Possible mouse wheel bug?

[drivermix]

Hello,

I believe there's a bug when using the mouse wheel in this fashion. The results are completely erratic and unusable.

Alt{WheelUp WheelUp WheelUp} >> 3
Alt{WheelUp WheelUp} >> 2
Alt{WheelUp} >> 1

Same thing with the WheelDown option.

Obviously, the goal is to get 1, 2 or 3 depending on how many mouse wheel clicks are fired sequentially while Alt stays pressed. If I remove the first two lines and only leave Alt{WheelUp} >> 1, I get 1 consistently.

Incidentally, similar setups that do not use the mouse wheel produce correct results.

Here's one using keys only.

Alt{Space Space Space} >> 3
Alt{Space Space} >> 2
Alt{Space} >> 1

And here's one using a mouse button.

Alt{ButtonLeft ButtonLeft ButtonLeft} >> 3
Alt{ButtonLeft ButtonLeft} >> 2
Alt{ButtonLeft} >> 1

I've got no access to my computer at the moment to test, but I'm a bit surprised if the behaviour is as you described. This would imply there's an implicit timeout for consecutive key presses that applies to other mappings but not for the ones for mouse wheel. it t sounds like a bug to me also, but how long is the timeout?

When ever I've used similar mappings, I've defined the timeouts manually as in these macros https://github.com/ristomatti/keymapper-config/blob/main/include/key_sequences.conf

I could reproduce it and would also call it a bug. I created issue #280. Thanks for reporting!

No, there is no timeout. I only tested it on Linux so far. It works correctly once but after releasing Alt and pressing it again, it immediately keeps outputting Alt (instead of waiting for a WheelUp). It seems like some internal state is not reset.

Just to be sure, I was referring to this case:

Alt{Space Space Space} >> 3
Alt{Space Space} >> 2
Alt{Space} >> 1

With this configuration one has to release Alt after scrolling once or twice to get 1 or 2. But it can be released any time to trigger, there is no implicit timeout. Yeah, one could manually add a timeout when desired.

This should be fixed with 4.12.3.
