[Tkinter-discuss] Binding a List to a ScrollBar

[Nicco Kunzmann]

Hello Rob,

as far as I remember you can only insert text into a Listbox.
Maybe you pack Widgets onto a Listbox they appear but it does not make
them items.
Try this:
    mylist.insert(END,*c* )
    mylist.itemconfigure(END, background = c)
If you want to change the background.

Greetings,
Nicco
