Hi everyone,
I couldn't get this to work, and by looking at the code it did not seem to
be implemented, so here's a patch that allows sending signals to a box's
items.
It's quite useful when you populate a box in edje through items{} and can't
access the evas_object directly or just want to do it in Edje.
This does not change the current behavior to get messages from the item
itself.
It's used that way :
emit => (signal = "boxname:idx:signal", source = "whatever")
where idx is an integer (starting at 0 of course).
The code is quite raw and may need a little reviewing/cleaning, but it seems
to work as far as I've tested.
