I'm adding things to the Windows RGui so that there's more control of the interface from within R.
One thing I'm considering is giving access to the Graphapp window objects using external pointers. This raises the issue of finalization on both sides: - If someone creates a pointer referring to a window, then that pointer should be changed to NULL when the window is closed. - If garbage collection destroys a pointer referring to a window, then the window should know not to change that pointer to NULL later. Are there other examples like this I can look at? I'd like to follow existing conventions rather than invent my own. And a related question: is there a writeup anywhere on the R_RegisterFinalizerEx function? What does the onexit argument do?
