My Perl/Tk book implied that DialogBox is a 
composite widget written in perl (it refers to 
DialogBox.pm). So I went looking on the web... 

I found a copy of the source code (I didn't want 
to download the 3 meg Perl/Tk library that 
normally contains it). You can see it by doing a 
google search for:
  "dialogbox.pm" source faqchest

It seems to be about 150 lines of code. If you 
wait long enough, at some point I'll need it for 
my own application, and will try to port it over. 
Given that I don't know perl, I'll hope that 
someone beats me to it. It doesn't look too bad, 
though.
