Addition Application

So following on from the previous posts, I am how sharing a small application, that makes use of what we have been learning.

This presents 2 input boxes and an output box, any values entered in to the first two, the sum is placed in to the last box.

This is not perfect, but getting there slowly.

We need to:-

The code for the above is as follows.

#!/usr/bin/env python
import Tkinter # note use of caps
from Tkinter import *

window = Tk()
window.title('App 1')
window.geometry("650x125") # w x h
window.resizable(0,0)

#define button actions
def btn1():
	#convert box text in to integers	
	ent1 = int(entrytext.get())
	ent2 = int(entrytext2.get())
	
	#add the 2 integers and store in variable add
	add = (ent1 + ent2)
	print add
	
	#instert value add in	to box outtext 
	outtext1.insert(0,str(add)) # insert response
	
btn_tog2 = Button( window, text ='button1', command=btn1)
btn_exit = Button( window, text ='exit',command=exit)	

# define some labels
box1 = Label(window, text="Entry 1: ")
box2 = Label(window, text="Entry 2: ")
box3 = Label(window, text="Ouput1: ")

#define entry box 
entry1 = StringVar() # this is our entry box
entry2 = StringVar()
entrytext = Entry(window, textvariable=entry1) # this is our entry box
entrytext2 = Entry(window, textvariable=entry2) # this is our second entry box

#define out box 

entry2 = StringVar() # this is our output box
outtext1 = Entry(window, textvariable=entry2) # this is our output box

#display boxes
entrytext.grid(row = 3, column = 2,)  #display entry box
entrytext2.grid(row = 3, column = 3,)  #display entry box
outtext1.grid(row = 3, column = 4,) #display output box

#place labels
box1.grid(row = 1	, column = 2, padx = 5, pady = 5)
box2.grid(row = 1	, column = 3, padx = 5, pady = 5)
box3.grid(row = 1	, column = 4, padx = 5, pady = 5)

#buttons
btn_tog2.grid(row = 3, column = 5, padx = 5, pady = 5)
btn_exit.grid(row = 3, column = 6, padx = 5, pady = 5)

window.mainloop()
