jdxi_editor.ui.widgets.controls.registry

Control Registry

Dict-like registry of parameter -> widget, owned by SynthBase (or one per partial). Supports get(param) with optional name fallback so param identity matches across partials. Use register(param, widget) or registry[param] = widget; lookup via registry.get(param) or registry[param].

Classes

ControlResolver	Base class for protocol classes.
ControlRegistry	Registry of parameter -> control widget. Dict-like; singleton instance shared across all partials.

Bases: Protocol

Base class for protocol classes.

Protocol classes are defined as:

class Proto(Protocol):
    def meth(self) -> int:
        ...

Such classes are primarily used with static type checkers that recognize structural subtyping (static duck-typing), for example:

class C:
    def meth(self) -> int:
        return 0

def func(x: Proto) -> int:
    return x.meth()

func(C())  # Passes static type check

See PEP 544 for details. Protocol classes decorated with @typing.runtime_checkable act as simple-minded runtime protocols that check only the presence of given attributes, ignoring their type signatures. Protocol classes can be generic, they are defined as:

class GenProto(Protocol[T]):
    def meth(self) -> T:
        ...
