Hi Jack,

you can use Test::More and a SKIP - block, then just test tkinit()

Christoph


use Test::More tests => 17;
BEGIN {use_ok ('Tk');
use_ok ('Tk::MyModule');
}

SKIP:{

my $mw = eval{ tkinit()};

skip 'Tk::MainWindow instantiation failed - skipping Tk-MyModule.t',
15 if $@;

## 15 tests

}#end SKIP


--
use Tk;use Tk::GraphItems;$c=tkinit->Canvas->pack;push@i,Tk::GraphItems->
TextBox(text=>$_,canvas=>$c,x=>$x+=70,y=>100)for(Just=>another=>Perl=>Hacker);
Tk::GraphItems->Connector(source=>$i[$_],target=>$i[$_+1])for(0..2);
$c->repeat(30,sub);MainLoop

Perfect! Thanks Christoph.

Do you know if Test::More a core module?

It was a core module beginning with 5.6.2:

C:\>perl -MModule::CoreList -e "print Module::CoreList-
>first_release('Test::More')"
5.006002
