All Actions must be derived from the Action base class, and should implement the available and execute methods.

Refer to the built-in Actions in the resources/scripts/actions directory for examples.


These attributes are read-only.

Name Description
actionType The Action Type
extension If the Action implements an importer or exporter, the file extension the action works with
id The Action class name
label The Action label that appears in the Actions menu


Name Description
__init__(label, menu=None, type=Action, extension=None) Constructor - Initializes the base class. The menu can be listed separately or prefixed to the label with the '|' character.
available() Should return True (the default) if the Action is available. The Action should examine the current state in this method and assert (with an optional error message) that conditions are good for execution.
execute(path=None) Called to execute the Action. UI Actions should be undoable. Importer/Exporter actions are passed the path to the file to operate on.
