in reply to Perl/Tkx Mousewheel

In one of my programs i found this lines:

$mw->bind('<MouseWheel>', [ sub { my $wert = -($_[1]/120); $wert = '+' . $wert unless $wert =~ /^-/; animation_schalten($wert); }, Tk::Ev('D') ] );

Perhaps it helps?

    Using:
    $canvas->g_bind("<MouseWheel>", [ sub { my $wert = -($_[1]/120); $wert = '+' . $wert unless $wert =~ /^-/; print $wert . "\n"; }, Tkx::Ev('D') ]);
    just gives me '-0' all the time

      Note: I use Tk::Ev not Tkx::Ev. I don't know, but it might be a difference.
