I don't think the template class route allows for a reliable way to get the exact object size. Remember the size i am talking about is also determined by state i.e. the contents of variable size members. _______________________________________________ *Good judgement comes from Experience.* *Most of that comes from Bad Judgement.* _______________________________________________ * * 2011/11/28 Steve Obbayi <steve@sobbayi.com>
Have you considered implementing your class as a template class that way you can handle all the specific data types you want to D&D at runtime and get a more accurate value to allocate to memory using the sizeof() operator.
You might not know the type of the data being D&D so you might want to add the following header
#include <typeinfo.h>
to get the actually type of the data then call
typeid(theObject).name();
I have not actually used this but i vague remember it being handy in such a case. corrections welcome.
Or you could if else through all supported types and check for a not null with a dynamic cast then apply the sizeof on the successful cast

I'm using wxWidgets. It's clipboard mechanism extends the underlying platform's clipboard mechanism.
The object is of a custom class. This class contains various datatypes ranging from ints,doubles,std::strings,char pointers to custom typedefs, structs and other classes.
The objects i want to D&D are of different types. I will have a clipboard data object for each type as opposed to having an abstract implementation which is more complex.
