Yeah, anyway I checked again and even original Anita's statement worked for me. This is what I did in python console: from PyQt4.QtCore import * class A(QObject): def __init__(self): QObject.__init__(self) def f(self, painter): import sys; sys.__stdout__.write("hello\n") a = A() iface.mapCanvas().renderComplete.connect(a.f) when moving the map, it will output "hello" to the system console from where I started QGIS... so problem is probably somewhere else, not with connection itself. > Apropos does either connect actually return True? I have learned not to trust the return value of connect() at all, for example: >>> QObject.connect(iface.mapCanvas(), SIGNAL("abracadabra()"), a.f) True I'm pretty sure map canvas cannot do this kind of magic!
