Widget Structure

A widget consists of the following primary components:

  • An Escenic content type definition

  • A set of one or more themes, each consisting of CSS file and associated graphics files

  • A template, consisting of a set of JSP files. The template is internally organized as a controller and a set of one or more views.

This structure is reflected in a widget's folder tree:
