RegistriesModel

class omni.kit.window.extensions.exts_properties_registries.RegistriesModel

Bases: AbstractItemModel

A model representing a collection of registry items for an application.

This class maintains a list of registry items, each represented by a `RegistryItem` instance. It provides methods to load registry data, add or remove registry items, save changes, and set a default registry.

The class uses an internal model to manage the state of each registry item and to interact with the UI for displaying and editing registries. It also handles notifications for registry changes and ensures that registry updates are saved to the application settings.

The model is used in conjunction with a UI tree view to enable users to view and modify the list of registries in a structured fashion.

add_empty()	Adds a new empty item to the model.
