Hello!

I am using perk/tk here and am having issues creating a file menu and having it perform a specific action based on a directory search.

----------

So previously I had the commands hard-coded and it looked like this: 

 $menubar = $top->Menu;
   $file_menu = $menubar->cascade(-label => "~File");
   $file_menu->command(-label => "Restart", -command => \&Restart);
   $file_menu->command(-label => "Exit", -command => \&Exit);

   $file_menu = $menubar->cascade(-label => "Filter");

   $file_menu->command(-label => "All", -command => sub {$fname = "mac
+hines"; &Restart});
   $file_menu->command(-label => "HP-UX", -command => sub {$fname = "m
+achines.HPUX"; &Restart});
   $file_menu->command(-label => "Linux", -command => sub {$fname = "m
+achines.Linux"; &Restart});

But have since decided to pull the list (HP-UX, Linux, other things in the future), from files found in a directory. So now my code looks like this:

# Get filter list
   my @filter = qw();
   my $dir = '.';
   my $x=0;
   opendir(DIR, $dir) or die $!;
   while (my $file = readdir(DIR)) {
     next unless (-f "$dir/$file");
     next unless ($file =~ m/^machines\./);
     push (@filter, $file);
   }
   closedir(DIR);

   $file_menu = $menubar->cascade(-label => "~File");
   $file_menu->command(-label => "Restart", -command => \&Restart);
   $file_menu->command(-label => "Exit", -command => \&Exit);

   $file_menu = $menubar->cascade(-label => "Filter");
   $file_menu->command(-label => "All", -command => sub {$fname = "mac
+hines"; &Restart});

   foreach (@filter) {
     $file_menu->command(-label => "$_", -command => sub {$fname = "$_
+"; &Restart});
}

------------------

However the issues lies in that when the button is clicked, "$fname" no longer knows what "$_" is, or is null.

So my question is, how can I create a file menu based on an array but still be able to set a variable in the command portion of the menu command?

I hope that all makes sense!
