    Slot

    详细描述

    PySide adopt PyQt's new signal and slot syntax as-is. The PySide implementation is functionally compatible with the PyQt 4.5 one, with the exceptions listed bellow.

    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:

    QtCore pyqtSignal Signal
    QtCore pyqtSlot Slot

    Q_INVOKABLE

    PySide doesn't offer something identical to Q_INVOKABLE macro of Qt, the reason is simple, PySide slots can have return values, so if you need to create a invokable method that returns some value, declare it as a slot, e.g.:

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