Editing a parameter while creating a sub-class?

[Steve555]

Hi,

I'm creating an object CSub, which is sub-classed from CMaster.

The constructor for either takes a struct as an argument:

CSub:: CSub(BasicModel *inModel : CMaster(inModel)

and this is the struct:

typedef struct{
long size;
long numVertices;
long numTris;
}BasicModel;


What I want to do is edit some inModel parameters for creating a
CSub, before passing it on to the CMaster constructor.

Is there a way to do this?

Thanks

Steve

Yes, it did, thanks. Though after reading how they did it, it occured
to me it I could also just create a wrapper function to create the sub-
class, after first editing the parameter.
