Hey, I want to check if a given part's type is SWALLOW before using it to
swallow an object.
I couldn't find a way to do it without using Edje_Edit.h. Sice this is for the
Edje book I wouldn't want to encourage Edje_Edit for regular application
development. Or is promoting the usage of Edje_Edit in applications a good
idea?
My approach was to add a new function to Edje that return the part type as an
unsigned char (like Edje_Edit does) and to move the macros EDJE_PART_TYPE_*
from edje_private.h to Edje.h .
I attached a patch showing the changes.
Thanks and good bye.
