I am adding boxes to my program and am looking for
informatioin to get my box to activate diffrent parts
of my program. Anyone have a toutorial on this?
Example:
(BOX)
# File: toolbar1.py
from Tkinter import *
root = Tk()
def Deposite():
print "Amount:"
# create a toolbar
toolbar = Frame(root)
b = Button(toolbar, text="Deposite", width=10,
command=Deposite)
b.pack(side=LEFT, padx=2, pady=2)
b = Button(toolbar, text="Withdraw", width=10,
command=Deposite)
b.pack(side=LEFT, padx=2, pady=2)
toolbar.pack(side=TOP, fill=X)
mainloop()
(Action)
# I added the exception line so that negartive
numbers woudl not be added.
if choice == 1:
amount = raw_input ('Amount: ')
elif amount < 0:
raise ValueError, 'Deposites must be positive'
elif self.balance - amount < 0:
raise ValueError, 'The account only holds $' +
str(self.balance)
self._perform_transaction(-amount)
date = raw_input ('Date: ')
numbers[amount] = date
