When creating the button, you know what frame to delete. There are two ways how to pass parameters to callbacks: you can use a closure or use an array reference:
# Closure - BROKEN!
$frame[$a] -> Button(-text => "Delete frame", -command => sub { rmv( $
+frame[$a]) })->pack;
# Array ref
$frame[$a] -> Button(-text => "Delete frame", -command => [ \&rmv, $
+frame[$a] ] )->pack;
}
sub rmv {
shift->destroy;
}
Update: Oops, closures do not work for global arrays. Fix:
for (0 .. 5) {
my $frame = $fmain->Frame(-borderwidth => 0)->pack(-side => 'left'
+);
$frame->Label( -text => "Frame " . \$whichframe[$_] )->pack;
$frame->Button(-text => "Delete frame",
-command => sub { rmv($frame) },
)->pack;
}
