[Tutor] using a button to make a variable in Tk

[Kent Johnson]

Patrick,

It sounds like you need to add command handlers to the buttons. The 
handlers could set the variable, but a simpler approach is to have 
functions that just do what you want - the handler for the exit button 
exits the program; the handler for the update button starts the update. 
Here is an example. When the 'Stop' button is pressed the program will 
exit; when the 'Update' button is pressed, App.updateParcels() will be 
called:

from Tkinter import *

class App:

   def __init__(self, master):
     frame = Frame(master)
     frame.pack()

     self.button = Button(frame, text="continue on and update parcels", 
fg="red", command=self.updateParcels)
     self.button.pack(side=LEFT)

     self.stop = Button(frame, text="Stop the update process", 
fg="orange", command=frame.quit)
     self.stop.pack(side=RIGHT)

   def updateParcels(self):
     print 'Time to update the parcels'

root = Tk()
app = App(root)
root.mainloop()
