Oh, and I should mention that I tried it using the $widget->SelectionOption() methods as well: 

#!/usr/bin/perl
use warnings;
use strict;

use Tk;
my $mw = MainWindow->new();
$mw->SelectionHandle( -selection => 'CLIPBOARD', sub { return 'clip' }
+ );
$mw->SelectionOwn( -selection => 'CLIPBOARD' );

[download]

It gives the same error (in xclipboard). :-( Whereas the following works just fine: 

#!/usr/bin/perl
use warnings;
use strict;

use Tk;
my $mw = MainWindow->new();
$mw->SelectionHandle( -selection => 'PRIMARY', sub { return 'clip' } )
+;
$mw->SelectionOwn( -selection => 'PRIMARY' );

[download]

Update: Hrm. Upon further testing, I find that the 'PRIMARY' selection was not actually working between applications. It owns the selection ok (ie, whatever was selected before, is no longer), and I can insert the selection properly within my own application but it does not show up in other applications.

Upon further further testing, I find that it all works just fine if I have a MainLoop in my program. Now all I have to do is find a way to get it to execute a single loop and then exit. I thought there was an easy way to do that but I cannot seem to find it. I can always resort to some chicanery involving $mw->after() ...

Does anyone know a function that will execute a single Perl/Tk event loop, and then return?
