Dolphin: no CTRL+MWheelDown icon zoom out

Desktop Environments Plasma
1

Hello,

I have had for some time (I think it coincides with 5.27 but I’m not sure) a pb on my main machine whereby I can increase the size of icons in Dolphin with CTRL+MWheelUp, but cannot zoom out with the reverse operation CTRL+MWheelDown.

Needless to say, the problem is not mechanical; such actions work fine everywhere else.

Furthermore, I have two other machines (both laptops) with EOS, similarly up-to-date, which do not exhibit that behaviour.

So I assume that I have some conflict with some setting somewhere, somehow, but I have no idea where to look. Obviously Dolphin’s shortcut configurator lists only pure keyboard shortcuts, which this is not.

Any idea?

Nobody has any idea?

I have a vague feeling I’ve encountered this problem before, too.

Hello, I also suffered from this bug, I don’t have a definitive solution, but I temporarily solved the problem by doing this:

I added zoom in and zoom out icons to the doplhin taskbar.

After using them once, the CTRL+MWheelDown function started to work.

My distribution however is void linux with KDE plasma 5.27.10 and dolphin 23.08.3.

Hi and thank you very much for the input. (edit: and welcome to those boards!)

I’ll do you one better:

  • fresh session [edit: doesn’t have to be, it seems]
  • start dolphin: can zoom in, not out
  • switch virtual desktop (further testing: don’t have to switch desktop, just using “present windows” suffices, even if just to dismiss it – works 100% on like 7 consecutive tests)
  • switch back to desktop with dolphin
  • NOW I can zoom in

Also works on a second instance of dolphin, so the session does not have to be fresh.

I just noticed that while typing an answer to you :sweat_smile:

Does that work for you as well?

Hmm, switch virtual desktops don’t work for me :thinking:
but another discover, easier this time:

Just open dolphin and use the CTRL+ + and CTRL + - keys at least once and that’s enough, the zoom to increase and decrease the icons using the mouse scroll starts working, even on first run.

Thank you for your response after long months of inactive thread :+1:

Have you tried desktop effects such as “present windows”? I have them on screen edge. My testing showed that actually switching desktop or even windows was not necessary; it may not be sufficient either. I just noticed the effect while switching deskop, but probably only because that involved a desktop effect; the switching itself may be irrelevant.

Also, I’m on X11; Wayland may be different.

Tested, it works for me as well :+1:

That’s the magic of email notifications! :wink:

Thanks for reviving it!

It gets better: even switching focus to and from Dolphin’s built-in terminal, or to any other window, works…

… but only if you’ve already zoomed. Preemptively switching does not work.

So nothing to do with desktop switches or effects.
