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 special callback at gtk initialization time and provides default implementations for
       some common methods (the list might grow in the future to enhance settor/gettor functionality).

       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 sub-
	   types, 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.
