Then look at the docs. There's a big fat Warning that using sender violates OO-principles and the signal/slot mechanim. There are quite some restrictions on sender() which you always have to have in the back of you head. > Still trying to get a simple QSignalMapper example to run. In the PyQt4 > examples it is used only in mdi.py which isn't exactly simple, right? Actually I think it is a simple example, you do look at the python version do you? I guess best idea would be to strip it down to only include the open and the open-recent-files stuff and remove everything else. That should make it as simple as it can get.
