Why I got AttributeError: 'Text' object has no attribute 'trace_variable?

Question

Please Help me....

Here my code:

from tkinter import *
root=Tk()
def retrieve_input():
inputValue=textBox.get("1.0","end-1c")
print(inputValue)

textBox=Text(root, height=2, width=10)
textBox.pack()

def limiter(*args):
limit = 5
s = textBox.get()
if len(s) > limit:
textBox.set(s[:limit])

textBox.trace_variable("w",limiter)

buttonCommit=Button(root,height=1,width=10,text="Commit",command=lambda:retrieve_input())

buttonCommit.pack()

mainloop()

Answer 1

there is no trace_variable function in Text. What are you trying to accomplish?
