Hi, Daniel. Have you had a look at the image on
http://docs.enlightenment.org/auto/elementary/group__Widget.html? In
the inheritance schema, specialized smart data are stacked alltogether
in the widget's smart data struct. With that, widgets share data
common to its ancestors, as it should be. Having a variable of type
Elm_Layout_Smart_Data as the *1st* member of Elm_Bg_Smart_Data, one
can access the former struct's fields by casting the latter to it:
/* grab base object dimensions */
evas_object_geometry_get
(ELM_WIDGET_DATA(sd)->resize_obj, &bx, &by, &bw, &bh);
a code snippet taken from bg. See?
If you're still in doubt, just ask :)
Cheers,
