If you really want to have a scrolled Frame widget in Tkinter you will have to use some "3rd party" widget; I never actually used it myself, but I think the ScrolledWindow widget that comes with the standard library's Tix module should be usable. There is also a ScrolledFrame widget that comes with Pmw (http://pmw.sf.net). There are also some "standalone" ScrolledFrame widgets available, that may or may not be Python3-compatible. For your particular case it looks like the good news is that you need none of these (at least if I understood correctly what you want to achieve), because you can simply make use of the Listboxes itemconfigure command, as in: mylist = Listbox(root, yscrollcommand = scrollbar.set ) i = 0 for c in COLORS: mylist.insert(END,c) mylist.itemconfigure(i, background=c) i += 1 If you are really ambitious you can even try to change each item's foreground, selectbackground and selectforeground colors appropriate to its background.
