Indeed, the feature hasn't been implemented yet.

Interesting. I wouldn't have guessed something like this could be missing in 2023. Is there a way to mark this as feature request then?

I changed it to "wishlist" already to reflect that.

Vote for this feature request. Zooming with touchpad is indispensable for laptop. I think this should be a high priority on the wishlist. Please at least implement this in Wayland.

I would also like this feature.

IIRC Gwenview already has it, would it be possible to reuse any code from there?

This is the only reason I'm still using evince as my pdf viewer.

Adding to this.

My work in Windows 11 is more productive partly due to the "pinch zoom" on touch-pad, which is utilized a lot professionally when quickly zooming in/out in presentations and other various documentations. 

However, "pinch-zoom" works flawlessly on both my laptops touch-screens, in Okular, with KDE 6.1! So the feature is already there and working for touch screen displays, but for some reason missing for touch pads.

A possibly relevant merge request was started @ https://invent.kde.org/graphics/okular/-/merge_requests/1052

*** Bug 479821 has been marked as a duplicate of this bug. ***

I need this functionality to create a more natural workflow in Okular, especially since I use a trackpad on both my laptop and desktop.
Currently, I use a simple workaround: dragging with a middle-click in Okular.
To do this, I click on the document with three fingers and, while maintaining the pressure, drag forward or backward to zoom in or out.
While it works, it's neither intuitive nor practical compared to a standard two-finger pinch gesture, which is more accurate and less error-prone.
Without this workaround, I would probably switch to Evince, as others have suggested.

Any update on this? The MR in relation to this seems to have gone stale :T, pinch to zoom works on most other KDE apps, so Okular of all things not having it on touchpads is a really odd omission. (+ it makes Okular not as accessible as could be, unless you wanna use the desktop wide zoom feature, which would make the pdf in question blurry)

Operating System: Fedora Linux 42
KDE Plasma Version: 6.4.2
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1
Kernel Version: 6.15.5-200.fc42.x86_64 (64-bit)
Graphics Platform: Wayland

Bumping this so that the devs know that this is indeed a critical feature missing from a laptop point of view. I'm using Papers as of now on plasma but would want to use native kde apps for basic pdf stuff.

Creator of the MR here! I just updated it to the latest version and it seems to work. I marked it as ready to review, so hopefully it will get picked up.

Add native pinch gesture support in PageView

This is necessary to support not just touch gestures but also touchpad gestures.
Apparently QGesture is not implemented for Wayland, but QNativeGesture is...

You're the absolute best!!! Thank you so much for implementing this :) <3
