Disable h-scroll during v-scroll and vice versa

[cytopia]

Is it possible to disable horizontal scrolling while you scroll vertically and vice versa?
This seems to be the standard behavior on OSX with two-finger scroll and is kind of easier.

It happens a lot to me, if I am using half a browser width and pages have a big horizontal scroll, that once I scroll up/down I also move left/right by accident.

Any thoughts on this?

Are you sure you using current master?
It was fixed in #17

[cytopia]

I definitely have the above mentioned commit (when I check via git log) in your repo I compiled from source .

Anything else I can check? Any debug option I can turn on?

[p2rkw]

In this case I will have to first reproduce and then debug it. Please post your configuration (as described in readme)

I still have this issue, was this resolved?

Output of xinput --list-props 12 (bcm5974):

My configuration (not minimal) 10-mtrack.conf:

I'm on the latest commit (eb3b9c3...).

Is h-scroll triggered only at the bottom of the scrolled window? Which button events are generated (xinput --test )?

[rmanne]

No, when v-scrolling, h-scroll triggers whereever, even in the center of a webbrowser page . When scrolling up for example, it's some button press/release 5 intersperced with some button press/release 6. Partial output here: log.txt

Could you please also attach output of xinput list --long 12. I'm still struggling with reproduction.
Does this horizontal movement have same speed(distance) as vertical, or is it rather occasionally?

[rmanne]

To be completely honest, I thought it was initially it was the "default" effect. It's usually smooth and perfectly consistent. It jitters a lot when I move two fingers in a circle, but if it's just slight movements, mostly vertical, it's perfectly smooth. I made a gif to show the interaction:

Here's the output of xinput list --long 12:
log.txt

So, this is how SmoothScroll(aka. pixel perfect scroll) works: what we observe is just "inaccurate" v-scroll.
Looks like I will have to add another configuration variable to ignore "perpendicular" movement while other is active.

Please check how it behave with this commit: fe08710 before I push it to master.

[rmanne]

Solid, it works.

Slightly modified fix landed on master.
