bulk88 says: Tk is old, and is a butchered dead end fork of TK from 15 years ago that separated Tk from the Tcl interp. Tkx is an marshalling bridge to a real Tcl/Tk engine. All bug fixes in Tcl/Tk interp automatically appear in Tkx. So do all new APIs.

boring and not relevant at all , and not a reason to learn Tkx

Even if everything you said about Tk is 100% true, and even if it were 100% important, Tk is still a milion times better than Tkx -- Tkx is the worst possible option

I've seen you remark on Tkx before, but I've not seen you write any Tkx code for people (or Tk for that matter)

Anyway, the OP is struggling with the basics, he won't be able to discover any of these bugs you speak of , that are irrelevant for most Tk users

I can't comment on Tkx as I never used it, but I must say to advise avoiding Tk just because it is older is wrong. I prefer the Stability of it. :-) It's nice not having your API change every 2 years as someone tries to add some whizbang features!! For many simple tasks, Tk is the way to go for it's ease of use and good documentation.... just like Perl5 itself.

:D Not exactly an example of treeview for the OP :)
