Detailed Description
--------------------
The :class:`~.Signal` class provides a way to declare and connect Qt
signals in a pythonic way.
.. class:: PySide6.QtCore.Signal([type1 [, type2...]] [, name="" [, arguments=[]]])
:param name: str
:param arguments: list
``Signal`` takes a list of Python types of the arguments.
It is possible to use the same signal name with different types by
passing a list of tuples representing the signatures, but this is a legacy
technique recommended against in new code (see
:ref:`overloading-signals-and-slots`).
The optional named argument ``name`` defines the signal name. If nothing is
passed, the new signal will have the same name as the variable that it is
being assigned to.
The optional named argument ``arguments`` receives a list of strings
denoting the argument names. This is useful for QML applications which
may refer to the emitted values by name.
.. method:: Signal.connect(receiver[, type=Qt.AutoConnection])
Create a connection between this signal and a `receiver`, the `receiver`
can be a Python callable, a :class:`Slot` or a :class:`Signal`.
.. method:: Signal.disconnect(receiver)
Disconnect this signal from a `receiver`, the `receiver` can be a Python
callable, a :class:`Slot` or a :class:`Signal`.
.. method:: Signal.emit(*args)
`args` is the arguments to pass to any connected slots, if any.
