Ciao a tutti
Ho un problema con la grid e cioè quando gli inserisco dei label all'interno la celle si restringe alle dimensioni del label ma questo io non vorrei questo è il pezzo di codice:

codice:
Def funzione:

   lblPerimeter.pack()
   lblFormulePerimeter.pack()
   lblTitleEsemple.pack()
   lblEsemple1.pack()
   lblArea.pack(pady=10)
   lblFormuleArea.pack()
   lblTitleEsemple2.pack(pady=20)
   lblEsemple2.pack()f3 = Frame(f2, width=275, height=250, bg="red")
f3.grid(row=1, column=0)
f3.grid_propagate(False)
f4 = Frame(f2, width=275, height=250, bg="yellow")
f4.grid(row=1, column=1)
f4.grid_propagate(False)
f5 = Frame(f2, width=275, height=250, bg="white")
f5.grid(row=2, column=0)
f5.grid_propagate(False)
f6 = Frame(f2, width=275, height=250, bg="white")
f6.grid(row=2, column=1)
f6.grid_propagate(False)lblPerimeter= Label(f3, text="Perimetro", font=('arial', 12, 'bold'), fg='black', bg='white')
lblPerimeter.pack_forget()

lblFormulePerimeter = Label(f3, textvariable=txtPerimeter,
font=('times', 12, 'italic'), fg='black', bg='white')
lblFormulePerimeter.pack_forget()

lblTitleEsemple = Label(f3, font=('arial', 12, 'italic'), fg='black', bg='white', text='Esempio', state=DISABLED)
lblTitleEsemple.pack_forget()

lblEsemple1 = Label(f3, textvariable=txtEsemple,
font=('arial', 12), fg='black', bg="white")
lblEsemple1.pack_forget()

lblArea= Label(f5, text="Perimetro", font=('arial', 12, 'bold'), fg='black', bg='white', state=DISABLED)
lblArea.pack_forget()

lblFormuleArea = Label(f5, textvariable=textArea,
font=('times', 12, 'italic'), fg='black', bg='white')
lblFormuleArea.pack_forget()

lblTitleEsemple2 = Label(f5, font=('arial', 12, 'italic'), fg='black', bg='white', text='Esempio', state=DISABLED)
lblTitleEsemple2.pack_forget()

lblEsemple2 = Label(f5, textvariable=txtEsemple2,
font=('arial', 12), fg='black', bg="white")
lblEsemple2.pack_forget()

showCanvas = Canvas(f4, width=275, height=250, bg='white')
showCanvas.pack_forget()funzione()
