- changed¶
Declares a signal emitter on a class.
This is class implements the [descriptor protocol](https://docs.python.org/3/howto/descriptor.html#descriptorhowto) and is designed to be used as a class attribute, with the supported signature types provided in the contructor:
```python from psygnal import Signal
- class MyEmitter:
changed = Signal(int)
- def receiver(arg: int):
print("new value:", arg)
emitter = MyEmitter() emitter.changed.connect(receiver) emitter.changed.emit(1) # prints 'new value: 1' ```
!!! note
in the example above, MyEmitter.changed is an instance of Signal, and emitter.changed is an instance of SignalInstance. See the documentation on [SignalInstance][psygnal.SignalInstance] for details on how to connect to and/or emit a signal on an instance of an object that has a Signal.
- Parameters
*types (Union[Type[Any], Signature]) -- A sequence of individual types, or a single [inspect.Signature][] object.
description (str) -- Optional descriptive text for the signal. (not used internally).
name (Optional[str]) -- Optional name of the signal. If it is not specified then the name of the class attribute that is bound to the signal will be used. default None
check_nargs_on_connect (bool) -- Whether to check the number of positional args against signature when connecting a new callback. This can also be provided at connection time using .connect(..., check_nargs=True). By default, True.
check_types_on_connect (bool) -- Whether to check the callback parameter types against signature when connecting a new callback. This can also be provided at connection time using .connect(..., check_types=True). By default, False.
- magicclass.ext.vispy.camera.quaternion2euler(quaternion, degrees=False) tuple[float, float, float] [source]¶
Converts VisPy quaternion into euler angle representation.
Euler angles have degeneracies, so the output might different from the Euler angles that might have been used to generate the input quaternion.
Euler angles representation also has a singularity near pitch = Pi/2 ; to avoid this, we set to Pi/2 pitch angles that are closer than the chosen epsilon from it.
- Parameters
quaternion (vispy.util.Quaternion) -- Quaternion for conversion.
degrees (bool) -- If output is returned in degrees or radians.
- Returns
angles -- Euler angles in (rx, ry, rz) order.
- Return type
3-tuple
