Clientside: How to evaluate MouseWheelEvent according up/down, left/right


on clientside I added a
which fires
s. Everything works fine when I turn the mousewheel up and down. For example if I turn it up I get something like this:

delta y: -3, is norh: true, is south: false

But often there is also the possibility to press the mousewheel left or right in the meaning to scroll left and right. But when I press the mousewheel to the left, I get the same
as I turn it up:

delta y: -3, is norh: true, is south: false

I tried it with Chrome under Linux and Windows. Is there any possibilty to determine the direction of the mousewheel: left, right, up and down and not only left/up and right/down?

Thanks in advance, Philipp
