When you use setStyle, which types of Widgets will it affect? It seems to do nothing with a bare QLabel widget, as I documented here (and which I thought was an error):
http://stackoverflow.com/questions/2...in-pyside-pyqt

Is there documentation on this somewhere, or is this something I should just find by trial and error?

And is this the best-practices way to change style in PySide?
Qt Code: 
  1. QtGui.QApplication.setStyle(QtGui.QStyleFactory.create('Cleanlooks'))
To copy to clipboard, switch view to plain text mode
