Label update

high folks,
I've written a perl tk script which automatically sucks webpages
from the net and saves them on the users hard disk.
now I want to implement a lable by which the user is informed about
the progress of the download process, e.g. 'page 7 download ok.'
but obviously perl is so busy with the download process, that the
label can't be updated. only the last message after the end of the
download is displayed. I guess there will be the same problem with
the scale widget.
any suggesions?

thanx for your help, Helmut

Can you put a $toplevel->update; anywhere in your download loop?

The question becomes, "What if I'm using LWP, and I have no place at which
to insert an update call?"  I've often wondered that.

Might not apply to his situation, but I wonder all the same.

LWP::UserAgent allows you to specify a callback that will be called for
each "chunk" of data retrieved, with the "chunk" size being specified by
you.  You can call update() for each chunk.

Thanks!  Didn't know about it, but it's been a while since I was deep in
the guts of LWP.  Saved for future reference, as well as (hopefully)
committed to memory.

Apprecite it!
