Tkinter Message Widget: Displaying In-App Text

import tkinter as tk
my_w = tk.Tk() # Parent window 
my_w.geometry("620x300")  # Size of the window 
my_w.title("www.plus2net.com")  # Adding a title
font1=['Arial',52,'normal'] # Higher size font 

msg1=tk.Message(my_w,text='Welcome to plus2net tkinter section',
                font=font1,bg='lightgreen',aspect=200)
msg1.grid(row=1,column=1,padx=40,pady=15) 

my_w.mainloop()  # Keep the window open

Using the Tkinter Message Widget for Dynamic Help Messages 🔝

The Message widget in Tkinter displays dynamic help messages that update the text as the user navigates through different input fields.

The widget maintains a fixed size; it automatically adjusts the text line breaks to fit varying message lengths.

This functionality is controlled by event handlers linked to the input widgets, ensuring the displayed text updates appropriately.

import tkinter as tk
my_w = tk.Tk() # Parent window 
my_w.geometry("600x300")  # Size of the window 
my_w.title("www.plus2net.com")  # Adding a title
font1=['Arial',22,'normal'] # Higher size font 
font2=['Arial',18,'normal'] # Higher size font 
my_w.columnconfigure(4,weight=1) # to fix size of Message box
