[Tutor] Traffic Light

[anthonym]

Sure thing.  Here is the code.  And after that is the box I get with the
radio buttons but no shapes.

from tkinter import *  # Import tkinter

class Trafficlight:
    def __init__(self):
        window = Tk()    # Create a window
        window.title("Traffic Light")   # Set a title

        # Place canvas in the window

        self.canvas = Canvas(window, width = 480, height = 480, bg =
"white")
        self.canvas.pack()

        # Add three radio buttons to frame1
        frame1 = Frame(window)   # Create and add a frame to window
        frame1.pack()
        self.v1 = IntVar()
        self.v2 = IntVar()
        rbRed = Radiobutton(frame1, text = "Red", bg = "red",
                variable = self.v2,
                value = 1,
                command = self.processRadiobutton)
        rbYellow = Radiobutton(frame1, text = "Yellow", bg = "yellow",
                variable = self.v2, value = 2,
                command = self.processRadiobutton)
        rbGreen = Radiobutton(frame1, text = "Green", bg = "green",
                variable = self.v2, value = 3,
                command = self.processRadiobutton)

        rbRed.grid(row = 400, column = 1)
        rbYellow.grid(row = 400, column = 2)
        rbGreen.grid(row = 400, column = 3)

         
         
        window.mainloop()    # Create an event loop

    # Display a rectangle

    def displayRect(self):
        self.canvas.create_rectangle(10, 10, 100, 100, tages = "rect")

    # Display a Oval for the top light

    def displayOval(self):
        self.canvas.create_oval(10, 10, 10, 10)

    # Display an Oval for the middle light

    def displayOval(self):
        self.canvas.create_oval(20, 20, 20, 20)

    # Display an Oval for the bottom light

    def displayOval(self):
        self.canvas.create_oval(30, 30, 30, 30)



     
     
      

    # Add Radio Button process below once I figure that out

    def processRadiobutton(self): pass

Trafficlight()

from tkinter import *  # Import tkinter

Trafficlight()
