Re: faster development with xul

Installer DeLux doesn't require that each form requires a new Java class
to support it.  On the down side, it assumes certain simplifications and
conventions to make it happen.  However, depending on your app, the
approach might work.  A "shell" class wraps the xul form to provide
common functionality like window closing handling and callbacks.  A
display manager class dynamically instantiates each xul form, ties the
decorations to the forms (icons, window titles, menus), and associates
actions to each form.  Actions are created dynamically from xul files
where the most commonly used action is the "DelegatedAction" which
passes the execute() on to a custom handler.  Yes, this is an additional
layer of indirection, however, it allows the manager to reload updated
xul files at will.
