[Tkinter] How to create multilple tabs in tkinter from different classes

[CCChris91]

Hey, i've registered just to answer, fixed your code:

#!/usr/local/bin/python3
from tkinter import *
from tkinter import ttk
 
class App(Tk):
    def __init__(self,*args,**kwargs):
       Tk.__init__(self,*args,**kwargs)
       self.notebook = ttk.Notebook()
       self.add_tab()
       self.notebook.grid(row=0)
 
    def add_tab(self):
        tab = Area(self.notebook)
        tab2 = Volume(self.notebook) 
        self.notebook.add(tab,text="Tag")
        self.notebook.add(tab2,text="Tag2")
 
 
class Area(Frame):
   def __init__(self,name,*args,**kwargs):
       Frame.__init__(self,*args,**kwargs)
       self.label = Label(self, text="Hi This is Tab1")
       self.label.grid(row=1,column=0,padx=10,pady=10)
       self.name = name
 
class Volume(Frame):
   def __init__(self,name,*args,**kwargs):
       Frame.__init__(self,*args,**kwargs)
       self.label = Label(self, text="Hi This is Tab2")
       self.label.grid(row=1,column=0,padx=10,pady=10)
       self.name = name
 
my_app = App()
my_app.mainloop()

Not sure if it was really missing, or you've just forgot to copy it, but the mainloop() was missing from the end. Also, you only forgot to add 'self' from Label. This way you've put them under the main frame, instead of under their respective tab-frames. This way it works like you've designed it (i've tested it, works).
