Unify behaviour of mouse-wheel and mouse-drag image scrolling

[DD-P]

Hi.
I've re-done this PR from scratch, noting the comments in #347. Please let me know if the behaviour is now working appropriately for you.

Hi, David,

We couldn't have a 2nd look at your nice work yet. We are very thankful for your collaboration and we'll be reviewing soon, ok?

Best!

Thanks Tiago. Yes, that's no problem. I could see that the 3.0-3.1.x series was being fine-tuned for release and expected this to be looked at later. You will want to be confident that changing the UX with this PR is correct, so not something to be rushed!

Tested and reviewed again. Working!

About not reversing scroll direction when Mac OS preferences for mouse scroll is set to Natural, I agree that it should reflect in Horos Preferences, disabling the reverse scroll option. I will open an issue, but it is no big deal...

Thanks again. As commented in other topic, the subject of informing credits of the changes in Horos is on the way...

Best,

Tiago

Hi all
I was trying to find a solution online for exactly the same issue of HOROS and hit on this forum. Thank you for bringing in this issue. Unfortunately it does not appear to be fixed.
What I did according to solution given above ...

1. Set mouse scroll direction to Natural by checking the box in System Preferences MacOs
2. Unchecked Reverse Scroll in Viewers Preferences in HOROS
   Tried the same example of scrolling though chest CT
   Mouse wheel working correctly , rolling towards us shows images that are inferior
   Mouse Drag not working correctly , if you drag it towards you the images go to upper sections of the chest rather than intended lower.
   This has caused annoyance to many of my students for whom I introduced HOROS for training.
   Would be very grateful if this issue is opened again to fix it.
   Many thanks in advance.

Re-opening. Please consider for the 4.0 series now under development.

Many thanks for opening it. Happy to see that it is opened again for a solution. I tried all advice given earlier in our forum and as they did not work, got a third party free application for Mac to fix it. Have been using this ever since. However I would be delighted to see a solution in our forum here.

Hello. Is it possible to change mouse drag direction as an option in future? Coming from GE software is really confusing
