Dialog Boxes with Python

Dialog boxes are a commonly used GUI element to provide feedback to the user and also to prompt the user for information or to take an action. Some examples of common dialogs are:

• A simple message: «Press OK to continue»
• Ask for «OK or cancel»
• Ask for «Yes, no or cancel»

We will look at several different methods for creating dialog boxes in Python including cross-platform options like tkinter and PyAutoGUI, as well as a couple Windows specific options.

Using PyAutoGUI (cross-platform)

This is the method I recommend as it is the simplest to use. It is also the most limited option though. PyAutoGUI uses tkinter under the hood, but provides a nice interface.

# python -m pip install pyautogui import pyautogui # Examples: pyautogui.alert('Just a notification', "Title") # always returns "OK" pyautogui.confirm('Asks OK or Cancel') # returns "OK" or "Cancel" pyautogui.prompt('Asks for a string from user') # returns string or None pyautogui.password('Enter password') # returns string or None # Method signatures: # alert(text='', title='', button='OK') # confirm(text='', title='', buttons=['OK', 'Cancel']) # prompt(text='', title='' , default='') # password(text='', title='', default='', mask='*') 

Using tkinter (cross-platform)

Tkinter is a cross-platform library. It comes with most Python installations and it works on Windows, Mac, and Linux.

If you want to learn more about the larget tkinter framework, check out my tutorial on GUI Programming with Python tkinter.

You may need to install the tkinter packages in Ubuntu with:

sudo apt install python-tk python3-tk 

# sudo apt install python-tk python3-tk from tkinter import messagebox # Python 3 # import tkMessageBox as messagebox # Python 2 messagebox.showinfo("Title", "message") 

Here are a list of messagebox types. They all accept parameters in the format of: messagebox.function(title, message [, options])

messagebox.showinfo() messagebox.showwarning() messagebox.showerror() messagebox.askquestion() messagebox.askokcancel() messagebox.askyesno() messagebox.askretrycancel() 

Using ctypes (Windows only)

This method uses only the Python standard library and the Windows API. It requires no extra Python libraries. This solution came from a Stack Overflow answer.

import ctypes MessageBox = ctypes.windll.user32.MessageBoxW # MessageBoxA in Python2 MessageBox(None, 'Message\nfor\nthe\nuser', 'Window title', 0) 

Using pywin32 (Windows only)

This solution uses pywin32 to interact with the Windows API. You can view the source code for pywin32 on GitHub.

First install the pywin32 Python package dependency:

python -m pip install pywin32 

Here is an example of how to use it:

# python -m pip install pywin32 import win32ui import win32con # constants # A simple notification win32ui.MessageBox("Message", "Title") # A prompt for Yes/No/Cancel response = win32ui.MessageBox("Message", "Title", win32con.MB_YESNOCANCEL) if response == win32con.IDYES: win32ui.MessageBox("You pressed yes") elif response == win32con.IDNO: win32ui.MessageBox("You pressed no") elif response == win32con.IDCANCEL: win32ui.MessageBox("You pressed cancel") 

Check out the full list of constants in win32con. This is where you can find what the potential options for button presses are ( ID* ) and what the different MessageBox types there are ( MB_* ).

# Potential dialog responses IDOK IDCANCEL IDABORT IDRETRY IDIGNORE IDYES IDNO IDCLOSE IDHELP # MessageBox types MB_OK MB_OKCANCEL MB_ABORTRETRYIGNORE MB_YESNOCANCEL MB_YESNO MB_RETRYCANCEL MB_ICONASTERISK MB_ICONERROR 

It’s not the easiest to remember and work with because of all the Windows API interaction, but it’s a decent option.

Conclusion

You should know have a solid grasp on creating dialog boxes to prompt a user for a question or to alert them of some action.

How to Display Alert Message using Python

You can display the alert message with just 2 lines of python code . Let’s move on to an awesome project. Before getting into this, we will have a python interpreter andPyAutoGUI packages. In this case, I will use pycharm IDE. How to install pycharm in windows: https://iterathon.tech//how-to-install-the-pycharm-in-windows/

Open New Projects

After opening a pycharm click on a new project and you can give it any name as an alert message. In this project.

Once you have give the name and click on the create. It takes few seconds to create the project, In the current project (alert message) there are some existing files are found in IDE so, delete all those files using Ctrl+A and Backspace. Now Python is ready to code before that we need one awesome python packages called PyAutoGUI.

Install PyautoGUI

Pyautogui is a library that allows you to control the mouse, keyboard as well as allows you to do various tasks.

Link to PyAutoGUI package: https://pypi.org/project/PyAutoGUI/. After getting into the link. You need to copy the magical word to install pyAutoGUI. That is pip install PyAutoGUI .

Again go to the pycharm and click terminal then paste the magical word pip install PyAutoGUI. It takes few seconds to install packages. Once the package gets installed and then go to your project alert message.

Code

This is an easy and crazy python project to display alerts messages . Let’s further move on to the python program.

# python code for display alert messages import pyautogui pyautogui.alert("Always be with Iterathon") #Output

Therefore, you run this code, the alert message pops up in the center of the window. then click ok. finally, that popup box get disappears. Suppose if you give more than one alert message, it will execute one by one.

tkinter.messagebox — Tkinter message prompts¶

The tkinter.messagebox module provides a template base class as well as a variety of convenience methods for commonly used configurations. The message boxes are modal and will return a subset of (True, False, OK, None, Yes, No) based on the user’s selection. Common message box styles and layouts include but are not limited to:

class tkinter.messagebox. Message ( master = None , ** options ) ¶

Create a default information message box.

Information message box

tkinter.messagebox. showinfo ( title = None , message = None , ** options ) ¶

Warning message boxes

tkinter.messagebox. showwarning ( title = None , message = None , ** options ) ¶ tkinter.messagebox. showerror ( title = None , message = None , ** options ) ¶

Question message boxes

tkinter.messagebox. askquestion ( title = None , message = None , ** options ) ¶ tkinter.messagebox. askokcancel ( title = None , message = None , ** options ) ¶ tkinter.messagebox. askretrycancel ( title = None , message = None , ** options ) ¶ tkinter.messagebox. askyesno ( title = None , message = None , ** options ) ¶ tkinter.messagebox. askyesnocancel ( title = None , message = None , ** options ) ¶
