Horizontal scroll support

[matthew-dean]

When using a trackpad on mac, horizontal swipes don't translate to horizontal scrolling, as they would if iScroll was not present.

An option to translate vertical scroll wheels to horizontal scroll (for horizontal-only iScroll panels) would be nice too.

Yes, this will be very usefull

[vbmedia]

Yes, this would be very helpful!

v4 or earlier is not supported anymore. Please check out v5 if you have this issue.

[matthew-dean]

Does that imply v5 supports this?

[davidpfahler]

What do you mean by horizontal swipes? The horizontal demo works find on my mac when clicking the trackpad and dragging one finger. Is that what you mean?

I believe that he refers to right/left flicks (without clicking/pressing the touchpad). It is a bit dodgy right now, if you perform a very fast flick it seems to be working, slightly slower ones do not respond.

This issue occurs on mac and other OSs with two finger scrolling. It also might occur when using a mouse with horizontal mouse wheel capabilities.

In addition, with scrollX: true and scrollY: false the vertical mouse wheel event causes iScroll to scroll horizontally. While this may be desired for some applications, this is not intuitive behavior and should not be the default for users without horizontal mouse wheel capabilities.

Not sure if two finger, no-click scrolling on touchpads should and can be supported. @cubiq ?

low pri- but I'll look into this

[bpeacock]

The source of jquery-mousewheel might provide some insight. The readme says that the plugin returns deltaX and deltaY that are normalized across platforms.

[bpeacock]

I pulled some of the jquery-mousewheel code and have a rough version of horizontal scrolling working in this fork. This also should fix #568 since it takes into account the event.deltaMode for scrolling which gives a unit distance for the scroll event. It's not perfect yet but should be a start to fixing these issues.

Any update on this issue? bump I'm trying to figure out why does the horizontal demo work with horizontal swipe, but using scrollX: true with scrollY: false doesn't

May be related with PR #523

[matthew-dean]

#523 looks to be an option to set whether or not if a vertical scroll will scroll a horizontal iScroll. This is about if a horizontal scroll will scroll a horizontal iScroll.

The math should be pretty much identical, just on a different axis. In fact, I have a patch to translate both horizontal and vertical scrolls to a horizontal scroll, but I haven't made a PR for it.

@matthew-dean did you ever make a PR with you changes? That would be really nice to spread the wisdom on that :)
