First you need to tell us how you really installed PyQt. If you do this through MacPorts , which I recommend, your qt4-mac port name. (You can verify it with the port list installed command.)
By default, the installation does not include demos or examples. You can enable both with:
sudo port install qt4-mac +demos +examples
This procedure is quite slow, up to several hours.
In the /opt/local/share/qt4/ you will find demos and examples , and in Applications/MacPorts/Qt4 will be qtdemo .
