touchDragging on IE11/Windows 8

[mrfind]

Hi darsain, thanks for an excellent and very useful library!

I ran into a problem using IE11 on a Windows 8 touch device (Fujitsu tablet): Everything seems to work fine except for touch dragging. I tried the demos on your page on Android and iOS phones: no problem. But in Win 8/IE 11 (both the "normal" and the "metro" versions) they show no reaction when I try to drag.

Any way to fix this?

[darsain]

Hm... no clue. I don't have any Win touch device to test it on.

Hi, we encountered the same problem here, works perfectly on windows 7/8, with IE11 as long as we use the mouse, but the touch won't do anything on a windows 8 tablet

Thanks for the work you did on the lib by the way ;)

So according to #178 it seems the dragging is being terminated because X&Y dragging paths are equal. I don't know why is this even happening. Usually (mouse/touch)move events are triggered for every pixel moved. This means that moving from A1 to B2 in here:

    1   2
   --- ---
A |   |   |
   --- ---
B |   |   |
   --- ---

Would trigger 2 events, as your movement is:

A1 -> (A2 || B1) -> B2

IE is probably merging multiple events into one. Or maybe something else is happening. Can't tell. I'd need an IE touch device :/

1.4.0, and consecutive 1.4.1 have a lot of fixes and some dragging related changes. Could someone try if some of these changes didn't fix this issue?

Testing in 1.4.4 the issue is still apparent. I have just tested it on a ASUS Vivobook in both chrome and IE, in chrome the touch gestures work, but in IE they don't.

I believe IE is hijacking the touch gestures as I know that on phones and tablets the left and right swipes are used for going back and forward in history.

This link might help but I wasn't able to make it work: http://stackoverflow.com/questions/13654238/can-i-disable-ie10-history-swipe-gesture

Wait, so it works for vertical Sly? Just not horizontal? And have you tried all suggestions in that question?

[maweeks]

I've tried the suggestions that I've found, and none have helped. The site I'm creating (only uses horizontal slys) and all of the examples on darsa.in/sly are not usable with the touch screen I am using. I'm on IE11.0.9600.17690 And yeah, I've tried all the suggestions that I can see here. Up and down drags always just scroll the whole page not the front element. Hope this helps

Experiencing the same issue using Microsoft Edge 20.10420.16384.0 on Windows 10.

Could it happen because IE does not support touch events (http://caniuse.com/#search=touch), but instead supports pointer events (http://caniuse.com/#search=pointer)?
