Python Tkinter Message Widget

Hello dear readers! welcome back to another section of our tutorial on Python. In this tutorial post, we are going to be discussing about Python Tkinter Message Widget.

The Python Tkinter Message widget provides a multiline and noneditable object that displays texts to the screen, automatically breaking lines and justifying their contents.

It has a functionality very similar to the one provided by Label widget, except for the fact that it can also automatically wrap up the text, thus maintaining a given width or aspect ratio.

Syntax

The following below is the syntax for create this widget -

w = Message ( master, option, ... )

Parameter Details

• master - This represents the parent window.

• options - Following below is the list of commonly used options for this widget. These options can be used as key-value pairs that are separated by commas.
