Canvas<\/h2>\n

Let’s take a look at Canvas. With this widget you can draw something on the window. The first thing that we are going to look at is how to create the canvas itself and then how to draw a rectangle in it.

Create the Canvas widget<\/h2>\n

As usual, we create the window.<\/p>\n

# window\r\n\r\nimport tkinter as tk\r\n\r\nroot = tk.Tk()\r\n\r\nroot.mainloop()<\/pre>\n
And then we add the canvas widget:<\/p>\n
# window\r\n\r\nimport tkinter as tk\r\n\r\nroot = tk.Tk()\r\n\r\ncanvas = tk.Canvas(root, width=400, height=400)\r\ncanvas.pack()\r\n\r\nroot.mainloop()<\/pre>\n
Now we can draw a rectangle on the canvas, with a code like this:<\/p>\n
# drawing a rectangle\r\n\r\n# the arguments are coordinates of top left and bottom right vertex\r\n# you give the rectangle a color with the fill parameter\r\ncanvas.create_rectangle(10, 10, 100, 100, fill='blue')<\/pre>\n
In the next paragraph, we will see an application of this code to draw rectangles where we click the mouse button.<\/p>\n
