I have the following code (copied from a post in 2009) <c> #!/usr/bin/perl -- use strict; use warnings; use Tk; my $mw = tkinit(); my $l = $mw->Scrolled(qw' Text -height 2'); $mw->Button( -text => 'add', -command => sub { $l->insert( 'end', localtime() . "\n" ); $l->see('end'); } )->pack; $l->pack; $l->insert( 'end', "hi\nthere\n" ); MainLoop();

...which works fine as a demo - but I need to add to the scolling box more or less infinitely (long running app logging diags to the scroll area) - presumably this will slowly use more and more memory as text lines are added...

is there some way to have the scrolling box as a sort of FIFO with just a few hundred lines in the "history" ?

thanks
dave
