I noticed that when I start the server, the server calls both seat_get_pointer and seat_get_keyboard. In seat_get_pointer and seat_get_keyboard, the resource_list is populated for these two devices, but the server does not call the seat_get_touch. I was wondering why does the server no call the seat_get_touch? <o:p></o:p> <o:p> </o:p> I also found it difficult to figure out how these three functions get called in the first place. These functions get assigned to pointer functions in wl_seat_interface structure and I cannot figure out where the pointer functions get called or reassigned. That is why I am asking for some help with how the seat_get_touch is called. <o:p></o:p> <o:p> </o:p> If you have anymore advice, I would be most grateful. <o:p></o:p> <o:p> </o:p> -Alexander Keller <o:p></o:p> <o:p> </o:p> <div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in"> From: Scott Moreau [mailto:oreaus@gmail.com] Sent: Monday, December 03, 2012 3:12 PM To: Keller Alexander-B42067 Cc: wayland-devel@lists.freedesktop.org Subject: Re: seat_get_touch not being called<o:p></o:p> </div> <o:p> </o:p> <o:p> </o:p> <div> On Mon, Dec 3, 2012 at 1:45 PM, Keller Alexander-B42067 <<a href="mailto:B42067@freescale.com" target="_blank">B42067@freescale.com</a>> wrote:<o:p></o:p> <div> <div> I have been trying to get my touchscreen inputs to work on Wayland, and everytime the screen is touched I get an error saying “couldn’t find resource.” I get that error because my seat->touch->resource_list is empty, and the function that writes to that list is seat_get_touch is not being called. What is unusual is that when I start the server, the server recognizes that a touch screen is plugged in and my driver is returning all the correct information. I was wondering exactly how the seat_get_touch function gets called so that I can populate the resource_list. Any help on this issue would be appreciated.

The only demo client I see that calls this function is simple-touch. Hope this helps. - Scott<o:p></o:p> </div> </div> <o:p> </o:p> </div> </body> </html>
