How Themes Work

EWL relies on a graphical layout engine called Edje. Edje allows a themer to layout images, in fairly advanced ways and provides methods for animation and changing of images based on various signals. EWL uses an Edje collection per-widget and has a set of keys for specifying which widget uses a specific collection. Information about using Edje can be found at the project page. The remainder of this section concentrates specifically on how EWL interacts with Edje.

The keys to lookup the group name for the widgets are top level data keys in the themes edje file. Each widget looks up it's group name based on the heirarchy it is placed inside other containers.
