uses InterfaceBase, LCLPlatformDef;
widV:='Linked with '+LCLPlatformDisplayNames[WidgetSet.LCLPlatform]+'widget
set';
OK, Thanks. So I can see how I can derive the names etc. from that, it
appears to have been supported since the dawn of time, and linking to it
is still going to be no more intrusive than some of the other stuff
that's already in my diagnostic unit.
But out of curiosity, I'd still be very interested to know how the
compile-time definitions like the ones in my example are generated :-)
