With Tk::WidgetDump 1.37, recent debian i386 perl 5.14.2 and perl-tk
804.030, if a widget hasn't yet been packed into a parent yet then
WidgetDump prints a warning. Eg geom.pl below
perl geom.pl
then double-click on "label" line
=>
Use of uninitialized value in concatenation (.) or string at /usr/share/perl5/Tk/WidgetDump.pm line 312.
I think it's the GeomManager print. Perhaps that bit could watch out
for no manager.
#!/usr/bin/perl -w
use Tk;
use strict;
use Tk::WidgetDump;
my $mw = MainWindow->new;
$mw->Label(-text => 'hello');
$mw->WidgetDump;
MainLoop;
exit 0;
