Yes, fair enough.  :-)   However I think what surprises me here is that so
far as I can recall ROX-Lib installed without any problems. Yet IIUC CLib
seems to require even users of developed apps that use it to install a
'development' item (pkg-config) which seems absent from a distro as common
as Xubuntu.

Anyway, thinking about this I feel I do prefer (if it is possible and I can
work out how to do it) to use the approach of using python (and ROX-Lib) to
provide the drag-and-drop, and have it then call the object I've compiled
from 'C'. 

One reason for this is I want the main code to be easily accessible by
non-ROX users via a terminal or just issuing the usual sort of <object>
<variable> command.

Another is that I've played with the python example at
http://roscidus.com/desktop/Tutorials/Saving

and it works quite nicely for A and B above. So I'm hoping that there is a
simple way to extract the full pathname of the file created by the
drag-and-drop and then pass that on to launching the main code. Is there
not a method for reading this name from the class of object for 'box'. etc?

Either way I clearly have a lot to learn! So me feeling of preferring
python here may well be a mistake on my part. But I am tending to feel I
should learn more about python anyway, so that is another reason for seeing
if that route is possible. 

So if anyone can advise on how to extract the pathname of the saved file
from the SaveBox (as above example) and then how to issue the command, I'd
welcome the help. In the meantime I'll keep experimenting and trying to
learn.

Thanks,

Jim
