pyqt_reactive.widgets.shared.manager_item_hooks

Typed list-item hook declarations for manager widgets.

Classes

`AttributeItemIdProjection`(path)	Project an item id from an object attribute path.
`DictItemIdProjection`(key)	Project an item id from a mapping key.
`ItemIdProjection`()	Projects a stable selection id from a manager backing item.
`ListItemDataProjection`(project, resolve_data)	Bidirectional codec for QListWidgetItem.UserRole payloads.
`ManagerItemHooks`(id_projection, ...)	Typed source for list-item behavior consumed by AbstractManagerWidget.
