[PySide] PySide calls wrong emit() inside class

[Robert Schilling]

Hi Nathan,

Thanks for the answer, but this doesn't work either:

from PySide import QtCore
from PySide.QtCore import QObject

class Foo(QObject):
    def __init__(self):
        QObject.__init__(self)
        self.sig = QtCore.Signal(str)

    def emit(self):
        self.sig.emit("1")

x = Foo()
x.emit()

This triggers the following error:
    self.sig.emit("1")
AttributeError: 'PySide.QtCore.Signal' object has no attribute 'emit'

Having the classwide signal, this is from the type ySide.QtCore.Signalnstance.

Hi Robert,
You've created your signal at the class level, so it is shared by all instances of Foo. What you want is the signal at the object level, so each instance holds its own signal. Do so by creating the signal in the __init__ method.
def __init__(self):
   QObject.__init__(self)
   self.sig = QtCore.signal(str)

Consider following example:

class Foo(QObject):

    sig = QtCore.Signal(str)

    def __init__(self):
        QObject.__init__(self)

    def emit(self):
        self.sig.emit("1")

x = Foo()
x.emit()

This example doesn't work. When calling self.sig.emit("1") actually Foo.emit() is invoked.
Testing this example works with PyQt (that's what I'm migrating from).

Am I doing something wrong? How can I avoid this?
