from tkinter import * from tkinter import ttk from tkinter import messagebox as msg class Root(Tk): def __init__(self): super(Root, self).__init__() self.title("Codeloop.org - Tkinter MessageBox") # Set window icon self.iconphoto(True, PhotoImage(file='codeloop.png')) self.create_button() def create_button(self): # Create button widget self.btn = ttk.Button(self, text="Open Messagebox", command=self.show_error) self.btn.grid(column=0, row=0) def show_message_box(self): # Show information message box msg.showinfo("Python Message Info Box", "Python GUI Created Using Tkinter") def show_warning(self): # Show warning message box msg.showwarning("Warning Message Box", "This Is A Warning Message Box") def show_error(self): # Show error message box msg.showerror("Error Message Box", "This Is An Error Message Box") # Create an instance of the Root root = Root() root.mainloop() |
This code creates a simple Tkinter GUI application with a button, when we click the button, it opens a messagebox displaying an error message. Thisis a breakdown of what the code does:
- Import necessary modules from Tkinter library.
- Define a class Root that inherits from Tk, and it represents the main window of the application.
- In the Root class:
- __init__ method initializes the window with a title and sets an icon for the window.
- create_button method creates a button widget and places it in the window.
- show_message_box, show_warning, and show_error methods display different types of message boxes (information, warning, and error).
- Create an instance of the Root class.
- Start the Tkinter event loop (mainloop() method), and it listens for events like button clicks and updates the GUI accordingly.
When you run this code, it will display a window with a button labeled “Open Messagebox”. When you click this button, it will trigger show_error method, which opens a messagebox, and it displays an error message.
