For my program I need to change the list of acceptable values based on updated information from the user. Is there any method to do that, or a property I can overwrite?
I tried simply:
col_spinbox.values = spin_vals
where spin_vals is the tuple of values I want, and col_spinbox is the instance for which I'm trying to overwrite the accepted values. But this didn't work.
From investigation it seems that the property values is stored as a string with spaces in between each value. So I formatted spin_vals that way, and it still didn't work. Is there a method that is intended to be used or is there just no way of overwriting the acceptable values?
One common way to change the properties or options of a tkinter widget is to use the universal config() widget method — and doing this to a Spinbox's values option does indeed work.
Simple example.
import tkinter as tk
root = tk.Tk()
spinbox = tk.Spinbox(root, values=('red', 'blue', 'green'))
spinbox.pack()
def new_values(spinbox):
spinbox.config(values=('yellow', 'cyan', 'magenta'))
chg_btn = tk.Button(root, text="Chg", command=lambda: new_values(spinbox))
chg_btn.pack()
root.mainloop()
