draw_point

← All Python Programs

Aim:

☛   Write a function called draw_point that takes a Canvas and a Point as arguments and draws a representation of the Point on the Canvas.

Solution :


PROGRAM: (draw_point.py) 

 
from tkinter import *
# Create an instance of tkinter frame or window
win = Tk ()
# Create Title
win.title(" Draw - point ")
# Set the size of the window
win.geometry("700x350")
# Define a function to draw the line between two points
def draw_point(event):
	x1= event.x
	y1= event.y
	x2= event.x
	y2= event.y
	# Draw an oval in the given co-ordinates
	canvas.create_oval(x1,y1,x2,y2,fill="black",width = 20 )
# Create a canvas widget
canvas = Canvas(win,width = 650,height = 300,background = "white")
canvas.grid(row = 0 ,column = 0)
canvas.bind('<Button-1>',draw_point)
click_num = 0
win.mainloop()
