My program has a loop like so

while ( doSomething() ) ;

doSomething does some calculations and may change the display, but I 
can't see the changes until the loop exits.  I would like the display to 
be updated on each iteration.

I've tried

while ( doSomething() )
   Fl::flush();

but this still doesn't do what I'd like.

Is there a way to do what I'm looking for?

I'm using the latest 1.3.x on Linux.

Mike
