Iain,
I made a small test program (Fairly new in Tkinter), i have not found the
solution but i came across something, maybe somebody can throw more light on
this ?
Test Code (Active Python IDE 2.6 , Windows XP, Tkinter 8.4)
import sys
import pdb
from Tkinter import *
headers='ll'
machines= 'zt'
lbl = [[0]*len(headers)]*len(machines)
flag=0
root = Tk()
for i in range(len(machines)):
for j in range(len(headers)):
lbl[i][j] = Label(root, text= str(i)+str(j), bg = 'red')
lbl[i][j].grid(row=i, column=j, padx=10, pady =5)
*print lbl # something that was noticed*
#print lbl[0][1]
lbl[0][0].config(text= 'row=0, column=0') # changes the text in lbl [1] [0]
lbl[0][1].config(text= 'row=0, column=1') # changes the text in lbl [1] [0]
lbl[1][0].config(text= 'row=1, column=0')# overwrites the text in lbl [1]
[0]
lbl[1][1].config(text= 'row=1, column=1') # overwrites the text in lbl [1]
[0]
root.mainloop()
*OUTPUT*
>>> [[<Tkinter.Label instance at 0x012B3B70>, <Tkinter.Label instance at
0x012B3AA8>], [<Tkinter.Label instance at 0x012B3B70>, <Tkinter.Label
instance at 0x012B3AA8>]]
The instances generated in row wise are the same, but within a row they are
different...
something more can be learnt from that?? hmm, i got to leave now.
Thanks
Madhu
