Plone “events”
Recently I was looking for a list of all events available in plone. By ‘events’ what I actually mean is:
Zope provides an events system. Various components (e.g the standard add and edit forms) notify any number of event subscribers (also known as event handlers) of a particular event.
So these are ‘events’ you can subscribe to and trigger custom code when they are fired. I wasn’t able to find a complete list so I’ve decided to compile one myself:
From zope.lifecycleevent.interfaces:
- IObjectCreatedEvent
- IObjectCopiedEvent
- IObjectModifiedEvent
From Products.Archetypes.interfaces:
- IObjectInitializedEvent
- IWebDAVObjectInitializedEvent
- IObjectEditedEvent
- IWebDAVObjectEditedEvent
- IEditBegunEvent
- IEditCancelledEvent
From zope.app.container.interfaces:
- IObjectMovedEvent
- IObjectAddedEvent
- IObjectRemovedEvent
- IContainerModifiedEvent
From Products.CMFCore.interfaces:
- IWorkflowActionEvent
- IActionWillBeInvokedEvent
- IActionRaisedExceptionEvent
- IActionSucceededEvent
From Products.DCWorkflow.interfaces:
- ITransitionEvent
- IBeforeTransitionEvent
- IAfterTransitionEvent
