Sure thing. When you get the vector back, I'll assume (for the moment) that you can iterate through the vector and get the ParticleAnalysisReport objects back...
Code:
ParticleAnalysisReport& par = (*vPAR)[i];
int h = par.boundingRect.Height;
I am doing this a bit from memory earlier today - but basically there is a "Rect" structure which is what boundingRect is within the Report class. It has Top/Left/Width/Height.
That's the ticket.
