CustomTkinter Messagebox 2

CustomTkinter Messagebox 2 is an implementation of the tkinter.messagebox functionalities using the customtkinter package. It replicates the same functions available in tkinter.messagebox, but with support for CustomTkinter's modernized interface.

Optimal widgets size proportion, better UX, easy to use and does not require configuration.

It allows the user to copy the message to the clipboard.

Features

This package offers the following functionalities, replicating the behavior of tkinter.messagebox:

There are 8 different message box types:

• showinfo: Displays a dialog with an informational message.
• showwarning: Displays a dialog with a warning message.
• showerror: Displays a dialog with an error message.
• askquestion: Displays a question and returns the user's response (Yes/No).
• askokcancel: Displays a question and returns OK or Cancel.
• askyesno: Displays a question and returns Yes or No.
• askretrycancel: Displays an error message and asks the user to choose Retry or Cancel.

The window size is self adjustable according to the number of lines in the message. Messages will also be displayed with a scrollbar if they are bigger than the message box window.

The main code will stop and wait for the message box to be closed and the function returns a value related to the button clicked:

• showinfo(master, title:str, message:str)
• showsuccess(master, title:str, message:str)
• showwarning(master, title:str, message:str)
• showerror(master, title:str, message:str)
• askokcancel(master, title:str, message:str)
• askyesno(master, title:str, message:str)
• askyesnocancel(master, title:str, message:str)
• askretrycancel(master, title:str, message:str)
• showcustom(master, title:str, message:str, icon:str, *buttons:[str])

Icons

There are 5 icons designed for this package and are free to use and redistribute. Icons variables:

ERROR = "icons/error-icon.png"
INFO = "icons/info-icon.png"
QUESTION = "icons/ask-icon.png"
WARNING = "icons/alert-icon.png"
SUCCESS = "icons/ok-icon.png"

Installation

Install the package via pip:

pip install ctkmessagebox2

Project Structure

The project follows the same functional structure as tkinter.messagebox, allowing easy migration of code and adaptation to more modern interfaces with customtkinter.

Unlikely Tkinter messagebox, ctkmessagebox requires the master as the first argument for all messages.

Usage

All functions share the same structure, with 3 arguments: master: ctk.CTk, title: str and message: str. All the rest is done by the package.

Here’s a basic example of how to use the CustomTkinter Messagebox:

import customtkinter as ctk
import ctkmessagebox2 as messagebox

app = ctk.CTk()
app.geometry("400x200")


def show_info():
    result = messagebox.showinfo(app, "Information", "This is an informational message.")
    print("Clicked Button: ", result)


button = ctk.CTkButton(app, text="Show Info", command=show_info)
button.pack(pady=20)

app.mainloop()

Complete example that allows you to test all message boxes available:

import customtkinter as ctk
import ctkmessagebox2 as messagebox

class AppTest(ctk.CTk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.minsize(400, 200)
        self.title("CTkMessageBox 2 Demo")

        buttons = ctk.CTkFrame(self)
        buttons.pack(side=ctk.LEFT)
        self.button_1 = ctk.CTkButton(buttons, text="showinfo", command=self.showinfo)
        self.button_2 = ctk.CTkButton(buttons, text="showsuccess", command=self.showsuccess)
        self.button_3 = ctk.CTkButton(buttons, text="showwarning", command=self.showwarning)
        self.button_4 = ctk.CTkButton(buttons, text="showerror", command=self.showerror)
        self.button_5 = ctk.CTkButton(buttons, text="askokcancel", command=self.askokcancel)

        self.button_10 = ctk.CTkButton(buttons, text="custom", command=self.custom)

The example above is included in the package, and you can run it from the terminal using the command:
