pack_forget does not erm remove either ;)
from Tkinter import *
root = Tk()
root.title("Pack is BEST!!!")
l = Label(root, text="Pack is simply the best")
l.pack()
def forget():
l.pack_forget()
def remember():
l.pack()
b = Button(root, text="Forget about it", command=forget)
b.pack()
b = Button(root, text="Wait, I still need you", command=remember)
b.pack()
root.mainloop()
BUT... the remember function packs the label widget in it's new packing
order, so it is packed after the two buttons, as far as I know the only
way to 'remember' its pack position is to put it inside a Frame widget
(and leave the Frame where it stands) - at least thats how I do it
To the OP I guess you've seen how easy this is with Tk(inter) :)
Cheers,
Martin.
