98 | =head2 push_viewport $vp_class, %args |
99 | |
f1cd5548 |
100 | Creates a new instance of the L<Reaction::UI::ViewPort> class |
101 | ($vp_class) using the rest of the arguments given (%args). Defaults of |
102 | the action can be overridden by using the C<ViewPort> key in the |
103 | controller configuration. For example to override the default number |
104 | of items in a CRUD list action: |
105 | |
106 | __PACKAGE__->config( |
107 | action => { |
108 | list => { ViewPort => { per_page => 50 } }, |
109 | } |
110 | ); |
111 | |
112 | The ViewPort is added to the L<Reaction::UI::Window>'s FocusStack in |
113 | the stash, and also returned to the calling code. |
