Hi all, I've just started working with Python and Tkinter.
One of the things I think I've noted is that Button commands do not pass
parameters.
Is there a way around this?
And is there a better way to code the following:
I've written a small application that puts a Label in row 0 of a Frame and puts
26 buttons labeled A - Z in the second row.
When the user clicks on a button, the associated letter is displayed in the
label.
Code follows:
# Creates a label in row 0
# Creates 26 buttons A - Z in row 2
# Clicking a button changes the displayed label
from Tkinter import *
class Application(Frame):
def __init__(self,master=None):
Frame.__init__(self, master)
self.grid()
self.tv = StringVar()
self.tv.set("?")
self.lText = Label(master, textvariable = self.tv)
self.lText.grid(row = 0, columnspan = 26)
butA = Button(master, text= 'A', command = self.choseA).grid(row = 2,
column = 0 )
butB = Button(master, text= 'B', command = self.choseB).grid(row = 2,
column = 1 )
butC = Button(master, text= 'C', command = self.choseC).grid(row = 2,

butE = Button(master, text= 'E', command = self.choseE).grid(row = 2,
