Yes, Alex, that does the job!  In fact, it works if I add the stretch=0 
argument just to the first button ("one"). I didn't think of 
manipulating the stretch, because I wanted to *move* the button, not 
change its size. I guess I'll need to understand better the interaction 
between specifying QSizePolicy.Fixed and a 0-sized stretch:

   "If the stretch factor is 0 and nothing else in the QBoxLayout has a 
stretch
    factor greater than zero, the space is distributed according to the
    QWidget:sizePolicy() of each widget that's involved."

Many thanks,
John
