118 | |
119 | Base Reaction Controller class. Inherits from: |
120 | |
121 | =over 4 |

124 | =item L<Catalyst::Component::ACCEPT_CONTEXT> |

129 | =head1 METHODS |
130 | |
131 | =head2 push_viewport $vp_class, %args |
132 | |
f1cd5548 |
133 | Creates a new instance of the L<Reaction::UI::ViewPort> class |
134 | ($vp_class) using the rest of the arguments given (%args). Defaults of |
135 | the action can be overridden by using the C<ViewPort> key in the |
136 | controller configuration. For example to override the default number |
137 | of items in a CRUD list action: |
138 | |
139 | __PACKAGE__->config( |
140 | action => { |
141 | list => { ViewPort => { per_page => 50 } }, |
142 | } |
143 | ); |
144 | |
145 | The ViewPort is added to the L<Reaction::UI::Window>'s FocusStack in |
146 | the stash, and also returned to the calling code. |
