Sorry, Lars, I still don't understand why you need to ask a button if it is packed. Doesn't the following do pretty much what you describe? -------------------------------------------------- #!/bin/env perl use strict; use warnings; use Tk; my $MW = MainWindow->new; new_button($MW, "First button"); MainLoop; sub new_button { my $top = shift; my $label = shift; my $b = $top->Button(-text => $label, -command => [\&new_button, $top, "Another Button"]); $b->pack; } -------------------------------------------------- HTH -- Brian Raven /* This bit of chicanery makes a unary function followed by a parenthesis into a function with one argument, highest precedence. */ -- Larry Wall in toke.c from the perl source code ----------------------------------------------------------------------- The information contained in this e-mail is confidential and solely for the intended addressee(s).
