Subject: major warning + cast cleanup.
X-Git-Tag: v1.0.0~5452
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=49101306eabd5cd60dfdb1ca73bf1231b9599bbf;p=platform%2Fupstream%2Felementary.git

major warning + cast cleanup.

 * casts: remove internal "Item" and use "Elm_XXXX_Item" for carousel,
   list, genlist and toolbar.

 * warning: fix const on lots of getter apis, the object should be
   const, and not the return! Of course lists that are returned and
   are not supposed to be modified are still returned as const, but
   maybe we should return iterators!

 * list/genlist: fix selected_set() to be a bit (marginally)
   faster. Do not operate if state has not changed and if it did
   changed we're sure we're not in the object->selected list.
