What is true about the unbind () method? (Select two answers.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Option B is true because theunbind()method is invoked from within a widget's object1.

Option D is true because theunbind()method needs the event name as an argument1.

Theunbind()method in Tkinter is used to remove a binding between an event and a function. It can be invoked from within a widget's object when a binding is no longer needed. The method requires the event name as an argument to remove the binding for that specific event. For example:

button = tk.Button(root, text='Click me')

button.bind('<Button-1>', callback_function) # bind left mouse click event to callback_function

button.unbind('<Button-1>') # remove the binding for the left mouse click event
