This is surely something stupid... but I have no good ideas tonight. I want to a) create a Tk (main) window, b) after the window has been displayed, call a subroutine, c) when the subroutine has been performed, destroy the window. In my script, Tk is correctly expecting an event to call the subrutine. Which is the best method to automate this?

use strict;
use warnings;
use Tk;

my $mw = MainWindow->new();
$mw->Label(
    -text => "Wait",
    -font => [-family => 'times', -size => 20],
)->pack(-expand => '1', -fill => 'both');
$mw->MainLoop;

doSomething($mw);#this is doing nothing here, it should be automatical
+ly called after creation and display of mainwindow

sub doSomething{
my $mw = shift;
print "Hello!\n";
$mw->destroy;
}
