I am trying to write a GUI for playing Goe, which is a board game polular in east Asia. As I want the program be able to run on all OS platforms(at least on Linux and Windows) without modification, Perl/Tk seems to be the right candidate.

I encoutered a problem with getOpenFile( ), and I included reduced sample code at the end of this message.

getOpenFile() works fine for the 1st window, but if I clone a window, getOpenFile() will generate the following error:

Tk::Error: image "image1" doesn't exist at /usr/lib/perl5/site_perl/i386-linux/Tk/FBox.pm line 91.

(the above is the 1st line of the errors) which I tried to eliminate but didn't succeed.

I am running the code on Slackware Linux 7.1, Perl 5.6.0, Tk800.024.

Please try the following code and I am desperately in need of all you monks' wisdoms.

(If my English is not accurate, please forgive your eastern counterpart :-)

#!/usr/bin/perl -w

use strict;
use Tk;

my $FileName;

NewWindow( );
MainLoop;

sub NewWindow
{  my $mw = MainWindow->new;
   $FileName = "";
   $mw->Button(   -text    => "New Window",
                  -width   => 16,
                  -command => \&NewWindow )->
         grid( -row => 0, -column => 0 );

   $mw->Button(   -text    => "Select File",
                  -width   => 16,
                  -command => [ \&ChooseAFile, $mw ] )->
         grid( -row => 0, -column => 1 );

   $mw->Button(   -text    => "Exit",
                  -width   => 16,
                  -command => sub { $mw->destroy; } )->
         grid( -row => 0, -column => 2 );

   $mw->Label( -textvariable  => \$FileName,
               -width         => 50,
               -relief        => "flat" )->
         grid( -row => 1, -column => 0, -columnspan => 3 );
}

sub ChooseAFile
{  my $mw = shift;

   my @types = ( [ "All files ", '*' ] );
   $FileName = $mw->getOpenFile( -filetypes => \@types );
}
