In TCL, what are ".list" and ".desc" syntax used for? Where can I learn more about them?

I'm trying to understand some code written in TCL and convert it to Python. I skimmed through online docs for the TCL/TK language, and attempted some web searches, but I can't seem to find any documentation or description of what these syntax elements are: ".list" and ".desc"

Can anyone describe what this is called in TCL so that I can find references material about what it does?

Here's a small sample of the code. These appear to usually be found inside procedures. It seems like they setup or configure something.

proc makelist {args number } {
    .list delete 0 end
    .desc configure -state normal
    .desc delete 0 end

  • They appear to be widgets. In Tk, widget path names must begin with ..

    For example in your code, .list could be the path name of an entry widget (which supports the delete subcommand and which here would mean to delete everything that's in that entry's box). .desc could be the pathname of another entry widget.
