Hi everyone,
I'm experimenting with PyQt4 signals. According to the documentation,
any Python callable can be used as a slot. However, I can't get
closures to work as I would expect them to. Here's some sample code
that exercises the situation:
from PyQt4 import QtCore
#!/usr/bin/env python
class A(QtCore.QObject):
def __init__(self):
QtCore.QObject.__init__(self)
def makeClosure(self, x):
def f():
print x
return f
a = A()
a.connect(a, QtCore.SIGNAL("testClosure"), a.makeClosure(5))
a.makeClosure(6)()
a.emit(QtCore.SIGNAL("testClosure"))
Executing this only prints "6" to stdout on my Intel MacBook running
PyQt4.
PyQt4 version: mac-gpl-snapshot-20060604
sip version: sip-snapshot-20060525
Qt version: 4.1.3
Is this a known issue? If any more info is needed to reproduce this,
let me know.
Thank you very much in advance,
-carlos
