Slot

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:

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)
