(Written before you showed your code) Probably the reason is that readdir just returns the file name. If you want to do file tests on the file, you need to include the path... like so:
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
my %tk;
$tk{mw} = MainWindow->new;
$tk{frame} = $tk{mw}->Frame->pack(
-expand => 1,
-fill => 'both',
-anchor => 'nw'
);
$tk{listbox} = $tk{frame}->Scrolled(
'Listbox',
-selectmode => 'single',
-scrollbars => 'ose',
)->pack(
-expand => 1,
-fill => 'both',
-padx => 5,
-pady => 5,
);
my $dir = q|/|;
readDir($dir);
MainLoop;
sub readDir{
my $dir = shift;
opendir(my $dh, $dir) or die "Can't opendir $dir: $!";
my @all = readdir($dh);
for my $x (sort (@all)){
next if($x =~ /^\.$/);
$tk{listbox}->insert('end', $x);
if(-d $dir.$x){
print "$x\n";
$tk{listbox}->itemconfigure($tk{listbox}->size()-1, -foreg
+round=>"#F00");
}
}
close $dh;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
