[PyQt] KIntNumInput question

[Neal Becker]

        num_in = KIntNumInput (self, 0, 0, 16)
 
gives:
TypeError: too many arguments to KIntNumInput(), 1 at most expected

But according to 
http://api.kde.org/pykde-4.1-api/kdeui/KIntNumInput.html#obj175289196

There are constructors taking 1,2, and 3 args.  What am I missing?  Is there some other doc I should be looking at?
