Let us suppose we have created an oval on a Tkinter canvas. The task is to change the thickness of the oval's outline. To change the thickness of the outline, provide a border or outline to a rectangle, define the width property in the constructor and assign it an integer value. You can also define the outline property to set a color to the outline of the oval.
Example
#Import the required libraries from tkinter import * #Create an instance of Tkinter Frame win = Tk() #Set the geometry win.geometry("700x350") # Define a Canvas Widget canvas = Canvas(win, width=500, height=350) canvas.pack() # Create an oval in Canvas canvas.create_oval(100,300,500,100, outline='green', width=5) win.mainloop()
Output
Running the above code will display a window containing an oval with a thick green outline.
