How to put an outline on a canvas text on Tkinter?

Tkinter Canvas widget can be used for many purposes such as adding images, creating and drawing shapes in the canvas, animating the shapes and objects, etc. Using the Canvas inbuilt functions and methods, we can create and display the text.

To create a text, we use create_text(x,y, text, **options) method. To add an outline around the text in Canvas, we have to create the bounding box around the text. The bounding box property links the invisible box with the widget. And, this will allow us to put a rectangle in the text.

Once we have created a rectangle, we can pull this behind and make the text above the rectangle. The rectangle must be given an outline property that surrounds the canvas item.

Example

# Import the required libraries
from tkinter import *

# Create an instance of tkinter frame or window
win=Tk()

# Set the size of the window
win.geometry("700x350")

# Create a canvas widget
canvas=Canvas(win, bg="blue3")
canvas.pack()

# Create a text in canvas
text=canvas.create_text(100,200, text="This works only in canvas",
font=('Calibri 18'), anchor="w", fill="white")

# Make the bounding-box around text
bbox=canvas.bbox(text)

# Create a rectangle inside the bounding box
rect=canvas.create_rectangle(bbox, outline="yellow",
fill="black", width=5)

# Make the text above to the rectangle
canvas.tag_raise(text,rect)

win.mainloop()
