Like on EPhysics, for soft bodies we create a whole bunch of evas objects proxing an evas object provided by the user(every triangle in a trimesh becomes a proxy), the user doesn`t know about the proxies and doesnt control their life cicle, callbacks are registered to the former evas object in that callback the user can then query EPhysics to make some operations on EPhysics bodies but with soft bodies the user may want to do something but in a specific proxy/slice. > 3) proxy event propagation is enabled with evas_object_image_source_events_set > 4) callback reacts differently based on which proxy triggered the event. > > > Regards.... > > On Sat, Nov 24, 2012 at 08:54:34PM +0900, ChunEon Park wrote: > > Btw, does it really source need to care about proxy in the events? > > Doesn't it enough to add callbacks to proxy directly if you need to care something? > > > > > > ------------------------------------ > > > > -Regards, Hermet- > > > > -----Original Message----- > > From: "Leandro Dorileo"<do...@pr...> > > To: "Carsten Haitzler"<ra...@ra...>; > > Cc: "Enlightenment developer list"<enl...@li...>; > > Sent: 2012-11-18 (일) 09:49:49 > > Subject: Re: [E-devel] [PATH] evas: add event source evas object > > > > Hi Raster, > > > > On Thu, Nov 15, 2012 at 02:25:38PM +0900, Carsten Haitzler wrote: > > > On Tue, 13 Nov 2012 11:49:47 -0200 Leandro Dorileo <dorileo>@profusion.mobi> > > > said: > > > > > > noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo! > > > > > > this breaks abi. > > > > > > never ADD structure members in the middle of a structure - add them at the > > > END... always! at least in public api's! > > > > > > Ok, attached goes a version considering the ABI thing.
