Thank you for your suggestions. But I had already tried both your solutions and they did not work. See the following - code which I slighly modified to use your proposed solution \&subname, arg1, arg2, .. . PS: the code should print in the subrutine the variable $SomeVariable.
#!/usr/local/bin/perl -w
use Tk;
use Tk::DropSite;
use strict;
use vars qw($top $drop);
$top = new MainWindow;
$top->Label(-text => "The drop area:")->pack;
$drop = $top->Scrolled('Listbox',
-scrollbars => "osoe",
)->pack;
my $SomeVariable="xxx"; # The variable I want to pass to the subrutine
$drop->DropSite
(-dropcommand => [\&accept_drop, $drop, $SomeVariable],
-droptypes => ($^O eq 'MSWin32' ? 'Win32' : ['KDE', 'XDND', 'Sun'])
);
MainLoop;
sub accept_drop {
my($widget, $selection, $SomeVariable) = @_;
print $SomeVariable;#printing the variable passed from the main
my $filename;
eval {
if ($^O eq 'MSWin32') {
$filename = $widget->SelectionGet(-selection => $selection,
'STRING');
} else {
$filename = $widget->SelectionGet(-selection => $selection,
'FILE_NAME');
}
};
if (defined $filename) {
$widget->insert(0, $filename);
}
}
__END__

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).

or How to display code and escape characters
are good places to start.
