With that you're testing how fast a QWidget can set its internal state variables from hidden to shown. You don't test any painting performance. If you want to do that, you'll probably have to either - patch Qt - or write a subclass of QPushButton which overrides paintEvent() and then times how long a call to the base class implementation needs. And then you should do just either a hide or a show, as doing both might simply be discarded due to how the event queue works.
