Hi MONKS

i would like to include ok and cancel button in my script, once the ok is clicked selected file have to be stored in a seperate file (C:\\waste\\data.txt) and the interface have to be closed

#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::Pane;

my $topdir="C:\\windows";
#my $topdir= shift || "$topdir";
my @subdirs = get_sub_dirs($topdir);

my $mw = tkinit();
$mw->geometry('200x400+200+200');

my $sp = $mw->Scrolled('Pane', -scrollbars=>'osoe', sticky=>'nwse')
     ->pack(-expand=>1, -fill=>'both' );

my @cbvalues;
my @cbnames;
my $count = 0;
foreach my $d( @subdirs){

  $cbnames[$count] = $d;

  $sp->Checkbutton(-text => $d,
        -font=>[arial => 12],
        -onvalue => 1,
        -offvalue => 0,
        -variable => \$cbvalues[$count],
        -font => 'small',
        -bg => 'White',
     )->pack(-anchor=>'w')->pack();

$count++;
}

my $showbutton= $mw->Button(-text=>'OK',
-bg => 'green',
-command => sub{
       my @selected = ();
       foreach my $c( 0.. $count ){
            if ( $cbvalues[$c] ){
                push @selected, $cbnames[$c];
              }
         }

      open (MYFILE, '>>C:\\waste\\data.txt');
 print MYFILE "@selected\n";
 close (MYFILE);


      #print "@selected\n";
      } )->pack();

MainLoop();


sub get_sub_dirs {
 my ($dir) = @_;
 opendir my $dh, $dir or die "Error: $!";
 my @files = grep !/^\.\.?$/, readdir $dh;
 closedir $dh;
 my @sdirs;

 for my $file ( @files ) {
   if(!-f $file){push @sdirs,$file;}
  }

return @sdirs;
}

Re: adding button and exit

    In your subroutine, get_sub_dirs, you were missing this line: 
    @files = map { decode( 'utf8', "$dir/".$_ ) } sort @files;

    Now for your cancel button: 
    
my $showbutton2 = $mw->Button(
    -text => 'Cancel',
    -bg   => 'red',
    -command => sub {exit} )->pack;

MainLoop();

    Here's the complete script: 
    #!/usr/bin/perl

use strict;
use warnings;
use Tk;
use Tk::Pane;
use Encode;

my $topdir = '/root/Desktop';
my(@subdirs) = get_sub_dirs($topdir);

my $mw = tkinit();
$mw->geometry('200x400+200+200');

my $sp = $mw->Scrolled('Pane', 
    -scrollbars => 'osoe', 
    -sticky => 'nwse')->pack(
    -expand=>1, 
    -fill=>'both' 
);

my @cbvalues;
my @cbnames;
my $count = 0;
foreach my $d( @subdirs){
    $cbnames[$count] = $d;
    $sp->Checkbutton(-text => $d,
         -font=>[arial => 12],
         -onvalue => 1,
         -offvalue => 0,
         -variable => \$cbvalues[$count],
         -font => 'small',
         -bg => 'White',
     )->pack(-anchor=>'w')->pack();

$count++;
}

my $showbutton1 = $mw->Button(
    -text => 'OK',
    -bg   => 'green',
    -command => sub {
        my @selected = ();
        foreach my $c( 0.. $count ){
            if ( $cbvalues[$c] ){
                push @selected, $cbnames[$c];
        }
}

open (MYFILE, '>>', '/root/Desktop/System.pm');
print MYFILE "@selected\n";
close (MYFILE);
print "@selected\n";
})->pack();

my $showbutton2 = $mw->Button(
    -text => 'Cancel',
    -bg   => 'red',
    -command => sub {exit} )->pack;

MainLoop();


sub get_sub_dirs {
    my ($dir) = @_;
    opendir my $dh, $dir or die "Error: $!";
 
    my @files = grep !/^\.\.?$/, readdir $dh;
    closedir $dh;
    @files = map { decode( 'utf8', "$dir/".$_ ) } sort @files;
 
    my @sdirs;
    for my $file ( @files ) {
    if(!-f $file){push @sdirs,$file;}
    }
    return @sdirs;
