Registry

class glue.config.Registry

Bases: object

Container to hold groups of objects or settings.

Registry instances are used by Glue to track objects used for various tasks like data linking, widget creation, etc. They have the following properties:

• A members property, which lists each item in the registry

• A default_members function, which can be overridden to lazily initialize the members list

• A call interface, allowing the instance to be used as a decorator for users to add new items to the registry in their config files
