97 Reaction::UI::Controller
101 Base Reaction Controller class. Inherits from:
105 =item L<Catalyst::Controller>
106 =item L<Catalyst::Component::ACCEPT_CONTEXT>
107 =item L<Reaction::Object>
113 =head2 push_viewport $vp_class, %args
115 Creates a new instance of the L<Reaction::UI::ViewPort> class
116 ($vp_class) using the rest of the arguments given (%args). Defaults of
117 the action can be overridden by using the C<ViewPort> key in the
118 controller configuration. For example to override the default number
119 of items in a CRUD list action:
123 list => { ViewPort => { per_page => 50 } },
127 The ViewPort is added to the L<Reaction::UI::Window>'s FocusStack in
128 the stash, and also returned to the calling code.
134 =item L<Reaction::UI::Controller::Root>
135 =item L<Reaction::UI::Window>
139 TODO: explain how next_action as a scalar gets converted to the redirect arrayref thing
143 =head2 pop_viewport_to $vp
145 Call L<Reaction::UI::FocusStack/pop_viewport> or
146 L<Reaction::UI::FocusStack/pop_viewport_to> on
147 the C<< $c->stash->{focus_stack} >>.
149 =head2 redirect_to $c, $to, $captures, $args, $attrs
151 Construct a URI and redirect to it.
157 =item The name of an action in the current controller.
159 =item A L<Catalyst::Action> instance.
161 =item An arrayref of controller name and the name of an action in that
166 $captures and $args default to the current requests $captures and
167 $args if not supplied.
