/**
|
|
* PageView - handles the content block placement for a single page in Quasi.
|
|
*
|
|
* This class is the manager for placing content blocks associated with a Page.
|
|
* It sets up the ContentBlocks according to some default areas as defined in the
|
|
* block_location_type table in the database, These are currently hard coded to offer
|
|
* a default generic layout with a header, two side bars, a center content area and
|
|
* a footer. Extra divs are also provided for extra flexibility. All divs loaded by this
|
|
* class are contained within the master container div (see the template).
|
|
*
|
|
* You can modify the default layout via the style sheet associated with each Page
|
|
* - the style sheet to use for a page can be set via the Quasi CMS administrative interface.
|
|
* It is also not difficult to change the default areas - simply edit the template and ensure
|
|
* that the associated div CSS id names are in the block_location_type table and then
|
|
* you can associate ContentBlocks with those areas (again through the admin interface).
|
|
*
|
|
*NOTE: One course of development would be to subclass this for page types. This
|
|
* is already in the database, but it is not used yet - an architectural decision to be made ...
