Whoops! Sorry, had those in there because they are a
whole lot more useful than the real error handlers
during debugging. Gone now. :-)

No, they are easy. The only difficulty is knowing
how to write them without common blocks. But you have
my book, so I'm *certain* you know how to do that! :-)
Cheers,
David
P.S. The biggest mistake most people make when starting
out to write compound widgets is to use the programs
supplied with IDL as examples. *Those* will get you
lost, for sure. :^)

Hi David and all,
I just tried DWF's program. I did not have the program,
error_message.pro , so the compilation failed. However, getting it
from DWF's web page, everything worked fine.
I gave up on making compound widgets last year. It would be
interesting if using objects would simplify this procedure, as I found
it difficult.
