I was trying to create an application-level logical event class, and I
realized that the plugin could provide a wizard to create the class
and its associated handler.  Since this task invariably requires the
author to create three related Java files, and since most of the code
is boilerplate, a wizard could do all the mechanical work.  The wizard
would ask for:

1. A package name,
2. An event class name fitting the pattern XyzEvent.

The plugin would also create a handler interface named XyzHandler.  It
would contain a method with signature

public void onXyz(XyzEvent event);

This method would also be invoked in the generated dispatch() method
of the new event class.

Finally, the plugin would create a client interface named
HasXyzHandlers extending HasHandlers.  The plugin would also have the
standard option to add Javadoc comments and header comments.

I could also see a modification to the module plugin; the plugin could
give the author the option to create the module in a new Eclipse
project, which would necessitate changes to the .classpath
and .project files.

Respectfully,
Eric Jablow
