dir 2>&1 doesn't work in Windows.
cmd.exe /c dir does.
Following is my updated version. I also had to change
-text => $cmdLineText to
-textvariable => \$cmdLineText for the Label to see the changes in the variable.
use warnings;
use strict;
use Tk;
use Tk::Button;
use Tk::Checkbutton;
use Tk::LabEntry;
use Tk::Label;
my $cmdLineText;
my $mw=MainWindow->new(-title=>'Foo Installer');
my $row = 0;
my $w_install = $mw-> Button ( -overrelief=>'raised', -relief=>'raised
+', -text=>'Install', -command=>\&installItems) -> grid(-column=>0, -r
+ow=>++$row, -columnspan=>3, -sticky=>'nsew');
my $w_cmdWindow = $mw->Label (-height=>7, -foreground=>'white', -backg
+round=>'black', -textvariable => \$cmdLineText)->grid(-column=>0, -ro
+w=>++$row, -columnspan=>3, -rowspan=>10, -sticky=>'nsew');
MainLoop;
sub installItems {
open (FILE, "cmd.exe /c dir|"); #does something
$cmdLineText = "";
while (<FILE>) {
#chomp;
$cmdLineText .= $_;
}
close(FILE);
}

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).
