I'd like to equip my widgets with smooth scrolling.
I mean smooth scrolling with inertial scrolling, and with bounce at the
top/bottom of the page.
Something like scrolling a page in a browser. Scrolling should be based
on <MouseWheel> (or two finger drag on a trackpad).
Can you help me or give me some examples?

Thank you.

The scrolling utils package may be helpful: https://www.nemethi.de/

I really admire all Csaba's works; I tested the last scrollutil version
(2.2) again.
In particular, demos/pagesmandemo.tcl is really close to my
expectations, but it's not really what I'm looking for; ok for inertial
scrolling, but there is no bounce effect when exceeding the lower/upper
limit of a page.

So, you have half of your desired request in that package. That means
you now only need to build the missing half instead of all of it. And
perhaps Csaba would take a code donation to add the 'bounce effect'?

As I know magic Csaba, it would be great to describe in detail what you
want and it might just happen ;-).

Take care,
Harald
