having problems in tkinter

Question

Hi this Adorable Trooper.

Currently, typing a basic recurring deposit calculator.

I have already wrote some code regarding the basic tabs layout for it.

I have also made a new tab, but the data which I want it to be displayed on it, seems to be in error.

from tkinter import *

root = Tk()
root.geometry("400x200")
root.title("Recurrinng deposit calculator.")
img = PhotoImage(file="Adorable trooper logo.png")
root.iconphoto(False, img)

# Creating a label to show The Title of the program.

TITLE = Label(root, text= "Recurring Deposits Calculator.", bg= "red", padx= 1000)
TITLE.pack()

# Definning functions for the RADIO BUTTON.
def display_intro():
    root1 = Toplevel(root)
    root1.title("Intro about Recurring deposits Calculator.")
    info_frame = LabelFrame(root1, text="Intro about Recurring Deposits Calculator.")
    info_frame.pack(fill="both", expand="yes")
    info = Label(LabelFrame, text= "This is basically a basic calculator")
    info.pack()
    root1.mainloop()
var = IntVar()


# Displaying some Radio Buttons related to their command.

introduction_button = Radiobutton(root, text= "Introduction", command= display_intro, variable=var, value= 1)
introduction_button.pack(anchor = W)

root.mainloop()

This is the error.

Exception in Tkinter callback

If anyone finds it's solution or maybe guiding me on this error, please reply as soon as possible.

Answer 1

Instead of making the parent widget of the widget info the LabelFrame, which is a class, you should make it info_frame. This way, it will go inside the LabelFrame. You can't pass a method as a parent in tkinter.

So, the full code:

from tkinter import *

root = Tk()
root.geometry("400x200")
root.title("Recurrinng deposit calculator.")
img = PhotoImage(file="yes.png")
root.iconphoto(False, img)

# Creating a label to show The Title of the program.

TITLE = Label(root, text= "Recurring Deposits Calculator.", bg= "red", padx= 1000)
TITLE.pack()

# Definning functions for the RADIO BUTTON.
def display_intro():
    root1 = Toplevel(root)
    root1.title("Intro about Recurring deposits Calculator.")
    info_frame = LabelFrame(root1, text="Intro about Recurring Deposits Calculator.")
    info_frame.pack(fill="both", expand="yes")
    info = Label(info_frame, text= "This is basically a basic calculator")
    info.pack()
    root1.mainloop()
var = IntVar()


# Displaying some Radio Buttons related to their command.

introduction_button = Radiobutton(root, text= "Introduction", command= display_intro, variable=var, value= 1)
introduction_button.pack(anchor = W)

root.mainloop()

Output:
