G'day penmkr,

You asked an almost identical question just over a fortnight ago: "creating a listbox in tkx". That also confused Tk with Tkx; contained an incorrectly copied method name for creating listboxes; complained about the tutorials; and presented URLs, not as links, but as plain text.

I spent a fair amount of time responding to all of these issues; as well as providing a large amount of additional information (including a lot of links to related documentation): "Re: creating a listbox in tkx".

Go back and read it (again). The answers haven't changed.
