Overview

Here is the way the pages are generated

The general structure of each entity ( Form, Tree, Menu) is defined in the Model and Factory files. The html code is written in the HtmlRenderer files. They get the data from a context and put the appropriate html code in a buffer. The Wrappers make it easy to do and setup the rendering. The buffer is then used by the ScreenRenderer that generate the final page. The interaction between the different files is simply shown in the flow chart. ( Only a part of the interactions are shown.)
