[vtkusers] C++ to Python convertion?

[kent williams]

Um, I think you need to look at the PYTHON code examples in the
KWWidgets widget tour program.  I don't use Python so I don't know the
equivalent operation, but SafeDownCast is a specific C++ thing -- the
'caller' in this case is a parameter to the callback function, and has
a generic KWWidgets * type; the SafeDownCast is just a 'safer' version
of

loadSaveDialog = (vtkKWLoadSaveDialog *)caller;

in other words, the caller has the superclass type (e.g. vtkKWWidget)
and you need to treat it like a particular type (vtkKWLoadSaveDialog).
