Okular 20.04 has introduced fantastic kinetic scrolling with acceleration momentum on mouse drag, touch drag and page up/down keys. But trackpad scrolling is missing the kinetic momentum. If I switch from dragging the page to using the normal scroll gesture on my trackpad, the missing momentum feels like there is something wrong. Also see 413989
I would like this too.
Do you think we shouldn’t use QScroller::scrollTo(QPoint, time=0) for such continuous scrolling events, but QScroller::handleInput()? Pro: The Browse tool already uses handleInput(), and that appears to work well. Contra: We need to fake the Grabbed and Dragging state, which could maybe(?) cause further bugs because we forget to update other scrolling methods. We also need to create a Release event, which is difficult, because when scrolling events stop, there are simply no further scroll events, while the Browse tool receives a mouse release event.

This feature is really important. It's a shame that Okular does not support it yet :/

(In reply to Nate Graham from comment #1) > I would like this too. I just filed a wishlist item for this feature in Dolphin. Similarly, there is a version of kinetic scrolling when using a mouse wheel, but using a touchpad is kludgy.
It would also be cool to be able to do pinch to zoom on documents.
Kinetic scrolling and pinch to zoom would be awesome features for Okular under Wayland
