Configurable viewlet manager

Project description


by Florian Schulze <>.

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.

2.0.11 (2018-01-30)

Bug fixes:

  • Add Python 2 / 3 compatibility [jensens]

2.0.10 (2016-08-10)

2.0.6 (2014-07-10)

  • Use the !important directive for the .hide and .show CSS declarations on the @@manage-viewlets view. Twitter Bootstrap is using !important on these class names too, which made the viewlet management view unusable. [thet]

2.0.5 (2014-02-23)

  • Do not catch conflict errors and keywordinterrupt in viewlet manager. We can programmatically setup the exceptions that are not caught. [thomasdesvenain]

  • Add [WouterVH]

2.0.2 - 2011-01-11

  • Depend on Products.CMFPlone instead of Plone. [elro]
  • Explicitly unregister IViewletSettingsStorage utility to prevent test bleed. [esteele, cah190]

2.0.1 - 2010-07-18

  • Update license to GPL version 2 only. [hannosch]

2.0 - 2010-07-15

  • Silence Nothing to import / export. log messages. [hannosch]

2.0b5 - 2010-06-03

  • Removed duplicated class statement in for compatibility with Chameleon. [pilz]

2.0b4 - 2010-05-01

2.0a1 - 2009-11-14

  • Added translations for Show/Hide labels in @@manage-portlets view: label_show_item and label_hide_item. These msgids are shared with @@manage-viewlets view to show/hide viewlets. This closes [naro]
  • 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]

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

1.2 - 2008-03-09

  • Separated the base functionality and the parts necessary for TTW customization into two classes, so we can use this manager in the html head. [fschulze]
  • Fix a syntax error in the export/import code [wichert]
