Convert PyQt properties to Python properties (Python recipe) by Miguel Turner
ActiveState Code (http://code.activestate.com/recipes/577539/)

This recipe will find all attributes created as meta-object properties in Qt and will create a Python property of the same name for each of them. This is a quick way of providing some of the functionality suggested by PSEP 102, which I sincerely hope will be accepted, as it will make PySide considerably more pythonic.

@useProperties
class Widget(QtGui.QWidget):
    pass

# or simply
useProperties(QtGui.QWidget)

# then
w = QtGui.QWidget()
w.font = QtGui.QFont('Droid Sans Mono')

Note that this will not replace any getters/setters for attributes that are not declared as properties, such as QWidget.setParent.
