Thanks you very much! New to wayland, so a lot to learn.

Hi Han,

In ivi-shell architecture, there are controller plugins which controls the 
layout of surfaces on the display. The controller plugins are using 
ivi_layout_interface to do that.
In weston repository, we have hmi-controller plugin which is good for demo 
purposes. But it is not suitable for production use-cases.

Please check https://github.com/GENIVI/wayland-ivi-extension. There, we have 
ivi-controller plugin which enables you to control the layout via ivi_wm 
protocol.
You can use ivi-wm protocol directly in your Window Manager app, or you can use 
ilmControl library, or you can use LayerManagerControl command line tool to 
control the layout of surfaces.

Hi Han,

In that case, you should probably use a protocol designed for embedded surface 
layout, like ivi-shell, rather than xdg-shell. Embedded, static-size display is 
a very different use case than a modern desktop system which requires hotplug 
and multimonitor layouts.

Hi Han,

Allowing yourselves to place multiple windows where you want it then isn't 
going to solve that problem, since users can still drag them around, minimize 
them, etc. Multiprocess rendering is a bit tricksy, and there's no standardized 
way to do it right now. The traditional technique is to build your own Wayland 
compositor inside your application, which is a bit heavyweight, and then use 
wl_subsurface to composite the results. This is what e.g. WebKit2's 
architecture does, and it's something I've tried to implement in the past [0]. 
As the scope of a Wayland compositor becomes larger and larger over time, I 
think this is starting to become a bit impractical. It might be worth looking 
into a multi-process buffer-sharing protocol as a Wayland extension, since it's 
a use case that keeps coming up.

Then you want to probably use process to process buffer sharing (e.g. like a
nested wayland compositor), and maybe subsurfaces. Then you have a main process
that acts as a gateway for other processes and their buffers and input etc. and
this process manages your policies within its window and relative positioning
space.

Never rely on the system compositor for this. What if the system compositor
didn't have a rectangular screen but displays on a globe? Or a hemisphere? Or
it wrapped the display around a 3d bunny rabbit? What if it was a compositor
for a mobile-like UI where it decided every app window is to be "fullscreen"
and mutually exclusive to other apps, displaying only 1 at a time? Relying on
and demanding global positioning files in the face of implementing man common
UI policies you see today across many devices. Wayland (and xdg-shell) are
designed to be as agnostic as possible to the final display policy and thus
limit things like positioning to only be subsurface based (relative to main
surface).

[Even that issue appears offtopic to me, here a hint: you might use a
IPC and render into a common canvas from all your rendering processes.
How you update is then up to the application showing the window (once a
frame is finished or after each process send its part).]

We are running a multi process application. And GUI is act as a transparent top 
layer. All other process rendering by them self underneath. So its important 
for other process to place the window at right potion.

Maybe you are after a full screen application then. With that you should be 
able to decide about the positioning on the whole output.

Hi Han,

You cannot position surfaces absolutely using the traditional xdg-shell 
protocol. However, for embedded cases, there are protocols like ivi-shell which 
provide that functionality.

It isn't. Can you share why you want to position a window at a specific point 
in the screen? What's your use-case?

that is the intended design. it's a very good thing not allowing clients to
arbitrarily position themselves on a screen. a very good idea. wayland has
gotten it right here (and ivi-shell i think is just being wrong and not
understanding the mountain of history behind such a decision to disallow
manual explicit positioning).

Thanks Jasper. Do u know if there's a demo i can learn from? Currently i am 
creating a bigger surface bigger than screen size. and make subsurface so i can 
posion them as i want. Really don't think its a good way to do it.
