From 82eab90f7842cefa60fbeaa000acc4ae71f7ff8b Mon Sep 17 00:00:00 2001 From: Nobuhiko Tanibata Date: Mon, 27 Oct 2014 11:17:51 +0900 Subject: [PATCH 07/15] clients: a reference implementation of UI client how to use ivi-hmi-controller. - introduces ivi-shell-user-interface.c This is launched from hmi-controller by launch_hmi_client_process and invoke a client process. The basic flow is as followed, 1/ process invoked 2/ read configuration from weston.ini. 3/ draw png file to surface according to configuration of weston.ini 4/ all parts of UI are ready. request "UI_ready" to draw UI. 5/ Enter event loop 6/ If a surface receives touch/pointer event, followings are invoked according to type of event and surface 6-1/ If a surface to launch ivi_application receive touch up, it execs ivi-application configured in weston.ini. 6-2/ If a surface to switch layout mode receive touch up, it sends a request, ivi_hmi_controller_switch_mode, to hmi-controller. 6-3/ If a surface to show workspace having launchers, it sends a request, ivi_hmi_controller_home, to hmi-controller. 6-4/ If touch down events happens in workspace, ivi_hmi_controller_workspace_control is sent to slide workspace. When control finished, event: ivi_hmi_controller_workspace_end_control is received.
