[PyKDE] Using SIP to call Python from C++

[Niac Neb]

Jim,

You are helping me greatly!!!

I know how to **call** a C++ object from Python ...
just not how to **pass** the object from C++ to
Python.

So, how would I pass the following C++ object,
cPlotData, to Python?

struct sVec2
{
   int x;
   int y;
};

class cPlotData
{
public:
   int GetSize() { return mData.size(); }
   sVec2 Get(int i) { return mData.at(i); }
protected:
   std::deque< sVec2 > mData;
};

How should I pass an instance of this using Python/C
API?

I'm assuming you are referring to using these:
  PyObject_CallObject
  PyDict_GetItemString
  PyTuple_SetItem
Or, is there an easier way?
