Indeed, multi events seem to already provide the needed "pen data". Do you need any data that is not already provided from the multi events? Can you be more specific? I know that some data, although there are attributes available from the events structure, might have not been implemented, like pressure, angle and radius. But the infra is there. > Is there any interest in providing EFL applications with pen data? > More importantly, is there anyone willing to help a newbie to the > project like myself? If you are providing something new, I think it's a good idea. But would be nice to look carefully if we don't provide the means to work with the said pen data already. Send your proposals to the list and people will give it thoughts. BTW, take a look at the multi-touch example, it might be helpful and you could improve it if you want: https://git.enlightenment.org/core/efl.git/tree/src/examples/evas/evas-multi-touch.c Regards, Rafael ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
