Hello,everyone:

<<How to be in the following code rolling display data (real time)? 

use Tk;

my $mw = new MainWindow; # Main Window
my $frm_name = $mw -> Frame();
my $lab = $frm_name -> Label(-text=>"IP:");
my $ent = $frm_name -> Entry();
my $but = $mw -> Button(-text=>"Push Me", -command =>\&push_button);
my $textarea = $mw -> Frame(); #Creating Another Frame
my $txt = $textarea -> Text(-width=>40, -height=>10);
my $srl_y = $textarea -> Scrollbar(-orient=>'v',-command=>[yview => $t
+xt]);
my $srl_x = $textarea -> Scrollbar(-orient=>'h',-command=>[xview => $t
+xt]);
$txt -> configure(-yscrollcommand=>['set', $srl_y],
-xscrollcommand=>['set',$srl_x]);
$lab -> grid(-row=>1,-column=>1);
$ent -> grid(-row=>1,-column=>2);
$frm_name -> grid(-row=>1,-column=>1,-columnspan=>2);
$but -> grid(-row=>4,-column=>1,-columnspan=>2);
$txt -> grid(-row=>1,-column=>1);
$srl_y -> grid(-row=>1,-column=>2,-sticky=>"ns");
$srl_x -> grid(-row=>2,-column=>1,-sticky=>"ew");
$textarea -> grid(-row=>5,-column=>1,-columnspan=>2);
MainLoop;
#This function will be executed when the button is pushed

sub push_button {
  my $ip = $ent -> get();
  my $ping = `ping $ip`;

$txt -> insert('end', "$ping");#Here is not the results of real-time d
+isplay

}

Here to run the results without scrolling display, how to modify?

Thanks!
