Qt has Gesture support since a long time. This must be introduced in preview/canvas model view events. https://doc.qt.io/qt-5/gestures-overview.html I support this request! Pinch to zoom is sorely lacking in Digikam: it's so much faster when you have a trackpad... Please give it some thought :) I currently use trackpad for pan and buttons for zoom as a workaround when only using trackpad, but everything on the trackpad like when using the map would be better (https://www.reddit.com/r/digiKam/comments/1pqg6dy/trackpad_gestures_in_preview_mode/) Q : Which kind of computer + OS did you uses with a trackpad and gestures support ? (In reply to caulier.gilles from comment #4) > Q : Which kind of computer + OS did you uses with a trackpad and gestures > support ? Sorry Gilles, it's true that I forgot this very important information! For me, it's a MacBook / macOS 15 (until macOS 26 is in better shape...) ok i will prepare the code to support the gesture, but i don't have yet a linux machine with a trackpad. My macbook pro has all the stuff, but hacking is complicated and longer that with Linux. My UTM VM with Linux do now emulte the Macbook trackpad. I will use later my office Dell Linux laptop while Christmas time. So wait few days for a digiKam 8.9.0 test version. Gilles Caulier Amazing, thank you very much! Git commit 9efe5a78102d58d4aa017c55329703e35d29f02b by Gilles Caulier. Committed on 22/12/2025 at 09:16. Pushed by cgilles into branch 'master'. First support of gesture events in preview widget. Supported events are: - Pinch gesture event to zoom preview in/out centered on mouse position. - Pan gesture event to move zoomed preview contents. - Swipe gesture event to change current preview item (previous/next). Only the Pan gesture event can be tested under Linux, as gesture support is limited. macOS and Windows need more testing for all events supported.

The best OS to check all support will be macOS. The builds will be available while today at this place (after 1:00PM Paris time) : https://files.kde.org/digikam/ Thanks for your feedback Best regards Gilles Caulier Created attachment 187865 [details]
Plasma 5 from Kubuntu 24.04 LTS trackpad support.
The Linux KDE Plasma 5 from Kubuntu 24.04 has a limited support of trackpad/gesture support.
Here the test computer is a DELL Precision 7680 laptop : https://www.dell.com/en-us/shop/dell-laptops/precision-7680-workstation/spd/precision-16-7680-laptop/xctop7680usvp tested on my macbook pro : it works as expected. At first, I thought the swipe wasn't working, but then I realized I needed to use four fingers (maybe it would be a good idea to accept three fingers as well?). Otherwise, everything works great on my MacBook, thank you! Under macOS, by default 3 fingers is used to switch between applications. In Control Center, set 4 fingers to switch between Applications and 3 fingers ti change pages, et voila... Gilles Caulier |
