print rsync output real-time to GUI in perl::gtk2

[Gooberlx2]

I'm writing a simple little perl gui for a specific rsync command.

I want to capture and print the output from that rsync to a status textarea.

The hitch is that the text area won't print the output until the command has finished, whereas a simple print command shows I am properly capturing and printing the information in real-time.

Any ideas?

my $pid = open(OUT, "$cmd |") || die "failed: $!\n";
my $out;
while(read(OUT, $out,1)==1 ){
print $out;
$textbuffer->insert($textbuffer->get_end_iter, $out);
}

edit:
Well, I just wrote something in Java instead. I'm not sure why it wouldn't update the textarea when the the print command worked just fine. Could have been a threading issue, but I'm not familiar with working with threads in perl.

Do you have to flush/refresh the textarea after each insert?

I dunno, but I don't see any such methods for either textbuffer or textview in the API.
