I don't really know what the problem you're having is but this code is very difficult to read. What's the point of the _fromUTF8 function? The strings you pass it are all ASCII, so if you're trying to create unicode strings you could just use the u prefix e.g. u"toggled(bool)". Also you can avoid referring to the same deeply nested attributes by importing them or assigning them to something first e.g.: from QtCore import SIGNAL from QtCore.QObject import connect # Not sure if QObject is a module... ## Checkbox: setfilter = self.materialsInstance.setFilterDict connect(self.checkBox, SIGNAL(u"toggled(bool)"), lambda: setfilter("C", self, "name", self.lineEdit.text())) Oscar -- https://mail.python.org/mailman/listinfo/python-list
