from tkinter import * class Root(Tk): def __init__(self): super(Root, self).__init__() # Set title of the window self.title("Codeloop.org - Tkinter Canvas") # Set window icon self.iconphoto(True, PhotoImage(file='codeloop.png')) # Call method to create the canvas widget self.canvasWidget() def canvasWidget(self): # Create Canvas widget with blue background canvas = Canvas(self, bg="blue", height=250, width=300) # Define coordinates for an arc inside the Canvas coord = 10, 50, 240, 210 # Create an arc shape inside the Canvas arc = canvas.create_arc(coord, start=0, extent=150, fill="red") # Pack the Canvas widget into the window canvas.pack() # Create an instance of the Root class root = Root() root.mainloop() |
Now let’s describe the code:
Imports:
- We import the tkinter module to access its classes and functions.

from tkinter import * |
TKinter Root Class:
- We have defined a class Root that inherits from Tk, and it represents the main window of our Tkinter application.
- __init__ method initializes the window with a title and icon, then calls the canvasWidget method.

class Root(Tk): def __init__(self): super(Root, self).__init__() ... |
canvasWidget Method:
- This method creates a Canvas widget with specific attributes:
- Background color: blue
- Height: 250 pixels
- Width: 300 pixels
- It defines coordinates for an arc shape inside the Canvas.
- An arc shape is created inside the Canvas using specific coordinates, start angle, extent, and fill color.
- The Canvas widget is packed into the window.

def canvasWidget(self): ... |
Creating Application Instance and Running the Event Loop:
- An instance of the Root class is created.
- The Tkinter event loop is started (root.mainloop()), which listens for events such as button clicks and updates the GUI accordingly.
