(unless u are spending large amounts of cpu just handling the input event stream and making ecore events out of it). so you get ecore events - fine, but evas isnt calling back for all events... that shouldn't happen (unless position hasn't changed etc.) > Regards > HariHaraSudhan > > On Thu, Nov 3, 2011 at 6:34 PM, HariHara Sudhan <h...@emo2.com> wrote: > > Sent from my Windows Phone > > From: Carsten Haitzler > > Sent: 11/3/2011 4:20 PM > > To: Enlightenment developer list > > Cc: HariHara Sudhan > > Subject: Re: [E-devel] Ecore_processing mtdev events > > On Wed, 2 Nov 2011 19:38:09 +0530 HariHara Sudhan <h...@emo2.com> said: > > > >> Hi all, > >> I've lately added mtdev to receive touch events and process them as > >> ecore mouse events( as mpx). > >> i get the window id by the original mouse movements and use that id > >> for passing touch events for that window. > >> > >> i get the slot id from mtdev.
