Hi,
From: IVI [mailto:ivi-boun...@lists.tizen.org] On Behalf Of karthik karthik Sent: Saturday, July 26, 2014 8:43 PM To: ivi@lists.tizen.org Subject: Re: Questions on weston-ivi-shell Hi, Thanks for the reply, I have a few doubts. Can you clarify them for me. 1) "Additionally, supporting wl_shell on ivi-shell is temporary.".. Does this mean the following. Currently, wl_shell, the default shell in wayland/weston is supported on tizen.. But outside of tizen, there is a ivi_shell similar to desktop_shell that is used.. Can you point me to some documentation on wl_shell so that I can understand it better ?? 2) I am trying to modify weston-ivi-shell, a bit. Instead of launching application binaries, I want to launch HTML5 web apps. I took the ICO Homescreen as example and launching the apps using tizen application api's namely "aul_app_launch". When I launch these applications, I am facing issues in IVISurfaceCreator.. When I run the program, the api returns a success on launch.. What I dont get to see application on the display each time.. If I look at the log, I could see this print statement printed 10 times.. printf("IVISurfaceCreator: Search of native handle was ended.\n" " But no surface was created.\n" " Retry get_native_handle.\n"); Is there a reason why this is happening.. Can you help me with this..

Additionally, supporting wl_shell on ivi-shell is temporary. If application supports ivi_application.create_surface, you don’t have to use IVISurfaceCreater to map wl_surface to Global ID. If you want to show application only supports wl_shell, IVISurfaceCreater is useful tool. a) Launch application using system calls. The application on launch, will render the graphics on the wayland surface. Steps 1 and 2 mentioned above will done in the application itself. IVISurfaceCreator --help Usage: IVISurfaceCreator <Process ID> <Window Title> <IVI-Surface ID> IVISurfaceCreator is a Tool to map wl_surface to GlobalID: <IVI-Surface ID>. “Window Title” is set by using wl_shell_surface::set_title. E.g. Weston-flower names its title as “Flower”. If you set NULL to the parameter, IVIsurfaceCreator will map the oldest wl_surface to the ID. As usual, Weston client example create only one wl_surface in its process. The title is not so important parameter. After that, you can use <IVI-Surface ID> to control the wl_surface by using ivi layout APIs. If you want to get notification when an application create wl_shell_surface, you can use the following event in ivi_application.xml, extension event for TIZEN IVI only. <event name="wl_shell_info"> <arg name="pid" type="int"/> <arg name="title" type="string" allow-null="true"/> </event> BR, Nobuhiko From: IVI [mailto:ivi-boun...@lists.tizen.org] On Behalf Of karthik karthik Sent: Wednesday, July 23, 2014 1:56 AM To: ivi@lists.tizen.org Subject: Questions on weston-ivi-shell Hi, In the process of trying to understand layer management, I had understood the following. Need some help to check whether I am right with these understanding. Steps :- To put an image file on to a layer :- 1) Use wl_compositor_create_surface to create a wayland surface. 2) Write the image data on to the wayland surface. 3) Use ivi_application_surface_create api to tie the wayland surface with the Global ID. 4) Now to add it to a Layer, a) Use the global ID to extract the surface using the API weston_layout_getSurfacefromID. b) The resultant surface is added to the layer using the API weston_layout_addSurfacetoLayer. To put an application on to a layer :- a) Launch application using system calls. The application on launch, will render the graphics on the wayland surface. Steps 1 and 2 mentioned above will done in the application itself. b) Launch IVISurfaceCreator. The Global ID is passed via arguments to the IVISurfaceCreator. c) IVISurfaceCreator calls the ivi_application_surface_create api's to tie the wayland surface with the Global ID. d) Now to add it to a layer, it is similar to step 4 mentioned above.. Is this understanding correct ?? Thanks,
