NAME

       Graphics::Primitive::Container - Component that holds other Components

DESCRIPTION

       Containers are components that contain other components.  They can also hold an instance
       of a Layout::Manager for automatic layout of their internal components. See the
       Component's Lifecycle Section for more information.

SYNOPSIS

         my $c = Graphics::Primitive::Container->new(
           width => 500, height => 350,
           layout_manager => Layout::Manager::Compass->new
         );
         $c->add_component($comp, { meta => 'data' });

METHODS

   Constructor
       new Creates a new Container.

   Instance Methods
       add_component ($component, [ $constraint ])
           Add a component to the container.  Returns a true value if the component was added
           successfully. A second argument may be required, please consult the POD for your
           specific layout manager implementation.

           Before the component is added, it is passed to the validate_component method.  If
           validate_component does not return a true value, then the component is not added.

       clear_components
           Remove all components from the layout manager.

       component_count
           Returns the number of components in this container.

       component_list
           Returns this Container's ComponentList.

       find_component
           Returns the index of the first component with the supplied name.  Returns undef if no
           component with that name is found.

       get_component
           Get the component at the specified index.

       get_constraint
           Get the constraint at the specified index.

       get_tree
           Returns a Forest::Tree object with this component at the root and all child components
           as children.  Calling this from your root container will result in a tree
           representation of the entire scene.

       prepare
           Prepares this container.  Does not mark as prepared, as that's done by the layout
           manager.

       remove_component
           Removes a component.  Components must have names to be removed.  Returns an arrayref
           of removed components.

       validate_component
           Optionally overridden by an implementation, allows it to deem a component as invalid.
           If this sub returns false, the component won't be added.
