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

[Patrick M. <dus...@gm...>]

Hello,

I agree, and I'd like to take this opportunity to say, I think core Tk is
missing some features that might be considered basic today, which other
competing GUI toolkits probably have built in.

I'd suggest that having these features in the core might be a good idea:

- scrollable widget containers / scrollable frames

- drag and drop

I recently made a small utility that needed drag n drop. I had to load an
extension for that, and it complicated getting it to work across platforms.
I think I got it working on Linux and windows but not macOS.

Regards, PM

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.

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.
