Multi-touch support

[lipigl]

Hi!

I am planning to run the NoMachine client on a Tablet running Windows 10, and the server on an Jetson TX2 running Ubuntu 16.04. I would like the applications running on the server to be able to respond to multi-touch commands (not necessarily two-finger-scrolling, pinch-to-zoom and so on, but basically being able to command two on-screen sliders at the same time). Is NoMachine able to send multiple touch events to a Linux /dev/input/eventN device?

Thanks!

Not at the moment, but we can check how the client receives those events and how to use them on the remote OS in order to see whether adding support for it is possible. It’s certainly not a trivial thing 😉

Hi Britgirl,

Thanks for the answer! Well, even if the touch events are not sent in a standard way (i.e. /dev/input/eventN), I could (if the protocol were accessible and documented) handle the non-standard way within my application. Is there any information on that topic?

It’s not a question of missing documentation about multi-touch events, it’s that multi-touch events are not handled at all. As I wrote earlier, we first need to first evaluate how such events are received to be able to send them to the server in order to add support for multi-touch commands. Definitely something to explore further.

Oh I see… Sorry for the misunderstanding!

Well then, I guess we will have to handle our commands through a separate application in the meantime.

Thanks for your time!

A small clarification to what Britgirl wrote – obviously we handle multi-touch events such as the ‘traditional’ two-finger swipe or pinch-to-zoom in our iOS and Android apps, and we will add support for them on Windows tablets soon.
