[Maya-Python] How to us Custom MPxData from cpp in python.

[Cameron Fulton]

Hi all,

So I have a custom data type that I create in cpp that I use for an 
attribute on a custom node. My custom data type is pretty straight forward:
class BlindData : public MPxData
{


 public:
    BlindData();
    virtual ~BlindData();


  /**
   * Copy the local data from a similar data object
   *
   * @param MPxData
   *   Data object to copy from.
   */
  virtual void copy(const MPxData&);


  MStatus
  readBinary(istream& in, unsigned int length);


  MStatus
  writeBinary(ostream& out);


  MTypeId typeId() const;


  MString name() const;

  static MString typeName;
  static MTypeId id;
  static void* creator();


  std::vector<char> m_data;
};

And then I just use that as a type for my attr on my node
  MFnTypedAttribute tAttr;
  MStatus stat;

    blindDataAttr = tAttr.create("blindData",
                                 "blind",
                                 BlindData::id,
                                 MObject::kNullObj,
                                 &stat);
   addAttribute(mPoseDataList);


So now I want to set that in Python, but I'm not sure how too. Anyone run 
into this before?
