Detailed Description

A list of viewable items.

This is a simplified take on the model-view design. Items can be any data structures (model) inherit from ItemBase. They are to be rendered (view) by render objects inherit from RenderBase. A tree or list can be used to store data of items. A Widget (such as ListView)can then keep a number of renders to display these data.
