120 Base Reaction Controller class. Inherits from:
124 =item L<Catalyst::Controller>
125 =item L<Catalyst::Component::ACCEPT_CONTEXT>
126 =item L<Reaction::Object>
132 =head2 push_viewport $vp_class, %args
134 Creates a new instance of the L<Reaction::UI::ViewPort> class
135 ($vp_class) using the rest of the arguments given (%args). Defaults of
136 the action can be overridden by using the C<ViewPort> key in the
137 controller configuration. For example to override the default number
138 of items in a CRUD list action:
142 list => { ViewPort => { per_page => 50 } },
146 The ViewPort is added to the L<Reaction::UI::Window>'s FocusStack in
147 the stash, and also returned to the calling code.

162 =head2 pop_viewport_to $vp
164 Call L<Reaction::UI::FocusStack/pop_viewport> or
165 L<Reaction::UI::FocusStack/pop_viewport_to> on
166 the C<< $c->stash->{focus_stack} >>.
168 =head2 redirect_to $c, $to, $captures, $args, $attrs
170 Construct a URI and redirect to it.
176 =item The name of an action in the current controller.
178 =item A L<Catalyst::Action> instance.
180 =item An arrayref of controller name and the name of an action in that
185 $captures and $args default to the current requests $captures and
186 $args if not supplied.
