Tkinter messagedialog askyesno with a checkbox?

Is it possible to make a Tkinter yes/no messagebox with a checkbox, for something like 'Never ask me again'?
Or would I have to create another window, create my own Labels and CheckButtons, and basically create my own dialog?

You should create your own dialog box then.
Here’s what you can do:
from tkinter import *
def popup():
popupWin = Toplevel()
popupWin.title(“Continue?”)
checkVariable = IntVar()
lbl = Label(popupWin, text=“Continue?)
lbl.pack()
btn2 = Button(popupWin, text=“Yes”)
btn2.pack()
btn3 = Button(popupWin, text=“No”)
btn3.pack()
checkBox = Checkbutton(popupWin, text=“Don’t ask again”, variable=checkVariable)
root = Tk()
btn = Button(root, text=Message Box, command=popup)
root.mainloop()

how to bind button in tkinter

import tkinter as tk
from tkinter import ttk
root = tk.Tk()
root.title("Tic Tac Toe")
root.geometry("505x500")
root.resizable(0,0)
Blank = tk.PhotoImage(file='Blank.png')
X = tk.PhotoImage(file='X.png')
O = tk.PhotoImage(file='O.png')
def configB(event):
print('hello')
btn1 = tk.Button(root,image=Blank)
btn1.place(x=0,y=0)
btn2 = ttk.Button(image=Blank)
btn2.place(x=165,y=0)
btn3 = ttk.Button(image=Blank)
btn3.place(x=330,y=0)
btn4 = ttk.Button(image=Blank)
btn4.place(x=0,y=165)
btn5 = ttk.Button(image=Blank)
btn5.place(x=165,y=165)
btn6 = ttk.Button(image=Blank)
btn6.place(x=330,y=165)
btn7 = ttk.Button(image=Blank)
btn7.place(x=0,y=330)
btn8 = ttk.Button(image=Blank)
btn8.place(x=165,y=330)
btn9 = ttk.Button(image=Blank)
btn9.place(x=330,y=330)
btn1.bind('<Return>',configB)
root.mainloop()
i want to bind btn1 and i want it to work when i press enter but nothing happens when i press enter as per my code it should print hello .
please help thanks in advance.

As #jasonharper said it will work only if button is focused
btn1.focus()
btn1.bind('<Return>', configB)
and if you click other button then it will not work again
so better bind to main winodw
root.bind('<Return>', configB)
Minimal working code
import tkinter as tk
# --- functions --- # PEP8: lower_case_names
def config_b(event):
print('hello')
# --- main ---
root = tk.Tk()
btn1 = tk.Button(root, text='1')
btn1.pack()
btn1 = tk.Button(root, text='2')
btn1.pack()
#btn1.focus()
#btn1.bind('<Return>', config_b)
root.bind('<Return>', config_b)
root.mainloop()

There is no quick answer to this question.
Buttons must be bound so as to duplicate (as close as possible) normal button behaviour.
This includes changing button relief and colors, then restoring button.
Finally it has to execute the button command.
The following example does this for two buttons.
'button' responds to Mouse 'Button-3'
'buttonX' responds to Key 'Return'
import tkinter as tk
def working():
print("Working...")
def actionPress(event):
event.widget.config(
relief = "sunken",
background = "red",
foreground = "yellow")
def actionRelease(event):
event.widget.config(
relief = "raised",
background = "SystemButtonFace",
foreground = "SystemButtonText")
# activate buttons' command on release
event.widget.invoke()
window = tk.Tk()
button = tk.Button(window, text = "press", command = working)
button.pack()
buttonX = tk.Button(window, text = "pressX", command = working)
buttonX.pack()
# bind returns unique ID
boundP = button.bind("<ButtonPress-3>", actionPress)
boundR = button.bind("<ButtonRelease-3>", actionRelease)
boundXP = buttonX.bind("<KeyPress-Return>", actionPress)
boundXR = buttonX.bind("<KeyRelease-Return>", actionRelease)
# This is how to unbind (if necessary)
# button.unbind(""<ButtonPress-3>", boundP)
# button.unbind(""<ButtonRelease-3>", boundR)
# buttonX.unbind(""<KeyPress-Return>", boundXP)
# buttonX.unbind(""<KeyRelease-Return>", boundXR)
window.mainloop()

You don't need parameter in configB method. Also don't need bind for button1. I also add command in button1 widget. Comment out in line 36 #btn1.bind('<Return>',configB)
def configB():
print('hello')
btn1 = tk.Button(root, command=configB)
Result:
Btw, I don't have png image.

Why Does "mainloop()" For One Window Open Multiple Windows?

I'm using Tkinter. For whatever reason, "Window1.mainloop()" in this script opens both Window1 and Window2. Also, pressing the button on Window1 doesn't open Window2, but I think that's unrelated.
import tkinter as tk
Window1 = tk.Tk()
Window1.title("Window 1")
Window1.geometry("300x200")
Window2 = tk.Tk()
Window2.title("Window 2")
Window2.geometry("150x100")
def RunWindow2():
Window2.mainloop()
Button1 = tk.Button(Window1, text = "Open Window 2.", command = RunWindow2)
Button1.pack()
Label1 = tk.Label(Window2, text = "This is Window 2.")
Label1.pack()
Window1.mainloop()

How to display text on a new window Tkinter?

I've started learning Tkinter on Python few weeks ago and wanted to create a Guess Game. But unfortunately I ran into a problem, with this code the text for the rules ( in the function Rules; text='Here are the rules... ) doesn't appear on the window ( rule_window).
window = Tk()
window.title("Guessing Game")
welcome = Label(window,text="Welcome To The Guessing Game!",background="black",foreground="white")
welcome.grid(row=0,column=0,columnspan=3)
def Rules():
rule_window = Tk()
rule_window = rule_window.title("The Rules")
the_rules = Label(rule_window, text='Here are the rules...', foreground="black")
the_rules.grid(row=0,column=0,columnspan=3)
rule_window.mainloop()
rules = Button(window,text="Rules",command=Rules)
rules.grid(row=1,column=0,columnspan=1)
window.mainloop()
Does anyone know how to solve this problem?

In your code you reset whatever rule_window is to a string (in this line: rule_window = rule_window.title(...))
Try this:
from import tkinter *
window = Tk()
window.title("Guessing Game")
welcome = Label(window, text="Welcome To The Guessing Game!", background="black", foreground="white")
welcome.grid(row=0, column=0, columnspan=3)
def Rules():
rule_window = Toplevel(window)
rule_window.title("The Rules")
the_rules = Label(rule_window, text="Here are the rules...", foreground="black")
the_rules.grid(row=0, column=0, columnspan=3)
rules = Button(window, text="Rules", command=Rules)
rules.grid(row=1, column=0, columnspan=1)
window.mainloop()
When you want to have 2 windows that are responsive at the same time you can use tkinter.Toplevel().

In your code, you have initialized the new instances of the Tkinter frame so, instead of you can create a top-level Window. What TopLevel Window does, generally creates a popup window kind of thing in the application. You can also trigger the Tkinter button to open the new window.
from tkinter import *
from tkinter import ttk
#Create an instance of tkinter window
root= Tk()
root.geometry("600x450")
#Define a function
def open_new():
#Create a TopLevel window
new_win= Toplevel(root)
new_win.title("My New Window")
#Set the geometry
new_win.geometry("600x250")
Label(new_win, text="Hello There!",font=('Georgia 15 bold')).pack(pady=30)
#Create a Button in main Window
btn= ttk.Button(root, text="New Window",command=open_new)
btn.pack()
root.mainloop()

How to compulsory close message box for Toplevel window

image for that
I have few lines of code here which is login system which works fine but i can click on the Toplevel button multiple times when i provide the wrong password without closing the messagebox.How can i make it so that it has to be closed messagebox before i can make attempt again.
from tkinter import *
from tkinter import messagebox
def top():
if entry1.get() == "333":
log.destroy()
root.deiconify()
else:
messagebox.showerror("error", "try again")
root = Tk()
root.geometry("300x300")
log = Toplevel(root)
log.geometry("200x200")
label1 = Label(log, text="password")
entry1 = Entry(log)
button1 = Button(log, text="login", command=top)
label1.pack()
entry1.pack()
button1.pack(side="bottom")
lab = Label(root, text="welcome bro").pack()
root.withdraw()
root.mainloop()

You need to make the log window the parent of the dialog:
messagebox.showerror("error", "try again", parent=log)
By default it will use the root window (the Tk instance) as the parent which in this case is not what you want.

With hint from #furas this how to implement this:
create another function to the call it when the entry doesn't match and use grab_set method for the Toplevel window tp.grab_set().You can add your customarised image to the Toplevel window as well as message to display in the box(here: i use label to depict that)
from tkinter import *
from tkinter import messagebox
def dialog(): # this function to call when entry doesn't match
tp = Toplevel(log)
tp.geometry("300x100")
tp.title('error')
tp.grab_set() # to bring the focus to the window for you to close it
tp.resizable(width=False, height=False)
l = Label(tp, text="try again\n\n\n\n add your customarize image to the window")
l.pack()
def top():
if entry1.get() == "333":
log.destroy()
root.deiconify()
else:
dialog() # being called here
root = Tk()
root.geometry("300x300")
log = Toplevel(root)
log.geometry("200x200")
label1 = Label(log, text="password")
entry1 = Entry(log)
button1 = Button(log, text="login", command=top)
label1.pack()
entry1.pack()
button1.pack(side="bottom")
lab = Label(root, text="welcome bro").pack()
root.withdraw()
root.mainloop()
