Hi,

Thank you for a constructive answer.

I accept your answer without reservation - I agree that the resources in Qt 
are a bit of magic...  The ignore warning "comment" is a good solution as long 
as it applies only to the next warning.  I would not want to loose the 
warnings completely as I am fond of them!

Regards,
Al.
