Overload MPxNode::legalConnection in Python

[Anonymous]

Hi,

I've got a scripted plug-in with a custom node. I need to overload MPxNode::legalConnection(), but I am not sure how to set the value of the boolean isLegal parameter to indicate whether or not the connection is valid. It looks to be some kind of SWIG wrapped pointer value

Any help would be greatly appreciated!

Okay...a little searching the answer lies in the ctypes module:

import ctypes

def legalConnection(self, plug, otherPlug, asSrc, legal):
    pLegal = ctypes.cast(legal.__long__(), ctypes.POINTER(ctypes.c_bool))
    pLegal = False
