Lines in Tkinter

Back to index
This is the first assignment in which Tkinter is used. Whereas the turtle graphics module is not all that popular, the Tkinter package is the most used GUI (Graphical User Interface) when it comes to Python. Get the following sample program up and running.
#!/usr/bin/python from tkinter import * tk = Tk() canvas = Canvas(tk,width=300, height=300, background="black") canvas.pack() canvas.create_line(0,0,150,150,fill="cyan", width=3) canvas.create_line(300,0,150,150,fill="yellow", width=3) canvas.create_line(300,300,150,150,fill="pink", width=3) canvas.create_line(0,300,150,150,fill="magenta", width=3) for x in range(160,300,10): canvas.create_line(150-(x-150),x,x,x,fill="white") canvas.create_text(145,15,text="N", fill="red") mainloop()
Certain lines in this sample program will appear in one form or another in any Python program utilizing Tkinter. Obviously all or part of Tkinter must be imported, but less obviously four key lines must appear:
master = Tk() w = Canvas(master, width=400, height=300) w.pack() ... mainloop()
The rest of the program utilizes constructs already introduced in previous lessons or is otherwise fairly self-explanatory. You should experiment with create_line to make sure you understand how it works. Actually, mainloop() is optional in static programs such as the demo program shown above.
ASSIGNMENT:

Make the following changes to the sample program:

  1. Using the method demonstrated in the sample program, place vertical lines in the left and right quadrants
  2. Place horizontal lines in the top quadrant to match those in the bottom quadrant.
  3. Place W, E, and S as appropriate to match the N in the sample program
