You will want to have a look at the Listbox widget's <<ListboxSelect>>'
virtual event, which is generated each time the selection changes (see
the listbox Tk man page for details). A brief usage example:

#########################################
from Tkinter import *
root = Tk()
l = Listbox(root, selectmode='multiple')
l.pack()

def on_select(event):
    print event.widget.curselection()

l.bind('<<ListboxSelect>>', on_select)

for i in range(10):
    l.insert('end', 'Item %d' % i)
root.mainloop()
#########################################

I hope this helps

Michael
