Nick,
Thanks for the info. I found another way around the
problem which you might find of interest. The problem
was that the method "dragPromisedFilesOfTypes:"
method doesn't exist pre-10.2. However the base class
known as "Object" has a method "respondsToSelector:"
so you can perform a test to see if some troublesome
method actually exists, i.e.
if ( [self
respondsToSelector:@selector(dragPromisedFilesOfTypes:fromRect:source:sl
ideBack:event:)] == NO ) {
fprintf( stderr, "Promised file drag-and-drop is not supported.\n" );
return;
}
So far it has only been this matter that has caused a
problem, so this is probably the simplest way around
it for now. Thanks for the info though.
Regards,
Tim.
