Hi,

I cannot answer that question really, and I doubt if anyone can without
tracing through the code. It could also be an oversight, that code is
demo quality and might use some cleaning up.

It's not a public nor a stable protocol, so if there is no use for the
argument, maybe it's unneeded and can be removed. That protocol is an
implementation detail of hmi-controller which itself is just a demo of
how to use ivi-layout. Both users of the protocol are in the weston
repository: ivi-shell/hmi-controller.c and
clients/ivi-shell-user-interface.c.

Why are you interested? Are you looking to improve the hmi-controller
and the helper client code?


Thanks,
pq
