2.2 The FrameWork Classes</A>
</H2>
<P>
The Kiwi framework is made up of a set of classes and some helper
functions that are used to define the behavior of your application.
The Kiwi classes are organized into the following groups:
<P>
<UL>
<LI><tt class="class">Views</tt>, which represent the graphical display; a View defines
an interface's widgets and their layout.
</LI>
<LI><tt class="class">Controllers</tt>, which handle signals generated by the user
interacting with the widgets in a View.
</LI>
<LI><tt class="class">Delegates</tt>, which are classes that combine the features of
a View and a Controller.
</LI>
<LI><tt class="class">Models</tt>, which are mixins your domain object can
inherit from to take advantage of special functionality.
</LI>
<LI><tt class="class">Proxies</tt>, special types of Delegate designed to implement
forms. Proxies attach themselves to an instance, and transparently
modify this instance as the user interacts with the widgets in its
interface.
</LI>
</UL>
<P>
Of these, <tt class="class">Controllers</tt> and <tt class="class">Models</tt> do not implement user
interfaces themselves, and are used together with one of the different
user interface (UI) classes.
<P>
<B>A special note:</B> When using a white-box framework, it is very
important to take care when defining names in the inherited classes to
avoid clobbering names defined in the base classes you inherit from. It
is useful to read through the
<em class="citetitle"><a
href="http://www.async.com.br/projects/kiwi/api/"
title="API
documentation"
>API
documentation</a></em> and check for naming conflicts, and to understand which
hooks might be interesting to reimplement. If you find something in your
code is behaving very strangely, this could be one of the first things
to check.
