Tk Scrolled

michaelg has asked for the wisdom of the Perl Monks concerning the following question:

Hi all ,
I'm using Tk's Scrolled in the next way:
my $text = $nw->Scrolled('Text',
The problem is the text window does not role down
automatically for every text I send .
I made a little research and found the "jump=>" option
should do the trick , but it didn't work ( I think it is a known bug) .
maybe one of U monks have a solution.

    Try this snippet:
    #!/usr/bin/perl use Tk; use strict; my $mw=tkinit; my $textarea = $mw->Scrolled("Text",-scrollbars => 'ose')->pack; $mw->after(1000,\&filltext); MainLoop; sub filltext { for (1..100){ $textarea->insert('end', "$_\n"); $textarea->see('end'); $textarea->idletasks; $mw->after(50); #this is just to slow things down } }

[hippo]: Try it and see. Your computer won't explode.
[Corion]: length will tell you the length of a string.
[Corion]: But if you are parsing CSV, again, let me point to Text::CSV_XS, which you should use instead
[hippo]: +1 for Text::CSV_XS
[ovedpo15]: Im not allowed to use additional modules, so I can't use it. looking for a simple regex to do this task though..
[Corion]: Ah, so this is homework? Then most likely, you should review your course material closer. It would greatly surprise me if the course material wouldn't mention the topics that will be used in the homework...
[Corion]: I already showed you the simple regex to match the last part of a string without a comma in it
[Tux]: Corion++ hippo++
