将Tkinter框架放置在另一个框架中

Question

I am trying to experiment and get the button to only display the label when the button is clicked instead it is opening up another GUI window. The main frame is called secret message. Within this when i click onto the button it should then replace the empty place with the label in row=2 .

Could someone explain to me how i can raise the label rather than just opening up a new window. All code is functional but i want another way around this, i am new to python.

from tkinter import *

def topLevel():
    top=Toplevel()
    top.geometry("300x200")

root=Tk()
root.title("Secret Message")

button1 = Button(text="Push this button to see hidden message!", width =60, command=topLevel)
button1.grid(row=1, column=0)    

label1 = Label(width=50, height=10, background="WHITE", text= "There is no secret!")
label1.grid(row=2, column=0)

root.mainloop()

Answer 1

You question title has nothing to do with your question.

To update the geometry of your label you simple need to tell the function where you want the label on the container you set up your label in. In this case you do not define the container so the widgets default to the root window.

Here is a working example that will update the label geometry when you press the button.

from tkinter import *


root=Tk()
root.title("Secret Message")

def grid_label():
    label1.config(text="There is no secret!")

Button(root, text="Push this button to see hidden message!", width=60, command=grid_label).grid(row=1, column=0)    
label1 = Label(root, width=50, height=10, background="WHITE")
label1.grid(row=2, column=0)

root.mainloop()
