( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hello all, I've got a random issue, that I'm having a hell of a time tracking down and am hoping someone can help or give a suggestion. The MListbox seems to work fine till it will randomly stop displaying results and I get the following error. Can't use string ("") as a subroutine ref while "strict refs" in use at /usr/lib/perl5/vendor_perl/5.8.8/Tk/MListbox.pm line 700. I've checked my returned results and nothing changes or is strange. Here is the section of code that is having issues. UPDATE: Upon further looking, a variable in the MListbox.pm becomes undef. Which I'm not sure how that's happening. Maybe someone who understands it more than I will know? The second section of code is taken from MListbox.pm. $code becomes undef.

my $searchRes = $top->DialogBox(-title => 'Search Results', -buttons => ['OK', 'Cancel'],) +; my @dispRes = qw(ID FirstName LastName); my $ml = $searchRes->Scrolled( qw/MListbox -selectmode single -scrollbars oe -font sm +all / )->pack(-expand => 1, -fill => 'both'); foreach my $colHdrs (@dispRes){ $ml->columnInsert('end',-text=>$colHdrs); } foreach (@dispRes){ push @row, $hash{$_}; } $ml->insert('end', \@row); $ml->see('end'); <-- Error get's thrown here print Dumper($ml->getRow('end')); $ml->update; my $answer = $searchRes->Show();
sub _selectionUpdate { my ($w, $code, $l, @args) = @_; ; if (@args) { foreach (@{$w->{'_columns'}}) { &$code($_->Subwidget("listbox"), @args); } } else { &$code($w->{'_columns'}->[0]->Subwidget("listbox")); } }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
