Hi Alex, Are you talking about this:
http://who-t.blogspot.ca/2011/12/multitouch-in-x-getting-events.html If so then what you need to do is implement the X Input 2.2 extension in CLX. It might not actually be all that hard. Hell, maybe someone has already done it? The X protocol is just bits and bytes sent over a socket. So anything can implement the protocol and be an X client. That's what CLX does. It implements the protocol from the ground up in Lisp. For better or worse that means you can't just piggyback off all the work done in C and write a little FFI code to get access to the functionality. Anyway, if you have the time and energy it might be a lot of fun to implement XInput in CLX. You'd probably get a warm round of applause from the lisp community. -Shawn On Fri, Dec 6, 2013 at 3:21 PM, Alexander Popolitov <popo...@gmail.com> wrote: > > On 12/06/2013 10:12 PM, J.
