args is a tuple containing the options passed to Button.__init__ QPushButton
does not take a tuple as its arguments I suspect

>               apply(QPushButton.__init__,(self,)+args)  ...2

passes a tuple (self, args) to QPushButton.__init__ via apply which turns the
arg tuple into the arguments QPushButton is expecting.  In python 2.1 and newer
you can call 

QPushButton.__init__(self, *args) # pass argument tuple through to function.

In 1.x you have only apply() to use.
