### Message Widget

The widget can be used to display short text messages. The message widget is similar in its functionality to the Label widget, but it is more flexible in displaying text, e.g. the font can be changed while the Label widget can only display text in a single font. It provides a multiline object, that is the text may span more than one line. The text is automatically broken into lines and justified. We were ambiguous, when we said, that the font of the message widget can be changed. This means that we can choose arbitrarily a font for one widget, but the text of this widget will be rendered solely in this font. This means that we can't change the font within a widget. So it's not possible to have a text in more than one font. If you need to display text in multiple fonts, we suggest to use a Text widget.

The syntax of a message widget:

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

Let's have a look at a simple example. The following script creates a message with a famous saying by Mahatma Gandhi:

import tkinter as tk
master = tk.Tk()
whatever_you_do = "Whatever you do will be insignificant, but it is very important that you do it.\n(Mahatma Gandhi)"
msg = tk.Message(master, text = whatever_you_do)
msg.config(bg='lightgreen', font=('times', 24, 'italic'))
msg.pack()
tk.mainloop()


The widget created by the script above looks like this:

### The Options in Detail

Option Meaning
anchor The position, where the text should be placed in the message widget: N, NE, E, SE, S, SW, W, NW, or CENTER. The Default is CENTER.
aspect Aspect ratio, given as the width/height relation in percent. The default is 150, which means that the message will be 50% wider than it is high. Note that if the width is explicitly set, this option is ignored.
background The background color of the message widget. The default value is system specific.
bg Short for background.
borderwidth Border width. Default value is 2.
bd Short for borderwidth.
cursor Defines the kind of cursor to show when the mouse is moved over the message widget. By default the standard cursor is used.
font Message font. The default value is system specific.
foreground Text color. The default value is system specific.
fg Same as foreground.
highlightbackground Together with highlightcolor and highlightthickness, this option controls how to draw the highlight region.
highlightcolor See highlightbackground.
highlightthickness See highlightbackground.
justify Defines how to align multiple lines of text. Use LEFT, RIGHT, or CENTER. Note that to position the text inside the widget, use the anchor option. Default is LEFT.
