I've searched my externals and online and have tried hcs and hid and neither work. (hcs does not see the mousewheel from inside the gemwindow and hid sends constant (at poll rate) output (so is never completely off). (note: due to my OS I am using Pd version: Pd 0.50.2).

Simply, I want to be able to "zoom" like one would on the z-axis of an online map. So on each mousewheel click up or down it increments or decrements a value.

Thanks, in adavnce. I look forward to your suggestion, advise, link to external, abs, or just image/sketch of how to do it.

Peace through sharing.

@svanya I think you will have to "click and drag".
Say left-click or middle-click from [gemmouse] to open a spigot that lets y-axis data from [gemmouse] through to control your z-axis.
You will need to zero and then scale the data, or maybe normalizing the data..... [gemmouse 0 2] for example... would be sufficient.

@whale-av
Thank you for the input. I really appreciate it.

I think I got it worked out. See below.

Found out gemmouse does send a mousewheel event, but only as if it were a bang to the XY.

So if you keep the mouse still, ie trap for not changing, you can safely assume (if you also trap for click changes) that the result out is the mousewheel event.
