The problem is that while testing to see if it's OK to save the user's
data,
the program discovers a minor problem.

In the "curses" version of the program, it is simple to ask the user if
he wants
to ignore the minor problem and save the data anyway.  This is done
without
disrupting the flow of the program...

if ( Confirm ( "Hey buddy, are you sure? (Y/N)" ))
{
  ... do other processing and testing and perhaps more confirming...
  ...
  Write the data to disk;

Quote:}

else
  return;

I can see only one ugly way to do this in GTK.  That is to create call a
new
program that will ask the question and return a value.  It is trivial to
block
execution of the main program while the child program is waiting for a
reply.

I have looked at the GIMP source code to see how it does this sort of
thing.
But I don't see how its solution will work for me.

(So, it looks like I'm writing a program just to do Confirmation Windows
until
such time as I can learn of a better idea).

Simple hint: The gtk_main() function (um, at least I think that's
what it's called) is "reentrant". You can create a modal requester
asking for the confirmation, and then call gtk_main() to run it.
As the requester closes, call gtk_main_quit() (again, I'm not sure
that's the actual function name, look it up) to "back out" of the
nested GTK+ loops. For an example of how this is done, grab gentoo
from <ftp://ftp.obsession.se/gentoo/gentoo-0.9.23.tar.gz>. :)
