use threads; use threads::shared; use Tk; # If these two hashes are shared (as below), the Entry widget displays # "Original"; if they are not shared, the widget displays "Changed". # %top_hash; # %hash; share(%top_hash); share(%hash); $top_hash{A} = \%hash; $top_hash{A}{B} = 'Original'; $t = MainWindow->new()->Scrolled('Text')->pack(); $e = $t->Entry(-textvariable => \$top_hash{A}{B}); $t->windowCreate('end', -window => $e); $t->insert('end', "\n"); $top_hash{A}{B} = 'Changed'; MainLoop;
If %top_hash and %hash are shared (as above), this script displays an Entry widget which contains "Original". If those hashes are not shared, the Entry widget display "Changed." Why doesn't the Entry widget update its display when I set -textvariable to a reference to a shared hash?

In reply to perl/Tk Entry widget displays wrong value when -textvariable is shared by Smile-n-Nod

      Should cpanminus be part of the standard Perl release?
