We want to write an application for painting or writing into a canvas.
from tkinter import *
canvas_width = 300
canvas_height = 300
def paint( event ):
python_green = "#476042"
x1, y1 = ( event.x - 1 ), ( event.y - 1 )
x2, y2 = ( event.x + 1 ), ( event.y + 1 )
w.create_oval( x1, y1, x2, y2, fill = python_green )
master = Tk()
master.title( "Painting using Ovals" )
w = Canvas(master,
width=canvas_width,
height=canvas_height)
w.pack(expand = YES, fill = BOTH)
w.bind( "<B1-Motion>", paint )
message = Label( master, text = "Press and Drag the mouse to draw" )
message.pack( side = BOTTOM )
mainloop()
