…ents. - Click and adjustment state is now tracked for each pointer ID individually, rather than globally. - If a user selects the slider knob, the adjustment will be proportional to the knob movement. This allows for finer adjustments. If the user clicks elsewhere on the slider, the adjustment is based on the absolute position of the click.

It reacts a little weirdly. Using "./mame obdmx -now -screen screen1
-enable_touch" (screen1 is the one in my three screens that has touch),
multitouch works. For instance I can move two sliders independently at the
same time. But the mame mouse appears, moves kinda randomly, and considers
there is a click when touching the screen somewhere else. For instance
with the dmx, if the mouse happens to be over one of the pads and you touch
another, both pads will be triggered. It's kinda weird.
I've not been able to understand how the mouse moved. Without
-enable_touch, it moves following relative movement when touching the
screen (e.g. no absolute positioning). With it... it's just weird.

This is a followup to the discussion in #13177
<#13177>. Tested on a single-mouse
setup.
This should also work with multiple pointer devices, and touchscreens
(assuming the latter generate "button press" events). But I was not able to
verify. I tried testing with multiple mouse cursors (using xinput and
multiple mice), but it seems like SDL2 does not support that. I also tried
emulating a touchscreen with evdev, but this didn't work either. If
someone has a way to test multiple cursors or emulate a touchscreen on
linux, let me know. Alternatively, if someone with a touchscreen can
validate, that would be great!

Thanks for taking a look! To rule out the script itself as the source |

Yeah, the issue is elsewhere. And I solved the weirdness: the mame mouse moves by exactly how much you moved the finger while touching, but in one step once you release the touch. Still needs to be solved before (multi?) touched is fully usable. It's very nice to have a real driver to try with. |
