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..
Thanks,
Sathish

Hi,
I will update the following info to wiki as well. 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
layoutAPIs.
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

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 ??
