[Tkinter-discuss] Make GUI

[Bob Greschke]

#! /bin/env python2.3

from Tkinter import *
from sys import exit

Root = Tk()

InputVar = StringVar()
OutputVar = StringVar()


######################
# BEGIN: class Command
# Pass arguments to functions from button presses and menu  
selections! Nice!
# In your declaration:  ...command = Command(func, args,...)
# Also use in bind() statements
#   x.bind("<****>", Command(func, args...))
class Command:
     def __init__(self, func, *args, **kw):
         self.func = func
         self.args = args
         self.kw = kw
     def __call__(self, *args, **kw):
         args = self.args+args
         kw.update(self.kw)
         apply(self.func, args, kw)
# END: class Command




###############################
# BEGIN: XSqCalc(InVar, OutVar)
def XSqCalc(InVar, OutVar):
     Value = InVar.get().strip()
     if Value == "":
         OutVar.set("error")
         return
     Value = float(Value)
     Value = Value*Value
     OutVar.set(str(Value))
     return
# END: def XSqCalc




Label(Root, text = "Enter a value in the field\non the left, click the 
\n\"X^2\"
button and see the\nanswer in the field on the right.").pack(side = TOP)
Sub = Frame(Root)
Entry(Sub, width = 10, textvariable = InputVar, bg = "white", \
         fg = "black").pack(side = LEFT)
Label(Sub, text = " ").pack(side = LEFT)
Button(Sub, text = "X^2", command = Command(XSqCalc, InputVar, \
         OutputVar)).pack(side = LEFT)
Label(Sub, text = " ").pack(side = LEFT)
Entry(Sub, width = 10, textvariable = OutputVar, bg = "white", \
         fg = "black").pack(side = LEFT)
Sub.pack(side = TOP, padx = 5, pady = 5)
Button(Root, text = "Quit", command = exit).pack(side = TOP)

Root.mainloop()


That python2.3 line at the beginning may need to be changed for your  
system.
The text of that first Label() should all be on the same line.
