Qt Slots

Detailed Description

PySide6 adopt PyQt’s new signal and slot syntax as-is. The PySide6 implementation is functionally compatible with the PyQt one, with the exceptions listed below.

PyQt’s new signal and slot style utilizes method and decorator names specific to their implementation. These will be generalized according to the table below:

Module	PyQt factory function	PySide class
QtCore	pyqtSignal	Signal
QtCore	pyqtSlot	Slot

class PySide6.QtCore.Slot([type1 [, type2...]] [, name="" [, result=None, [tag=""]]])

Parameters:

• name – str

• result – type

• tag – str

Slot takes a list of Python types of the arguments.

The optional named argument name defines the slot name. If nothing is passed, the slot name will be the decorated function name.

The optional named argument result specifies the return type.

The optional named argument tag specifies a value to be returned by QMetaMethod.tag().

Q_INVOKABLE

There is no equivalent of the Q_INVOKABLE macro of Qt since PySide6 slots can actually have return values. If you need to create a invokable method that returns some value, declare it as a slot, e.g.:

class Foo(QObject):

    @Slot(float, result=int)
    def getFloatReturnInt(self, f):
        return int(f)
