Hi,
I guess there's something basic I need to know.
Given the code below if I press the button and
p and q is highlighted then close the window
I get:
Output:
>>> dddd
[]
('15', '16')
dddd
[]
But the x does not seem to persist outside of the
def selected() block. I want the final last button
press to persist so I can use those indexes for
further processing. What am I missing here?
Thanks.
import sys, string, Tkinter
from Tkinter import *
root=Tkinter.Tk()
frame=Tkinter.Frame(root)
listbox=Listbox(frame, height=27,selectmode=MULTIPLE,
font=('courier', 12))
listbox.pack(side=LEFT,fill=BOTH, expand=1)
choices=map(chr, range(97, 123))
for item in choices:
listbox.insert(END, item)
frame.pack(fill=BOTH, expand=1)
def selected():
x = listbox.curselection()
print x
zz='dddd'
btn = Button(root, text = "Click for values",
command = selected)
btn.pack()
#test
print zz
print x
root.mainloop()
#test
print zz
print x
