In my callback I have a call to this subroutine:
sub ThumbNail {
my($name) = @_;
my $row = $img_id % 4;
my $col = $img_id - 4 * $row;
my $img = $frame->Photo(-format => 'jpeg', -file => $name);
my $iratio = $img->width()/200;
my $nh = $img->height()/$iratio;
my $newimg = $frame->Photo(-width => 200, -height => $nh);
$newimg->copy($img, -subsample=>($iratio, $iratio));
my $imgL = $frame->Label('-image' => $newimg)->pack;
$imgL->bind('<Button-1>', [\&doFocus, $imgL] );
$imgL->bind ( '<Key-1>' , [\&rate, $img_id, 1]);
$imgL->bind ( '<Key-2>' , [\&rate, $img_id, 2]);
$imgL->bind ( '<Key-3>' , [\&rate, $img_id, 3]);
$imgL->bind ( '<Key-4>' , [\&rate, $img_id, 4]);
$imgL->bind ( '<Key-5>' , [\&rate, $img_id, 5]);
@imgs[$img_id] = { name => $name, lbl => $imgL, sel => 0 };
$img_id++;
return $imgL;
}
Some command windows flicker and then it aborts. |
