CTkTabview

The CTkTabview creates a tabview, similar to a notebook in tkinter. The tabs, which are created with .add("<tab-name>") are CTkFrames and can be used like CTkFrames. Any widgets can be placed on them.

Example Code:

Example without using classes (not recommended):

tabview = customtkinter.CTkTabview(app)
tabview.pack(padx=20, pady=20)

tabview.add("tab 1")  # add tab at the end
tabview.add("tab 2")  # add tab at the end
tabview.set("tab 2")  # set currently visible tab

button_1 = customtkinter.Button(tabview.tab("tab 1"))
button_1.pack(padx=20, pady=20)

It's also possible to save tabs in extra variables:

tab_1 = tabview.add("tab 1")
tab_2 = tabview.add("tab 2")

button_1 = customtkinter.Button(tab_1)

Example with classes (recommended):

import customtkinter


class MyTabView(customtkinter.CTkTabview):
    def __init__(self, master, **kwargs):
        super().__init__(master, **kwargs)

        # create tabs
        self.add("tab 1")
        self.add("tab 2")

        # add widgets on tabs
        self.label = customtkinter.CTkLabel(master=self.tab("tab 1"))
        self.label.grid(row=0, column=0, padx=20, pady=10)


class App(customtkinter.CTk):
    def __init__(self):
        super().__init__()

        self.tab_view = MyTabView(master=self)
        self.tab_view.grid(row=0, column=0, padx=20, pady=20)


app = App()
app.mainloop()
