Just to clarify this remark a bit.. All this really means, in this
particular case of edje, is a means by which an edje object would setup,
on each of its member parts, a function that would allow for changing
the part description suitably to reflect the state of the member object..
eg. if a member obj's color is changed (via the evas api), then it would
call a color-inform kind of callback function which would end by basically
saying: have the parent edje smart find the part description corresponding
to that member obj (if possible) and change the color state there to be
the member's current color -- ie. a method to edit *some* of the edje
parts states via 'parent inform' kinds of callbacks. One could also
possibly use it to override things.. and in general it could be used for
many things.
Anyway, not saying that would be useful or desirable.. just thought
I'd mention it. :)
