[Rcpp-devel] c++ graphics device

[Romain Francois]

Hello,

R's graphics device drivers are currently written using poor man's c++: 
you are supposed to create a pDevDesc struct (defined in 
R_ext/GraphicsDevice.h) and then fill it with function pointers, e.g 
(from the NULL device) :

     /*
      * Device functions
      */
     dev->close = NULL_Close;
     dev->activate = NULL_Activate;
     dev->deactivate = NULL_Deactivate;
     dev->size = NULL_Size;

I'd like (not now, but sometime) to encapsulate this into C++ so that 
writing a device would more naturally be done by deriving some class 
rather than the pseudo c++ done in C implementation.

I believe this could help people implement other graphics devices using 
c++ idioms.


Should this go into Rcpp (I think I prefer this option) or should it be 
some other package (RcppGD, or something).

Romain
