plone.app.viewletmanager 5.0.0

Configurable viewlet manager

Introduction

by Florian Schulze <[e-mail]>.

This component expects you to register storage.ViewletSettingsStorage as a local utility providing IViewletSettingsStorage (CMFPlone does this). The viewlet manager in manager.OrderedViewletManager can then get the filter and order settings. These settings can be configured by 3rd party products and TTW to customize the viewlets per skin.

• Use JS calls to handle show/hide/move actions instead of forcing a page reload. Will fall back to old method if JavaScript is not available. [esteele]

1.2.2 - 2009-03-07

• Specified package dependencies. [hannosch]

• Made the manager code more tolerant and not fail when no storage is found. [hannosch]

• Made the @@manage-viewlets screen use the ‘managedPortlet’ CSS class instead of ‘portlet’, so it’s more usable with a custom theme. This closes http://dev.plone.org/plone/ticket/8391. [davisagli]
