Why doesn’t the .bind() method work with a frame widget in Tkinter?

This code is an attempt to bind a command to a frame, ie. when the “Escape” key is pressed, the window should be destroyed.

from tkinter import *
from tkinter import ttk

root=Tk()
root.geometry("400x400")

frame1=ttk.Frame(root)
frame1.pack()

def Exit(event):
    root.destroy()

frame1.bind("<Escape>", Exit)

root.mainloop()

from tkinter import *
from tkinter import ttk
​
root=Tk()
root.geometry("400x400")
​
frame1=ttk.Frame(root)
frame1.pack()
​
def Exit(event):
    root.destroy()
​
frame1.bind("<Escape>", Exit)
​
root.mainloop()
​

if frame1.bind() is replaced by root.bind(), the code works as I would expect it to. Why doesn’t what I’ve written above work?

Answer

The bind works, but the event will only trigger if the frame has focus, and by default a frame does not have the keyboard focus.

Try setting the focus with frame1.focus_set()
