[vtk-developers] Python wrapped void pointers

A project I work on is facing a regression related to the
vtkRenderWindow::SetDisplayId(void*) method.

It apparently used to work by passing a string similar to:

'_f02100_void_p'

as the argument, but now they're getting TypeErrors:

TypeError('SetDisplayId argument 1: value is _f02100_void_p, required type
is p_void',)

For context, the failure is happening here:

https://github.com/UV-CDAT/VisTrails/blob/cb2220ba88e957006c3dcc098ef29c5c08461117/vistrails/packages/vtk/vtkcell.py#L356

It looks like the python wrappers might have changed how they handle the
void* type -- does anyone have an idea what's going on here?

Thanks,
Dave
