[TCLCORE] Any plans on a tk scrollable frame and toplevel in the core?

[EricT <tw...@gm...>]

With 9.0 out the door, I was thinking that this might be a good time
to consider some of the "missing" pieces in the tk and ttk widget set.

I think the most useful missing piece would be a built in scrollable
frame and/or toplevel. If there's a TIP that has already requested
this, then feel free to ignore this email. And if perchance, it's
already there, then perhaps it just would need to be more prominent in
the documentation. At least, I couldn't find one.

When I needed a scrollable frame, I found there are many versions on
the wiki, but sometimes having too many choices makes the task harder.
There once were also several notebook widgets, and the one I chose, in
bwidgets, ended up not being the best choice. Had I known about
ttk::notebook, I would certainly have looked at that first.

Anyway, I think the one at
https://wiki.tcl-lang.org/page/A+scrolled+frame by Paul Walton is a
quite good one, although I didn't quite understand why I needed two
frames in the example.

There's also apparently a modified version just below it as well. And
that's the one I tried because it also had 2 smallish examples.

Paul's version is nice in that you can pack the scrollable frame, but
the scrollable items can be packed, grid'd or placed. I suspect you
could grid the frame as well, but I wanted to pack it.

Bottom line, I believe having this widget in the Tk core would be
quite useful, and it might even just be added there in script form.
But having one supported version that was in the "manual" would be
great and would also provide leverage for all the other languages that
use the Tk toolkit.

thanks
