napari.utils.events.EventedDictNamespace

class napari.utils.events.EventedDictNamespace(data: Mapping[_K, _T] | None = None, basetype: type[_T] | Sequence[type[_T]] = ())

Bases: EventedDict[str, _T]

An evented dict that also exposes its elements as a simple namespace.

Needs keys to be str.

Methods

clear()
copy()	Return a shallow copy of the dictionary.
first_callback_connect()	When the first callback is connected to self.events, connect to all child emitters.
get(k[,d])
items()
key(value)	Return first instance of value.
keys()
last_callback_disconnect()	When the last callback is disconnected from self.events, disconnect from all child emitters.
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised.
popitem()	as a 2-tuple; but raise KeyError if D is empty.
setdefault(k[,d])
update([E, ]**F)	If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
values()

Attributes

Details

clear() → None.  Remove all items from D.

copy() → TypedMutableMapping[_K, _T]

Return a shallow copy of the dictionary.

first_callback_connect() → None

When the first callback is connected to self.events, connect to all child emitters.

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.

items() → a set-like object providing a view on D's items

key(value: _T) → _K | None

Return first instance of value.

keys() → a set-like object providing a view on D's keys

last_callback_disconnect() → None

When the last callback is disconnected from self.events, disconnect from all child emitters.

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised.

popitem() → (k, v), remove and return some (key, value) pair

as a 2-tuple; but raise KeyError if D is empty.

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D

update([E, ]**F) → None.  Update D from mapping/iterable E and F.

If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

values() → an object providing a view on D's values
