Subject: elementary/layout - added theme changed hook
X-Git-Tag: v1.0.0~2530
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3721e4e153aeb914463cbc6f566b9bd91627fc56;p=platform%2Fupstream%2Felementary.git

elementary/layout - added theme changed hook

Because the user can use their' own edj objs and call the signals for the edj objs,
They have a responsibility to reset the status of the edj objs when layout theme is changed.

This "theme,changed" signal provides to user a chance to reset (signal-emit) again.
