Description

Subroutines/Methods

COMPONENT

Called by Catalyst when the application starts it sets the default action from global config and sets up the list of available skins

access_check

$state = $c->model( q(Navigation) )->access_check( @args );

Expects to be passed the stash ($c->stash), a key to search in the stash ($args[0]) and a level or room to search for ($args[1]). It returns 0 if the ACL on the requested level/room permits access to the current user. It returns 1 if no ACL was found. It returns 2 if the current user is unknown and the level/room's ACL did not contain the value any which would permit anonymous access. It returns 3 if the current user is explicitly denied access to the selected level/room

This method is called from /add_nav_menu (via the /allowed method which negates the result) to determine which levels the current user has access to. It is also called by /auto to determine if access to the requested endpoint is permitted

It could also be used from an application controller method to allow the display logic to display content based on the users identity

access_control_form

$c->model( q(Navigation) )->form( $namespace, $name );

Stuffs the stash with the data for the form that controls access to levels and rooms

add_header

$c->model( q(Navigation) )->add_header;

Calls parent method. Adds main and tools menu data. Adds quick link data

Calls "add_nav_menu". This is the main navigation menu

Calls "add_utils_menu"

Calls add_quick_links. Quick links appear in the header and are selected from the rooms config items if the quick_link element is set. It's numeric value determines the sort order of the links

add_help_menu

Help menu options

Adds some useful debugging info to the footer

add_menu_back

$c->model( q(Navigation) )->add_menu_back( $args );

Adds a history back link to the main navigation menu

add_menu_blank

$c->model( q(Navigation) )->add_menu_blank( $args );

Adds some filler to the main navigation menu

add_menu_close

$c->model( q(Navigation) )->add_menu_close( $args );

Adds a window close link to the main navigation menu

add_nav_menu

$c->model( q(Navigation) )->add_nav_menu;

Returns the data used to generate the main navigation menu. The menu uses a Cone Trees layout which has been flattened to produce a visual trail of breadcrumbs effect, i.e. Home > Reception > Tutorial

$links = $c->model( q(Navigation) )->add_quick_links;

Returns the data used to display "quick" navigation links. Caches data on first use. These usually appear in the header and allow single click access to any endpoint. They are identified in the configuration by adding a quick_link attribute to the rooms element. The quick_link attribute value is an integer which determines the display order

add_sidebar_panel

Adds a sidebar panel containing a tree widget that represents all the action available in the application (another sitemap)

add_tools_menu

Utility menu options

add_tree_panel

$c->model( q(Navigation) )->add_tree_panel;

Calls "_get_tree_panel_data" and creates a tree widget using the data. Implements the navigation sidebar

add_utils_menu

$c->model( q(Navigation) )->add_utils_menu;

Returns the stash data for the utilities menu. This contains a selection of utility options including: toggle runtime debugging, toggle footer, skin switching, context sensitive help, about popup, email feedback and logout option. Calls "add_help_menu" and "add_tools_menu"

allowed

$bool = $c->model( q(Navigation) )->allowed( @args );

Negates the result returned by "access_check". Called from "add_nav_menu" to determine if a page is accessible to a user. If the user does not have access then do not display a link to it

app_closed_form

$c->model( q(Navigation) )->app_closed_form;

Allows administrators to authenticate and reopen the application

room_manager_form

$c->model( q(Navigation) )->room_manager_form( $namespace, $name );

Allows for editing of the level and room definition elements in the configuration files

select_this

$c->model( q(Navigation) )->select_this( $menu_num, $order, $widget );

Make the widget the selected menu item

sitemap

$c->model( q(Navigation) )->sitemap;

Displays a table of all the pages on the site

_get_tree_panel_data

$data = $c->model( q(Navigation) )->_get_tree_panel_data;

Called by "sitemap" this method generates the table data used by HTML::FormWidgets's Tree subclass

_get_sitemap_data

$data = $c->model( q(Navigation) )->_get_sitemap_data;

Called by "sitemap" this method generates an array of hash refs used by HTML::FormWidgets's TabSwapper subclass

_get_sitemap_table

$data = $c->model( q(Navigation) )->_get_sitemap_table( $ns );

Called by "_get_sitemap_data" this method generates the table data used by HTML::FormWidgets's Table subclass

$self->_push_menu_link( $name, $order, $ref );

Pushes an anchor widget $ref onto a menu structure

_unshift_menu_item

$self->_unshift_menu_item( $name, $order, $widget );

Unshift an anchor widget onto a menu structure
