Introduction

For a visual overview of what glPage is and does, a class hierarchy is diagrammed below.

Whereafter a entity diagram is shown when entities are preferred over objects.

Finally the theme is visual depicted suggesting it is a package. Somehow it actuallay is, because it consists of resources and layouts (renamed to outline).

Class Hierarchy

The template class is split into a templet class, doing all the parsing, and a template class doing file access and caching. The templet accepts a parameter as the template text and therefor cannot be 'finished'. The layout class extends template to hold the layout-nodes. The page class is in fact a controller and contains static variables, so it cannot instantiate.

Entity Diagram

Clearly shown that the new style is building a tree from page -> layout -> template.

The template entity can be used outside the tree too. There is not Templet entity since it is just a tool.

Theme & Skins

GlPage 2.png

The theme is depicted as a package that contains the components outline and skin. The term outline is chosen to be different from the term layout.

A theme consists of resources (not shown) like stylesheets, scripts, images (like icons, backgrounds or overlays) and the like.
