self.tableWidget.cellChanged is a pyqtBoundSignal object.

signals can have several different signatures. so pyqtBoundSignal 
objects define __getitem__ to allow the different signatures to be 
accessed by key like a dict.

in this case, the key is the tuple: (int, int). so your code should be:

self.tableWidget.cellChanged[(int, int)].connect(self.tableWasModified)

or, more cleanly:

self.tableWidget.cellChanged[int, int].connect(self.tableWasModified)

also note that if the signature is omitted, a default signature will be 
used instead. so in this case you could get the same result by using:


(which i believe was suggested earlier in this thread).
