Python Tkinter | Create different shapes using Canvas class

Last Updated : 25 Jun, 2019

In Tkinter, Canvas class is used to create different shapes with the help of some functions which are defined under Canvas class. Any shape that Canvas class creates requires a canvas, so before creating any shapes a Canvas object is required and needs to be packed to the main window.

Canvas Methods for shapes:

Canvas.create_oval(x1, y1, x2, y2, options = …): It is used to create a oval, pieslice and chord.
Canvas.create_rectangle(x1, y1, x2, y2, options = …): It is used to create rectangle and square.
Canvas.create_arc(x1, y1, x2, y2, options = …) This is used to create an arc.
Canvas.create_polygon(coordinates, options = …) THis is used to create any valid shapes.

We are using a class to show the working of functions that helps to creates different shapes.

Class parameters –

Data members used: master, canvas

Member functions used: create() method

Widgets used: Canvas

Tkinter method used:
Canvas.create_oval()
Canvas.create_rectangle()
Canvas.create_arc()
Canvas.create_polygon()
pack()
title()
geometry()

Below is the Python code –

# Imports each and every method and class 
# of module tkinter and tkinter.ttk 
from tkinter import * from tkinter.ttk import * class Shape: 
    def __init__(self, master = None): 
        self.master = master 
          
        # Calls create method of class Shape 
        self.create() 
      
    def create(self): 
          
        # Creates a object of class canvas 
        # with the help of this we can create different shapes 
        self.canvas = Canvas(self.master) 
  
        # Creates a circle of diameter 80 
        self.canvas.create_oval(10, 10, 80, 80,  
                            outline = "black", fill = "white", 
                            width = 2) 
          
        # Creates an ellipse with horizontal diameter 
        # of 210 and vertical diameter of 80 
        self.canvas.create_oval(110, 10, 210, 80, 
                            outline = "red", fill = "green", 
                            width = 2) 
          
        # Creates a rectangle of 50x60 (heightxwidth) 
        self.canvas.create_rectangle(230, 10, 290, 60, 
                                outline = "black", fill = "blue", 
                                width = 2) 
          
        # Creates an arc of 210 deg 
        self.canvas.create_arc(30, 200, 90, 100, start = 0, 
                          extent = 210, outline = "green", 
                          fill = "red", width = 2) 
          
        points = [150, 100, 200, 120, 240, 180, 
                  210, 200, 150, 150, 100, 200] 
          
        # Creates a polygon 
        self.canvas.create_polygon(points, outline = "blue", 
                              fill = "orange", width = 2) 
        # Pack the canvas to the main window and make it expandable 
        self.canvas.pack(fill = BOTH, expand = 1) 
  
if __name__ == "__main__": 
      
    # object of class Tk, resposible for creating 
    # a tkinter toplevel window 
    master = Tk() 
    shape = Shape(master) 
  
    # Sets the title to Shapes 
    master.title("Shapes") 
  
    # Sets the geometry and position 
    # of window on the screen 
    master.geometry("330x220 + 300 + 300") 
  
    # Infnite loop breaks only by interrupt 
    mainloop()
