How to Bind the Enter Key to a Function in Tkinter

How do I bind the enter key to a function in tkinter?

Try running the following program. You just have to be sure your window has the focus when you hit Return--to ensure that it does, first click the button a couple of times until you see some output, then without clicking anywhere else hit Return.

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")
root.bind('<Return>', func)

def onclick():
    print("You clicked the button")

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Then you just have tweak things a little when making both the button click and hitting Return call the same function--because the command function needs to be a function that takes no arguments, whereas the bind function needs to be a function that takes one argument(the event object):

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event=None):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Or, you can just forgo using the button's command argument and instead use bind() to attach the onclick function to the button, which means the function needs to take one argument--just like with Return:

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me")
button.bind('<Button-1>', onclick)
button.pack()

root.mainloop()

Here it is in a class setting:

import tkinter as tk

class Application(tk.Frame):
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry("300x200")

        tk.Frame.__init__(self, self.root)
        self.create_widgets()

    def create_widgets(self):
        self.root.bind('<Return>', self.parse)
        self.grid()

        self.submit = tk.Button(self, text="Submit")
        self.submit.bind('<Button-1>', self.parse)
        self.submit.grid()

    def parse(self, event):
        print("You clicked?")

    def start(self):
        self.root.mainloop()

Application().start()

How to bind enter key to a tkinter button

2 things:

You need to modify your function to accept the argument that bind passes. (You don't need to use it, but you need to accept it).

def enter(event=None):

And you need to pass the function, not the result, to the bind method. So drop the ().

bt.bind('<Return>',enter)

Note this binds Return to the Button, so if something else has focus then this won't work. You probably want to bind this to the Frame.

fr.bind('<Return>',enter)

If you want a way to push an in focus Button the space bar already does that.

I have tried to bind my Tkinter button to the Enter key on the keyboard but it is not working

You have provide all the necessary parameters while you bind the Button to Enter-Event
Try this:

Next_button.bind("<Return>", lamnda event: check(FName_Entry, LName_Entry, Age_Entry, Phone_Entry))

How to bind the Enter key to a button in Tkinter

You need to use a lambda if you're passing arguments.

app.bind("<Return>", lambda x: showLDAPMembers(yourName,yourPassword))

The bind command automatically returns the event that called it, so you need to define and throw away that (with lambda x:)

How do I activate button click with the Enter key in Tkinter?

Bind the return key to a function and from that function call the clk function.

from tkinter import *
import tkinter. messagebox

root=Tk()
root.geometry('250x250')
root.title("Meta' Translator")
root.configure(background="#35424a")

#Entry widget object
textin = StringVar()

def returnPressed(event):
  clk()
  
def clk():
    entered = ent.get()
    output.delete(0.0,END)
    try:
      textin = exlist[entered]
    except:
      textin = 'Word not found'
    output.insert(0.0,textin)

#heading
lab0=Label(root,text='Translate English Words to Meta\'',bg="#35424a",fg="silver",font=('none 11 bold'))
lab0.place(x=0,y=2)

#Entry field
ent=Entry(root,width=15,font=('Times 18'),textvar=textin,bg='white')
ent.place(x=30,y=30)

#focus on entry widget
ent.focus()

#Search button
but=Button(root,padx=1,pady=1,text='Translate',command=clk,bg='powder blue',font=('none 18 bold'))
but.place(x=60,y=90)

root.bind('<Return>', returnPressed)

#output field
output=Text(root,width=15,height=1,font=('Times 18'),fg="black")
output.place(x=30,y=170)

#prevent sizing of window
root.resizable(False,False) 

#Dictionary
exlist={
    "abdomen":"fɨbûm", "abdomens":"tɨbûm",
    "adam's apple":"ɨ̀fɨ̀g ədɔ'",
    "ankle":"ɨgúm ǝwù", "ankles":"tɨgúm rəwù",
    "arm":"ǝbɔ́", "arms":"ɨbɔ́",
    "armpit":"ǝtón rɨ̀ghá"
    }

root.mainloop()

How can I bind the Return key and button widget to the same function on Tkinter?

You can use lambda in bind() as well:

entry.bind("<Return>", lambda e: but_test(entry.get()))

PYTHON TKINTER e = Entry() e.bind('ENTER', function)

The ENTER should be changed with Return, and the function should accept an event

Also, don't forget in a 'class' to use self in the method and self.method to call it.

     def up_R(self, event):
            print('Makes it here')
            self.R.update_disp(self.e.get())
            self.rl.config(text=self.R.dkey)
            
        self.e.bind('<Return>', self.up_R)

Is there a function to switch Tab and Enter button in tkinter?

You can bind the <Return> key event on the Entry widget. Then in the bind callback, get the next widget in the focus order by .tk_focusNext() and move focus to this widget:

import tkinter as tk

root = tk.Tk()

for i in range(10):
    e = tk.Entry(root)
    e.grid(row=0, column=i)
    e.bind('<Return>', lambda e: e.widget.tk_focusNext().focus_set())

root.mainloop()
