[Tutor] Tkinter frame background colour

[alan.gauld at yahoo.co.uk]

   You are building a grid so why use the pack manager? it would all be so
   much easier if you use the grid manager.
   For the red lines I'd consider setting the borders of the entry widgets as
   a possibility. But I haven't tried it....

     My original GUI worked but it was a bit of a mess so I've spent most of
     the day building a new interface to my sudoku solver. However, there is
     one problem. I used to have a red line after the third and sixth column
     of boxes, the same with the rows. I achieved this by setting the frame's
     background to red and placing some padding after the third and sixth
     group of cells so that the red background would show through and show a
     red line between the 3 x 3 boxes. Otherwise, I'm happy with the result.

     import tkinter as tk

     class Root(tk.Tk):
         def __init__(self):
             super().__init__()

             self.title('Sudoku Solver')
             self.geometry('300x300')

             self.frame = tk.Frame()
             self.frame.pack(expand=True)
             self.frame.bg="red"

             self.entry = [None] * 81
             for i in range(81):
                 r, c = divmod(i, 9)
                 self.entry[i] = tk.Entry(self.frame, width=2,
     justify=tk.CENTER, fg="red")
                 #if i == i % 3:
                 pad_x = (4, 0)
                 self.entry[i].grid(row=r, column=c, padx=pad_x)

             self.control_frame = tk.Frame()
             self.control_frame.pack(side=tk.TOP, pady=5)
             self.b_quit = tk.Button(self.control_frame, text='Quit',
                 command=self.quit)
             self.b_quit.pack(side=tk.LEFT)

             self.b_solve = tk.Button(self.control_frame, text='Solve',
                 command=self.solve)
             self.b_solve.pack(side=tk.RIGHT)

         def quit(self):
             self.destroy()

         def solve(self):
             self.entry[2].insert(0, '9')
             print(self.entry[2].get())

     if __name__ == '__main__':

         root.mainloop()
