Layout Management
=================
($Id$)
Let's start with some basic setup; the traversable adapter is needed for
rendering the page templates.
>>> from zope import component
>>> from zope.interface import Interface
>>> from zope.traversing.adapters import DefaultTraversable
>>> component.provideAdapter(DefaultTraversable, (Interface,))
For testing we define a simple content class.
>>> class Document(object):
... text = ''
The layout management is controlled by a global utility, the layout
manager.
>>> from cybertools.composer.layout.base import LayoutManager, LayoutInstance
>>> from cybertools.composer.layout.interfaces import ILayout
>>> manager = LayoutManager()
>>> component.provideUtility(manager)
The layouts themselves are also specified as utilities that are automatically
registered when we import the modules they are defined in.
>>> from cybertools.composer.layout.browser import default
>>> from cybertools.composer.layout.browser.liquid import default
In addition we have to provide at least one layout instance adapter that
connects a layout with the client object.
>>> component.provideAdapter(LayoutInstance, (object,))
Browser Views
=============
>>> from cybertools.composer.layout.browser.view import Page
>>> from zope.publisher.browser import TestRequest
>>> page = Page(Document(), TestRequest())
>>> page()
u'<!DOCTYPE ...>...<html ...>...</html>...'
