The code:


class File (QDeclarativeItem):
    def __init__(self, parent = None):
        QDeclarativeItem.__init__(self, parent)
        self._name = ""

    nameChanged = Signal()

    def getName(self):
        return self._name

    def setName(self, value):
        if value != self._name:
            self._name = value
            self.nameChanged.emit()

    name = Property(getName, setName, notify = nameChanged)

doesn't throw any exception, but if you try:

f = File()
print f.name

# you get
TypeError: setName() takes exactly 2 arguments (1 given)
