Description Julian 2022-07-28 18:46:43 UTC

I am using Okular on a surface-style tablet with a detachable keyboard. It works incredibly well, kudos to the team. Some behaviors I noticed that would make the experience even better, which might simply be flags to be set in the background.

1. Okular has a function to keep scrolling after clicking and dragging, when you leave off with momentum so to say (sorry I cannot describe it any better). This makes it so that when you lift your finger off the touch screen, sometimes the screen will go flying. I haven't really seen that in any other program, and generally it is a welcome feature, but it is a little bit to easy to set off with a touchscreen. You have to make a conscious effort to lift your finger right off, or the document will unintentionally go flying. Would be great to have an option to turn that off, or turn the sensitivity down.

2. The pinch gesture is used in wayland to go to the overview of open windows. That work with Okular, too, but unfortunately, it will unset your viewing settings, in particular "Fit Width". So it would be great if there was an option to lock "Fit Width" or any other zoom setting.

3. Wouldn't be surprised if there is nothing that can be done over this, but I seem to be unable to change textbox sizes when I add an Inline Note. I can only move the note around.

Overall, very good experience though! I bought the device just to use Okular, and it's great! I wish I could convey just over text how stoked I am. This is a love letter as much as it is a feature request.

Edit: version is 1.10.70, could not find that in the drop down menu.

You are right, most versions are apparently gone.
I notified the kde-devel mailing list.

> 1. [...] or the document will unintentionally go flying.

I think we fixed that in version 20.12. You use 1.10 (meaning 20.04), so you should try updating. 1.10 unfortunately has several issues with scrolling (which were introduced after 1.9).

That would probably require to turn off pinch gestures entirely?

There are no eight small squares in the outline of the box? These should be resize handles.

I am closing this bug report, since Bugzilla is meant to have only one issue per bug report.
Please open individual bug reports for each issue. :)

1. Glad to hear that scrolling is fixed.

2. Yes, turning off the pinch gesture is what I had in mind. One could imagine some more fine grained control options regarding when zoom gets actuated, but that might hardly be worth the effort. My main machine has a touch screen, too, and I can attest that zooming is never something I want to do when I touch the screen, it only ever happens on accident. Folks who look at more technical documents with detailed diagram probably appreciate the feature more than me though.

3. The eight squares are there. I did a little bit more of trial and error on my two machines, and I think I figured out what the problem is. They are just two small two hit with a finger, and even with a stylus it is very difficult to hit them--I vaguely remember having that issue with my mouse, too, when I first started using Okular. So the solution might be to make the clickable area a few pixels bigger than the squares. Even when I am very intentional, I can only hit the squares about 50% of the time on a touchscreen.

*To be more specific on the positives, if somebody from the team comes across this*: the configurable toolbar is just a *bomb* to use on a touchscreen. Killer feature!

Missed your last paragraph, I will open two bug reports for the two requests.
