I am developing Static IP configuration GUI on ubuntu Linux using Python tkinter.As shown in this IP Configuration GUI figure Where I have two Label and two entry field and two button on root window.And I have a touch keypad on toplevel window.

I have to do following two tasks so could anyone help me out in below listed features:

1. Whenever I will click on particular entry field I have to pop up this touch keypad which I developed and have to insert a text on that entry field using that touch keypad.Right now both touch keypad and entry field window appeared together.
   
2. I also have to make entry field as shown in below figure. After 3 digits there should be a dot on entry field as like in IP address.
   

from tkinter import *

class Numpad(Frame):
    def __init__(self,root,rownum,colnum):
         Frame.__init__(self,root)
         self.grid(row=int(rownum), column=int(colnum))

    def numpad_create(self):

        btn_list = ['7','8','9','4','5','6','1','2','3','0']
        r = 0
        c = 0
        for b in btn_list:
                self.b = Button(self, text=b, width=3 ,height=3, bg='blue', fg="#FFFFFF", font=('bold',16),
                        activebackground='red', activeforeground="#FFFFFF", command = lambda btn=b:self.digit_action(btn))
                self.b.grid(row=r,column=c)
                c += 1
                if c > 2:
                    c = 0
                    r += 1
