You really need to show some code, but in general, windows should update themselves automatically. If your code is setup so that it dosn't update itself, there are a few things you can use:

A timer 

my $repeater =
      $mw->repeat(1000, sub{   #repeats every second (1000 ms)
                 &refreshing_sub1;
                 &refreshing_sub2;
                #etc etc
                $mw->update;   
         });

#later
$repeater->cancel;  #to stop it

But you really need to show some example code. There are all sorts of builtin Tk methods for auto-updating, ranging from fileevent callbacks, to tied textvariables for the various widgets. If you are doing something like making a socket connection, or running something like a cron job, a timer should do it.
