NAME
       Gimp::basewidget - pragma to declare the superclass of a
       gtk widget

SYNOPSIS
         use Gimp::basewidget 'superclass';

       e.g.

         use Gimp::basewidget Gtk::Button;


DESCRIPTION
       This pragma can (but does not need to) be used to declare
       the current package as a childclass of an existing Gtk
       widget class. The only "import tag" must be the name of
       the existing superclass.

       The module automatically registers a subtype, calls a spe-
       cial callback at gtk initialization time and provides
       default implementations for some common methods (the list
       might grow in the future to enhance settor/gettor func-
       tionality).

       The following methods are provided. All of them can be
       overriden in your package.

       new A simple generic new constructor is provided. It will
           simply call "Gtk::Object::new" with all the provided
           arguments.

       GTK_INIT
           This callback is called as early as possible after gtk
           was initialized, but not before. This can be used to
           register additional subtypes, argument types etc. It
           is similar to GTK_CLASS_INIT.

       GTK_CLASS_INIT
           Unlike the standard Gtk-callback of the same name,
           this method can be omitted in your package (while
           still being a valid Widget).

       GTK_OBJECT_INIT
           This callback can also be omitted, but this rarely
           makes sense ;)

BUGS
       This was a pain to implement, you will not believe this
       when looking at the code, though.
