Hi,

My goal is it to see a button for 1 second and then it shall disappear. The following code is NOT working. It seems that the GUI is NOT updated after the first pack command. How can I force Perl/Tk to update the GUI after the first pack command?

#!/usr/bin/perl 

use Tk;

my $mw =  new MainWindow;
my $button =  $mw->Button('-text' => 'GO')->pack;

sleep(1);

$button->packForget();

MainLoop();

Thank you very much for your help
Dirk
