Python messagebox error

Модуль Tkinter messagebox в Python используется для отображения окон сообщений в приложениях Python. Существуют различные функции, которые используются для отображения соответствующих сообщений в зависимости от требований приложения.

Синтаксис для использования окна сообщений приведен ниже.

Синтаксис:

 
messagebox.function_name(title, message [, options]) 

Параметры

• function_name: представляет соответствующую функцию окна сообщения.
• title: это строка, которая отображается как заголовок окна сообщения.
• message: это строка, которая будет отображаться как непосредственное сообщение в окне сообщения.
• options: различные параметры, которые можно использовать для настройки диалогового окна сообщения.

Можно использовать два параметра: default и parent.

1. default.

Параметр по умолчанию используется для упоминания типов кнопки по умолчанию, то есть ABORT, RETRY или IGNORE в окне сообщения.

2. parent.

Опция parent указывает родительское окно, поверх которого должно отображаться окно сообщения.

Для отображения соответствующих окон сообщений используются следующие функции. Все функции используются с одинаковым синтаксисом, но имеют определенные значения.

1. showinfo()

Окно сообщений showinfo() используется там, где нам нужно показать пользователю некоторую релевантную информацию.

Пример:

 
# !/usr/bin/python3 
 
from tkinter import * 
 
from tkinter import messagebox 
 
top = Tk() 
 
top.geometry("100x100")     
 
messagebox.showinfo("information","Information") 
 
top.mainloop() 

Вывод:

2. showwarning()

Этот метод используется для отображения предупреждения пользователю. Рассмотрим следующий пример.

Пример:

 
# !/usr/bin/python3 
from tkinter import * 
 
from tkinter import messagebox 
 
top = Tk() 
top.geometry("100x100") 
messagebox.showwarning("warning","Warning") 
 
top.mainloop() 

Вывод:

3. showerror()

Этот метод используется для отображения сообщения об ошибке пользователю. Рассмотрим следующий пример.

Пример:

 
# !/usr/bin/python3 
from tkinter import * 
from tkinter import messagebox 
 
top = Tk() 
top.geometry("100x100") 
messagebox.showerror("error","Error") 
top.mainloop() 

Вывод:

4. askquestion()

Этот метод используется, чтобы задать пользователю вопрос, на который можно ответить утвердительно или нет. Рассмотрим следующий пример.

Пример:

 
# !/usr/bin/python3 
from tkinter import * 
from tkinter import messagebox 
 
top = Tk() 
top.geometry("100x100") 
messagebox.askquestion("Confirm","Are you sure?") 
top.mainloop() 

Вывод:

5. askokcancel()

Этот метод используется для подтверждения действий пользователя в отношении некоторых действий приложения. Рассмотрим следующий пример.

Пример:

 
# !/usr/bin/python3 
from tkinter import * 
from tkinter import messagebox 
 
top = Tk() 
top.geometry("100x100") 
messagebox.askokcancel("Redirect","Redirecting you to www.javatpoint.com") 
top.mainloop() 

Вывод:

6. askyesno()

Этот метод используется, чтобы спросить пользователя о каком-либо действии, на которое пользователь может ответить утвердительно или нет. Рассмотрим следующий пример.

Пример:

 
# !/usr/bin/python3 
from tkinter import * 
from tkinter import messagebox 
 
top = Tk() 
top.geometry("100x100") 
messagebox.askyesno("Application","Got It?") 
top.mainloop() 

Вывод:

7. askretrycancel()

Этот метод используется, чтобы спросить пользователя, нужно ли снова выполнять определенную задачу. Рассмотрим следующий пример.

Пример:

 
# !/usr/bin/python3 
from tkinter import * 
from tkinter import messagebox 
 
top = Tk() 
top.geometry("100x100") 
messagebox.askretrycancel("Application","try again?") 
 
top.mainloop() 

Вывод:

Окна сообщений

Tkinter имеет ряд встроенных окон для разных ситуаций, в частности, окна сообщений, функционал которых заключен в модуле tkinter.messagebox.
Для отображения сообщений этот модуль предоставляет следующие функции:

• showinfo(): предназначена для отображения некоторой информации

• showerror(): предназначена для отображения ошибок

• showwarrning(): предназначена для отображения предупреждений

Все эти функции принимают три параметра:

showinfo(title, message, **options)
showerror(title, message, **options)
showwarrning(title, message, **options)

• title: заголовок окна

• message: отображаемое сообщение

• options: настройки окна

В реальности различие между этими типами сообщений заключается лишь в изображении, которое отображается рядом с текстом сообщения:

from tkinter import *
from tkinter import ttk
from tkinter.messagebox import showerror, showwarning, showinfo

root = Tk()
root.title("METANIT.COM")
root.geometry("250x200")

def open_info(): 
    showinfo(title="Информация", message="Информационное сообщение")

def open_warning(): 
    showwarning(title="Предупреждение", message="Сообщение о предупреждении")

def open_error(): 
    showerror(title="Ошибка", message="Сообщение об ошибке")

info_button = ttk.Button(text="Информация", command=open_info)
info_button.pack(anchor="center", expand=1)

warning_button = ttk.Button(text="Предупреждение", command=open_warning)
warning_button.pack(anchor="center", expand=1)

error_button = ttk.Button(text="Ошибка", command=open_error)
error_button.pack(anchor="center", expand=1)

root.mainloop()

Здесь по нажатию на каждую из трех кнопок отображается соответствующее сообщение:

Окна подтверждения операции

Модуль tkinter.messagebox также предоставляет ряд функций для подтверждения операции, где пользователю предлагается
нажать на одну из двух кнопок:

• askyesno()

• askokcancel()

• askretrycancel()

Все эти функции принимают те же три параметра title, message и options. Отличие между ними только в том, что кнопки имеют разный текст. В случае нажатия на кнопку подтверждения, функция возвращает значение True, иначе возвращается False

from tkinter import *
from tkinter import ttk
from tkinter.messagebox import showinfo, askyesno

root = Tk()
root.title("METANIT.COM")
root.geometry("250x200")

def click(): 
    result = askyesno(title="Подтвержение операции", message="Подтвердить операцию?")
    if result: showinfo("Результат", "Операция подтверждена")
    else: showinfo("Результат", "Операция отменена")

ttk.Button(text="Click", command=click).pack(anchor="center", expand=1)

root.mainloop()

В данном случае по нажатию на кнопку вызывается функция askyesno(), которая отображает диалоговое окно с двумя кнопками «Да» и «Нет».
В зависимости от того, на какую кнопку нажмет пользователь, функция возвратит True или False. Получив результат функции, мы можем проверить его и выполнить те или иные действия.

Особняком стоит функция askquestion — она также отображает две кнопки для подтверждения или отмены действия (кнопки «Yes»(Да) и «No»(Нет)),
но в зависимости от нажатой кнопки возвращает строку: «yes» или «no».

Также отдельно стоит функция askyesnocancel() — она отображает три кнопки: Yes (возвращает True), No (возвращает False) и Cancel
(возвращает None):

from tkinter import *
from tkinter import ttk
from tkinter.messagebox import showinfo, askyesnocancel

root = Tk()
root.title("METANIT.COM")
root.geometry("250x200")

def click(): 
    result =  askyesnocancel(title="Подтвержение операции", message="Подтвердить операцию?")
    if result==None: showinfo("Результат", "Операция приостановлена")
    elif result: showinfo("Результат", "Операция подтверждена")
    else : showinfo("Результат", "Операция отменена")

ttk.Button(text="Click", command=click).pack(anchor="center", expand=1)

root.mainloop()

В этом случае диалоговое окно предоставит выбор из трех альтернатив

Настройка окон

Дополнительно все вышерассмотренные функции принимают ряд параметров, которые могут применяться для настройки окон. Некоторые из них:

• detail: дополнительный текст, который отображается под основным сообщением

• icon: иконка, которая отображается рядом с сообщением. Должна представлять одно из втроенных изображений: info, error, question или warning

• default: кнопка по умолчанию. Должна представлять одно из встроенных значений: abort, retry, ignore, ok, cancel, no, yes

from tkinter import *
from tkinter import ttk
from tkinter.messagebox import OK, INFO, showinfo 

root = Tk()
root.title("METANIT.COM")
root.geometry("250x200")

def click(): 
    showinfo(title="METANIT.COM", message="Добро пожаловать на сайт METANIT.COM", 
            detail="Hello World!", icon=INFO, default=OK)

ttk.Button(text="Click", command=click).pack(anchor="center", expand=1)

root.mainloop()

При нажатии на кнопку отобразится следующее окно:

Python tkinter messagebox askquestion

• askquestion prompt is used to ask questions from the user.
• The response can be collected in the ‘Yes‘ or ‘No‘ form.
• This function returns the ‘yes‘ or ‘no‘.
• These return types can be controlled using an if-else statement.
• We will see this in the below example.

Code:

In this Python code, we have implemented the askquestion messagebox. We stored the value of messagebox in a variable ‘res’. Then we have compared the variable with the return type i.e ‘yes’ or ‘no’.

from tkinter import *
from tkinter import messagebox

ws = Tk()
ws.title('Python Guides')
ws.geometry('300x100')

def askMe():
    res = messagebox.askquestion('askquestion', 'Do you like cats?')
    if res == 'yes':
        messagebox.showinfo('Response', 'You like Cats')
    elif res == 'no':
        messagebox.showinfo('Response', 'You must be a dog fan.')
    else:
        messagebox.showwarning('error', 'Something went wrong!')


Button(ws, text='Click here', padx=10, pady=5, command=askMe).pack(pady=20)

ws.mainloop()

Output:

In this output, there is a button which when clicked will prompt with the question. The user will reply in ‘yes’ or ‘no’. accordingly another messagebox will prompt.

Python tkinter messagebox position

• In this section, we will talk about the messagebox position
• This can be achieved using a Toplevel widget.
• any other widget can be placed on a Toplevel widget.
• It is similar to python frames but is specially created for creating customized prompts.
• In the below example we have placed image, label & 2 buttons.
• It will look like a prompt but we can position things as per our requirement.
• for image we have couple of options listed below.
  • ::tk::icons::error
  • ::tk::icons::information
  • ::tk::icons::warning
  • ::tk::icons::question

Code:

Here is a code in Python to create messagebox with customized position of widgets in it. We have placed an icon or image of the question over here. But you can replace it with ‘error’, ‘warning’, ‘question’ or ‘information’

from tkinter import *

def killWin():
	toplevel = Toplevel(ws)

	toplevel.title("Kill window")
	toplevel.geometry("230x100")


	l1=Label(toplevel, image="::tk::icons::question")
	l1.grid(row=0, column=0)
	l2=Label(toplevel,text="Are you sure you want to Quit")
	l2.grid(row=0, column=1, columnspan=3)

	b1=Button(toplevel,text="Yes",command=ws.destroy, width=10)

Python tkinter yes no dialog box

Let us see, how to generate Yes or No Popups in Python Tkinter or Python tkinter yes no message box. Python Tkinter provides a messagebox module that allows generating Yes and No prompts.

• Yes or No Popups are used to ask for confirmation before performing a task. It is mainly used to make sure that the user has not accidentally triggered a task.
• Yes or No prompts can be seen while the user is about to exit the program or while he is about to initiate any sensitive task. for example, while transferring money you see a prompt “Do you want to Proceed”.
• There are two functions inside the messagbox module that are used to generate Yes or No Prompts:
  • messagebox.askquestion()
  • messagebox.askyesno()
• messagebox.askquestion() function is used to ask a question from the user and the user has to reply in yes or no. The function returns True when the user clicks on the Yes button and Flase when the user clicks on the No button.
• messagebox.askyesno() function also does the same thing that it asks the user to reply in yes or no. The function returns True for yes and False for no.
• We have a complete section on Python Tkinter messagebox with an example. In this, we have covered all the available options for message box.

Syntax:

• Here is the syntax of the messagebox in Python Tkinter. In the first line, we have imported the messagebox module from the Tkinter library.
• In the second line, the option is the function that will generate a prompt. There are seven options to generate the prompt but in this tutorial, we’ll discuss only two of them:
  • messagebox.askquestion()
  • messagebox.askyesno()

from tkinter import messagebox

messagebox.option('title', 'message_to_be_displayed')

Example of Yes No popups in Python Tkinter

• This application shows two options to the user. One is to donate & another one is to Exit the application.
• If the user clicks on the transfer button, askquestion() function is triggered & it requests the user for confirmation.
• if the user clicks on the Exit button, askyesno() function is triggered and it asks the user if he is sure to exit the application.

from tkinter import *
from tkinter import messagebox

ws = Tk()
ws.title('PythonGuides')
ws.geometry('400x300')
ws.config(bg='#4a7a8c')

def askQuestion():
    reply = messagebox.askyesno('confirmation', 'Are you sure you want to donate $10000 ?')
    if reply == True:
        messagebox.showinfo('successful','You are the Best!')
    else:
        messagebox.showinfo('', 'Maybe next time!')
       

def askYesNo():
    reply = messagebox.askyesno('confirmation', 'Do you want to quit this application?')
    if reply == True:
        messagebox.showinfo('exiting..', 'exiting application')
        ws.destroy()
    else:
        messagebox.showinfo('', 'Thanks for Staying')
       

btn1 = Button(
    ws,
    text='Transfer',
    command=askQuestion,
    padx=15,
    pady=5
)
btn1.pack(expand=True, side=LEFT)

btn2 = Button(
    ws,
    text='Exit',
    command=askYesNo,
    padx=20,
    pady=5
)
btn2.pack(expand=True, side=RIGHT)

ws.mainloop()

Output of the above code

Here is the output of the above code, In this code user wants to exit the application. He sees Yes No popup after clicking on the exit button.

Python Tkinter dialog window

In this section, we will learn how to create a dialog window in Python Tkinter.

A dialog window is used to communicate between the user and the software program or we can also say that it is simply used to display the message and require acknowledgment from the user.

Code:

In the following code, we import the library Simpledialog which is used for creating a dialog window to get the value from the user.

• simpledialog.askinteger() is used to get an integer from the user.
• simpledialog.askstring() is used to get a string value from the user.
• simpledialog.askfloat() is used to get a float value from the user.

from tkinter import *
from tkinter import simpledialog

ws = Tk()
ws.title("Python Guides")

answer1 = simpledialog.askstring("Input", "What is your first name?",
                                parent=ws)
if answer1 is not None:
    print("Your first name is ", answer1)
else:
    print("You don't have a first name?")

answer1 = simpledialog.askinteger("Input", "What is your age?",
                                 parent=ws,
                                 minvalue=0, maxvalue=100)
if answer1 is not None:
    print("Your age is ", answer1)
else:
    print("You don't have an age?")

answer1 = simpledialog.askfloat("Input", "What is your salary?",
                               parent=ws,
                               minvalue=0.0, maxvalue=100000.0)
if answer1 is not None:
    print("Your salary is ", answer1)
else:
    print("You don't have a salary?")
ws.mainloop()

Output:

After running the above code we get the following output in which we see a dialog window in which users enter their names. After entering the name click on ok.

After clicking on ok next dialog window will open in which the user can enter their name. After entering their age click on OK.

After clicking on ok next dialog window will open where the user can enter their salary and finally click on ok.

After clicking on ok the overall data will show on the command prompt.

Python Tkinter dialog yes no

In this section, we will learn how to create a yes or no dialog box in Python Tkinter.

This is an alert dialog box in which users can choose they want to continue or quit. if the user wants to quit click on the Yes if they don’t want to quit click on No.

Output:

In the following code, we import tkinter.messagebox library for giving the alert message yes and no. We also create a window and giving the title “Python Guides” to the window on which a yes or no pop-up message will show.

askyesno()function to show a dialog that asks for user confirmation.

from tkinter import *
from tkinter.messagebox import askyesno

# create the root window
ws = Tk()
ws.title('Python Guides')
ws.geometry('200x200')

# click event handler
def confirm():
    answer = askyesno(title='confirmation',
                    message='Are you sure that you want to quit?')
    if answer:
        ws.destroy()


Button(
    ws,
    text='Ask Yes/No',
    command=confirm).pack(expand=True)


# start the app
ws.mainloop()

Output:

In the following output, we see the window on which a yes or no pop-up message will show.

After clicking on Ask yes/No the confirmation message will show “Are you sure that you want to quit?” with the yes and No buttons. On clicking on yes all the programs will quit otherwise they stay on the first window.

Python Tkinter open path using the dialog window

In this section, we will learn how to create an open path using the dialog box in Python Tkinter.

The open dialog allows the user to specify the drive, directory, and the name of the file to open.

Code:

In the following code, we import library filedialog as fd and also create window ws= Tk() with the title “Python Guides”.

• fd.askopenfilename() function return the file name we selected and also support other function that displayed by dialog.
• error_msg = It show the error msg when file is not supported.
• Button() can display the text or images.

from tkinter import *
from tkinter import filedialog as fd 
ws = Tk()
ws.title("Python Guides")
ws.geometry("100x100")
def callback():
    name= fd.askopenfilename() 
    print(name)
    
error_msg = 'Error!'
Button(text='File Open', 
       command=callback).pack(fill=X)
ws.mainloop()

Output:

In the following output we see a window inside the window we add a button with the name“File Open”.

After clicking the button a dialog box is open. Select the file name after selecting click on the open button.

After clicking on the open button the file path and location is shown on the command prompt as shown in this image.

Python Tkinter dialog return value

In this section, we will learn how to create a dialog return value in python Tkinter.

The return value is something when the user enters the number in a dialog. And the number entered by the user is displayed on the main window as a return value.

Code:

In the following code, we create a window ws = TK() inside the window we add a button with the text “Get Input”. We also create labels and entries for taking the input from the user.

• Label() function is used as a display box where the user can place text.
• Button() is used for submitting the text.
• customdialog() is used to get the pop-up message on the main window.

from tkinter import *

    ws = Tk()
    ws.title("Python Guides")
    ws.geometry("200x200")
    example(ws).pack(fill="both", expand=True)
    ws.mainloop()

Output:

After running the above code we get the following output in this we create a window inside the window we add a button with the title “Get Input”.

After clicking on the “Get Input” button we get a dialog box. Inside the dialog box user can enter anything. After entering input click on the OK button.

After clicking on the ok button we get the return value on the main window.

Python Tkinter dialog modal

In this section, we will learn how to create a dialog modal in Python Tkinter.

The modal window creates a way that damages the main window but makes it visible with the modal window. We can use the modal window as the main window. This is design for computer applications.

Code:

In the following code, we import .ttk import Style library for giving the style to the window. Here we create a window inside the window we add some labels and buttons.

• Label()function is used as a display box where the user can place text.
• Button()function is used when the user is pressed a button by a mouse click some action is started.
• Pop.destroy() is used for destroying the window after use.

from tkinter import *
from tkinter.ttk import Style

ws = Tk()
ws.title("Python Guides")

ws.geometry("200x250")
style = Style()
style.theme_use('clam')

def choice1(option):
   pop1.destroy()
   if option == "yes":
      label1.config(text="Hello, How are You?")
   else:
      label1.config(text="You have selected No")
      ws.destroy()
def click_fun1():
   global pop1
   pop1 = Toplevel(ws)
   pop1.title("Confirmation")
   pop1.geometry("300x150")
   pop1.config(bg="white")

   label1 = Label(pop1, text="Would You like to Proceed?",
   font=('Aerial', 12))
   label1.pack(pady=20)

   frame1 = Frame(pop1, bg="gray71")
   frame1.pack(pady=10)
   
   button_1 = Button(frame1, text="Yes", command=lambda: choice1("yes"), bg="blue", fg="black")
   button_1.grid(row=0, column=1)
   button_2 = Button(frame1, text="No", command=lambda: choice1("no"), bg="blue", fg="black")
   button_2.grid(row=0, column=2)

label1 = Label(ws, text="", font=('Aerial', 14))
label1.pack(pady=40)

Button(ws, text="Click Here", command=click_fun1).pack()

ws.mainloop()

Output:

In the following output, we see a window inside the window a button is placed. By clicking on the “Click Here” button some action is started and move to the next command.

After click on the “Click Here” button, the confirmation window is open with the text “Would You Like to Proceed” if yes click on yes if no click on.

After click on the yes button, we see some text is showing o the main window.

Python Tkinter dialog focus

In this section, we will learn how to create a dialog focus in Python Tkinter.

Before moving forward we should have a piece of knowledge about focus. Focus is that to giving attention to a particular thing or we can say that a center point of all the activity.

Dialog focus is when the user enters some input into a dialog box and wants to move forward then they click on the button so there completely focus on the button.

Code:

In the following code, we create a window inside the window we create an entry widget and buttons. Button widget which complete has the focus.

• Entry()is used for giving input from the user.
• Button() function is used when the user is pressed a button by a mouse click some action is started.

from tkinter import *
from tkinter.ttk import *

ws = Tk()
ws.title("Python Guides")

entry1 = Entry(ws)
entry1.pack(expand = 1, fill = BOTH)

entry2 = Button(ws, text ="Button")

entry2.focus_set()
entry2.pack(pady = 5)

entry3 = Radiobutton(ws, text ="Hello")
entry3.pack(pady = 5)

ws.mainloop()

Output:

Here is a dialog widget in which the user enters the input and future proceeding they click on the button. In this the button widget completely has focus.

So, in this tutorial, we discussed Python Tkinter Dialog Box Window and we have also covered different examples.

In this section, we will learn about how to create a Popup message in Python Tkinter.

Before moving forward we should have a piece of knowledge about Popup. Popup is defined as notification that occurs suddenly and catches the audience’s attention. Popup message occurs on the user window.

Code:

In the following code, we create a window inside the window we also create a button with the text “Click Me”. After clicking on them a Popup window will be open.

import tkinter.messagebox importing this library for showing the message on the Popup screen.

tkinter.messagebox.showinfo() is used for displaying the important information.

from tkinter import *

import tkinter.messagebox

ws = Tk()

ws.title("Python Guides")
ws.geometry("500x300")

def on_Click():
	tkinter.messagebox.showinfo("Python Guides", "Welcome")


but = Button(ws, text="Click Me", command=on_Click)

but.pack(pady=80)
ws.mainloop() 

Output:

In the following output, we see a window inside the window a button is placed.

By clicking on this button a Popup window is generated which shows some message.

In this following section, we will learn how to create a Popup input box in Python Tkinter.

Inputbox is where the user can enter some value, text after entering there is a button to move forward to complete the task. The Popup input box is similar where the user can insert the text when the pop input box window will appear.

Code:

In the following code, we create a window inside the window we add a label and button. We also define a Popup input window as Popup_win inside this window we create an entry where we can insert some text.

from tkinter import*

ws= Tk()
ws.title("Python Guides")

ws.geometry("500x300")

def closewin(tp):
   tp.destroy()
def insert_val(e):
   e.insert(0, "Hello Guides!")

def popup_win():
  
   tp= Toplevel(ws)
   tp.geometry("500x200")
   
   entry1= Entry(tp, width= 20)
   entry1.pack()

   Button(tp,text= "Place text", command= lambda:insert_val(entry1)).pack(pady= 5,side=TOP)
   
   button1= Button(tp, text="ok", command=lambda:closewin(tp))
   button1.pack(pady=5, side= TOP)

label1= Label(ws, text="Press the Button to Open the popup dialogue", font= ('Helvetica 15 bold'))
label1.pack(pady=20)

button1= Button(ws, text= "Press!", command= popup_win, font= ('Helvetica 16 bold'))
button1.pack(pady=20)
ws.mainloop()

Output:

In the following output, we see a label and button present on the window where the label is used to describe the task and the button is used for continuing the task.

On the clicking, the Press button a Popup input box is shown on the screen where we can insert some text in the input box on clicking on the place text button. After inserting click on the ok button.

In the following section, we will learn how to create a Popup dialog in Python Tkinter.

The Popup dialog box is similar to the popup message this is shown on top of the existing window.

Code:

In the following code, we see a window inside the window buttons are placed on clicking on any of these buttons a Popup dialog box appear on the screen.

from tkinter import *

import tkinter.messagebox

ws = Tk()

ws.title("Python Guides")
ws.geometry('500x300')

def Eastside():
	tkinter.messagebox.showinfo("Python Guides", "Right button Clicked")

def Westside():
	tkinter.messagebox.showinfo("Python Guides", "Left button Clicked")

def Northside():
	tkinter.messagebox.showinfo("Python Guides", "Top button Clicked")

def Southside():
	tkinter.messagebox.showinfo("Python Guides", "Bottom button Clicked")

button1 = Button(ws, text="Left", command=Westside, pady=10)
button2 = Button(ws, text="Right", command=Eastside, pady=10)
button3 = Button(ws, text="Top", command=Northside, pady=10)
button4 = Button(ws, text="Bottom", command=Southside, pady=10)

button1.pack(side=LEFT)
button2.pack(side=RIGHT)
button3.pack(side=TOP)
button4.pack(side=BOTTOM)

ws.mainloop()

Output:

After running the above code we get the following output in which we see four buttons Paced at “Top”, “Bottom”, “Left”, “Right” inside the window.

On clicking on the Top button a Popup dialog open with the message“Top button

In this section, we will learn how to create a Popup menu in Python Tkinter.

The Popup menu appears on the main window by right-clicking on the main window. A menu bar is Popup on the screen with limited choices.

Code:

In the following code, we create a window inside the window we add a label with the text “Right-click To Display a Menu”.As the label describes what to do as the menu bar is Popup on the screen.

• Menu() is used to display the menubar on the screen.
• pop_up.add_command()is used to add some command in the menubar.

from tkinter import *

ws = Tk()
ws.title("Python Guides")

ws.geometry("500x300")

label1 = Label(ws, text="Right-click To Display a Menu", font= ('Helvetica 16'))
label1.pack(pady= 40)

pop_up = Menu(ws, tearoff=0)

pop_up.add_command(label="New")
pop_up.add_command(label="Edit")
pop_up.add_separator()
pop_up.add_command(label="Save")

def menupopup(event):
   
   try:
      pop_up.tk_popup(event.x_root, event.y_root, 0)
   finally:
      
      pop_up.grab_release()

ws.bind("<Button-3>", menupopup)

button1 = Button(ws, text="Exit", command=ws.destroy,width=6,height=4)
button1.pack()

ws.mainloop()

Output:

In the following output, as we see there is a label and button place inside the window.

When we right-click anywhere on the window menubar is a popup on the window.

In this section, we will learn how we can create close the popup window in Python Tkinter.

In the close popup window, we want to close the window that is currently Popup on the screen.

Code:

In the following code, we import tkinter.messagebox library for showing the message on the popup window and want to close this window with a show warning message.

• tkinter.messagebox.askyesno() is used for taking the user response if they want to quit click on yes if no click on no.
• tkinter.messagebox.showwarning() is used for showing the warning for verifying the user response.
• tkinter.messagebox.showinfo() is used for showing the information that the POPup window is closed.

from tkinter import *
import tkinter.messagebox 

ws=Tk()
ws.title("Python Guides")
ws.geometry("300x200")


def callfun():
    if tkinter.messagebox.askyesno('Python Guides', 'Really quit'):
        tkinter.messagebox.showwarning('Python Guides','Close this window')
    else:
        tkinter.messagebox.showinfo('Python Guides', 'Quit has been cancelled')

Button(text='Close', command=callfun).pack(fill=X)

ws.mainloop()

Output:

In the following output er see a window inside a window a button is placed on clicking on them we get askyesno message.

As shown in this picture we choose the option yes or no if we want to close the popup window then click on yes.

After clicking on yes we see this popup window come on the screen by click on the ok button they close the popup window.
