I don't know but i hope this will work. If you normally starting a **def function**, the programm will wait until the function is finished. Also the `window.mainloop()` function stops...

It does'nt work, because you tried to put a **string** in a **int** variable. So use `tkinter.StringVar()` except of `tkinter.IntVar()` If you then want the **int** out of the **string**,...

I have never use `state` on tabview, but on button, entry and slider. I didn't wrote `state = tk.ACTIVE` I wrote `state = "disabled"` (for _disable_) or `state = "normal"`...
