<H3> 7.12.3 Creating Custom AWS Components </H3>
<!--docid::SEC564::-->
<P>
Obviously, the components included with AWS will not cover
every single user's needs. Or, you may not like the way a
certain control actually works. Maybe you want it to glow faintly
when the mouse is over it. Or perhaps you don't like the way
command buttons look. AWS is designed
to be simple for component designers to use and extend. Without a rich set
of components, no windowing system is very interesting.
</P><P>
The first thing you need to know is that all components are
derived from the common base class `<SAMP>awsComponent</SAMP>'. This
component has built in handling for events and drawing. You
don't need to know anything about how internal event handling
happens; you just have to override the correct events. This base
component also has built in support for handling automatic
<EM>parameter delivery</EM>, and sinks and sources. The next few
sections detail the things that you should do to make a
good, robust, custom AWS component.
