so maybe not, how should they be defined? – theJohnLewis May 22 '22 at 03:14
@theJohnLewis You'll need to add more of your program to the question for that, making it easier to debug – Abhinav Mathur May 22 '22 at 03:15
That's pretty much all of it, the rest are functions that have nothing to do with the buttons – theJohnLewis May 22 '22 at 03:17
But where are you defining the buttons? Inside another function? – Abhinav Mathur May 22 '22 at 03:18
I thought that the way I wrote them was right, but I was just told that it's not. – theJohnLewis May 22 '22 at 03:20
I think I got it now – theJohnLewis May 22 '22 at 03:21
