Scroll on trackpad/touchpad doesn't trigger mouse wheel options

Anonymous 4 years ago updated 2 weeks ago 7

I love the ability to change volume by scrolling on the mouse wheel. However, it doesn't seem to work when I scroll on my trackpad.

I'm also getting this problem. Works fine with a normal mouse but can't change the volume with the trackpad. 

I also have this problem. Would like to see it fixed soon.

Unfortunately, I don't know how to make it work. I can reproduce the problem, but what happens is that the taskbar doesn't receive any mouse wheel events at all. You can see it with the Microsoft Spy++ tool. The corresponding message is WM_MOUSEWHEEL.

I have the same issue, however I accidentally found out that doing the "pinch to zoom" gesture works. From Spy++ output, it seems that doing that basically sends Ctrl+scroll events (MK_CONTROL and WM_MOUSEWHEEL).

Yep "pinch to zoom" event over taskbar works to change volume for me too.

Maybe it could be workaround somehow to send these "pinch to zoom" events by touchbar scroll..?

 

Maybe with your trackpad software, but I don't see how I can do it from the tweaker as it doesn't get any indication about touchbar scroll events.

Awesome - confirmed "pinch to zoom". I'm on a MacBook Pro with Boot Camp and its recent updates to enable Windows Precision Touchpad support in Windows 10.
