Viewlets are not portlets! Portlets are much more restrictive and the industry
has a very specific meaning for the term, which differs from both, Plone's
and CPS skins', usage of the term.
Actually I've looked into creating a generic "viewlet" portlet that
would make it possible to reuse viewlets in cpsskins (for instance by
using the visual portlet editor). A feature that is missing is that
there is no easy way to find the list of registered viewlets. A viewlet
lookup mechanism would be needed, for instance a utility that returns a
list vocabulary items with viewlet's name and the factory.
also something that seems strange is that some viewlets are dependent on
see for instance: zope/app/boston/viewlets/toolbar:
"""I18n info viewlet."""
def macros(self, name):
return self.manager.macros(name) <<<<<<<<<<
def menus(self, menuId):
return getMenu(menuId, self.context, self.request)
So if I want to render a toolbar viewlet I need to instanciate the
corresponding viewlet manager. I would understand this if I wanted to
render all viewlets in a given area of the page, but if I want to render
just one viewlet?
Basically it introduces a cycle in the design: viewlet managers depend
on viewlets and viewlets depend on viewlet managers to be rendered.
