=head1 NAME
-Reaction::UI::WidgetClass
+Reaction::UI::WidgetClass - Create a new widget class
=head1 DESCRIPTION
+Turns the importing package into a widget class. It will export:
+
+=over 4
+
+=item All of L<Moose>
+
+=item All of L<Reaction::Class>
+
+=item L<strict> and L<warnings>
+
+=item See L</EXPORTS> for this package's own exports
+
+=back
+
+It will also set the value of C<default_base> as new superclass. The default is
+C<Reaction::UI::Widget>.
+
+=head1 EXPORTS
+
+=head2 over
+
+ over $collection
+
+Used in combination with L</render> to render a fragment for a series of values:
+
+ render fragment_name => over [1, 2, 3];
+
+=head2 render
+
+ render $fragment_name;
+ render $fragment_name, $over;
+
+With only the fragment name as argument, it renders that fragment. If an C<$over>
+collection is specified with the L</over> keyword, the fragment is rendered once
+for every value in the collection. The value will be accessible in the topic
+argument C<_>.
+
+=head2 arg
+
+ arg $arg_name, $arg_value;
+
+Sets the fragment argument C<$arg_name> to C<$arg_value>;
+
+=head2 localized
+
+ localize $value;
+
+Calls the view's C<localize> method to localize the passed value.
+
+=head2 call_next
+
+ call_next;
+
+Calls the parent fragment.
+
+=head2 event_id
+
+ event_id $event_name;
+
+Fetches the event id for the event C<$event_name> from the viewport via its C<event_id_for>
+method.
+
+=head2 event_uri
+
+ event_uri \%events;
+
+Returns an L<URI> object with the event ids corresponding to the keys in the C<%events>
+argument and the values being the values of the hash reference.
+
+=head2 attrs
+
+ attrs \%attrs;
+
+Builds a string of rendered element attributes out of the C<%attrs> hash reference argument.
+
+=head2 implements
+
+ implements fragment foo { ... };
+ implements bar => sub { ... };
+
+Implements a method or a fragment in the widget class.
+
+=head2 fragment
+
+ fragment foo { ... };
+
+Creates a new fragment named C<foo> with a implementation in the block.
