You can take ICO home screen as an example. https://review.tizen.org/git/?p=profile/ivi/ico-uxf-weston-plugin.git;a=summary<https://review.tizen.org/git/?p=profile/ivi/ico-uxf-weston-plugin.git%3ba=summary> https://review.tizen.org/git/?p=profile/ivi/ico-uxf-homescreen.git;a=summary<https://review.tizen.org/git/?p=profile/ivi/ico-uxf-homescreen.git%3ba=summary> Thanks, Ning From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Li, Hao H Sent: Tuesday, February 25, 2014 4:56 PM To: Yang Andy; [email protected]<mailto:[email protected]> Subject: RE: How to use wayland/weston on Tizen IVI 3.0 EFL is a set of components that can be used to build graphical applications. Wayland is a protocol that specifies the communication between the display server (called Wayland compositor) and its clients. You can reference to http://cdn.download.tizen.org/misc/media/conference2013/slides/TDC2013-How_to_Embrace_Wayland_for_Tizen.pdf (page 21 etc) For applications that use Ecore_Evas directly set the environment variable ECORE_EVAS_ENGINE to either wayland_egl or wayland_shm depending on whether you wish to use the SHM based interface with software rendering or use EGL. For applications that use Elementary set the environment variable ELM_ENGINE to wayland_egl or wayland_shm as above. Sample code can be got from src\lib\ecore_evas\ecore_evas.c (https://review.tizen.org/git/?p=platform/upstream/ecore.git;a=summary<https://review.tizen.org/git/?p=platform/upstream/ecore.git%3ba=summary>) etc From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Yang Andy Sent: Tuesday, February 25, 2014 4:45 PM To: [email protected]<mailto:[email protected]> Subject: How to use wayland/weston on Tizen IVI 3.0 Hi everyone.
