Well this works for me on linux. I use ICEWM and the latest Xserver version. May say what Tk, distribution, Perl, and Xserver versions you have going.
Ugly.... but demonstrates it works.
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
my $types = [['Format Perl', '.pl']];
my $mw = new MainWindow ( ) ;
$mw->setPalette(background=>'black', foreground=>'white');
my @files;
$mw -> Button ( -text => 'Select File ' ,
-command => \&open_it
)-> pack(-padx=>5, -pady=>5) ;
MainLoop ( ) ;
sub open_it {
my $names = $mw ->getOpenFile (
-initialdir => '.',
-filetypes => $types,
-multiple => 1) ;
foreach my $file( @{$names} ){
print "Result ", $file, "\n" ;
}
}
