Description Lauro Moura 2010-04-08 15:02:17 EEST

Trying to connect a functools.partial to a signal gives "Invalid callback
object" message. The same happens to objects with __call__ methods.

Comment 1 Hugo Parente Lima 2010-04-08 15:36:04 EEST

Sample code from Stuart McNicholas:

from PySide import QtCore
import functools

def aslot(args=None):
  print "slot",args

app = QtCore.QCoreApplication([])

o = QtCore.QObject()

o.connect(o,QtCore.SIGNAL("ASignal"),functools.partial(aslot,"partial .."))
o.emit(QtCore.SIGNAL("ASignal"))
