object toolkit

I don't understand your question. Do you want to push sequences of doubles inside a ProArray structure?

It didn't make sense ... so you could create a sequence for that (don't know what you want):

//not tested : )

double d = 2.0;

xdoublesequence_ptr xds = xdoublesequence::create();

xds.append(d);

It's a shared_pointer so don't delete or free it ^.^
