Reaction::UI::Controller - Reaction Base Controller Class
package MyApp::Controller::Foo; use strict; use warnings; use parent 'Reaction::UI::Controller'; use aliased 'Reaction::UI::ViewPort'; sub foo: Chained('/base') Args(0) { my ($self, $ctx) = @_; $ctx->push_viewport(ViewPort, layout => 'foo', ); } 1;
Base Reaction Controller class, subclass of Catalyst::Controller.
Please not that this functionality is now deprecated.
Creates a new instance of the Reaction::UI::ViewPort class ($vp_class) using the rest of the arguments given (%args). Defaults of the action can be overridden by using the ViewPort key in the controller configuration. For example to override the default number of items in a CRUD list action:
ViewPort
__PACKAGE__->config( action => { list => { ViewPort => { per_page => 50 } }, } );
The ViewPort is added to the Reaction::UI::Window's FocusStack in the stash, and also returned to the calling code.

Call "pop_viewport" in Reaction::UI::FocusStack or "pop_viewport_to" in Reaction::UI::FocusStack on the $c->stash->{focus_stack}.
$c->stash->{focus_stack}
Construct a URI and redirect to it.
$to can be:
$captures and $args default to the current requests $captures and $args if not supplied.
The purpose of this method is to prevent memory leaks. It weakens the context object, often denoted $c, and passes it as the first argument to the sub{} that is passed to the make_context_closure method. In other words,
make_context_closure returns sub { $sub_you_gave_it->($weak_c, @_)
To further expound up this useful construct consider code written before make_context_closure was created:
on_apply_callback => sub { $self->after_search( $c, @_ ); } ),
This could be rewritten as:
on_apply_callback => $self->make_context_closure( sub { my $weak_c = shift; $self->after_search( $weak_c, @_ ); } ),
Or even more succintly:
on_apply_callback => $self->make_context_closure( sub { $self->after_search( @_ ); } ),
