Yes I guessed that situation.
But it smells bad if source depends on the proxies.
And acutally I don't prefer to add that specific field in common mouse events
structure as possible.
My preferred was. set callbacks to each proxies and work separately.
and source, it works itself.
i.e) you wanna this maybe.
source_event_callback()
{
if (event_source == proxy1)
something_do1_for_proxy1();
else if (event_source == proxy2)
someting_do2_for_proxy2();
else
something_do_for_source();
something_do();
}
rather than, my preferred was this...
proxy1_event_call()
{
something_do1_for_proxy1();
set_somthing_to_source_if_required();
}
proxy2_event_call()
{
something_do2_for_proxy2();
set_something_to_source_if_required();
}
source_event_callback()
{
if (set_something_to_source)
something_do_for_source();
something_do();
}

Subject: Re: [E-devel] [PATH] evas: add event source evas object
Hi Hermet,
Think about an use case where a registered callback must reacts differently
depending on
which proxy triggered the event, like:
1) an evas object gets a callback registered to it
2) proxies are created
3) proxy event propagation is enabled with evas_object_image_source_events_set
4) callback reacts differently based on which proxy triggered the event.
Regards....
