Delayed Text box Output

If this is FAQ - someone please point me in the right direction.

I have a PerlQT application that is the front end for a process that takes 5 
or so minutes to run. That process is written as a Perl package that I call 
from my PerlQT application.  I need the process to be able to log status to a 
text box in the PerlQT application.  

I added a text box, and a couple of routines to write to the text box and 
passed the write routine to the Perl package.   It all runs fine - except 
that all the output to the text box appears at the end of the process run - 
instead of in real time as it happens.

Any ideas?

Thanks,
