Thanks! The ...->interps ... works great on the Linux side with X11. Thought maybe there was a data structure in the Perl interpreter which could be queried for all of the windows so it was OS independent. Sounds like not. Appreciate all of the help!!! Thanks!
Re^2: TK Toplevel Window List
Replies are listed 'Best First'.
Finally was able to retrieve the window list from Perl
Win32 using some ugly code:<\p>
if ($^O eq "MSWin32")
my @pt = `tasklist /v`; # Get the process list from Windows (NT, 2
+K, XP, 7)
foreach my $p (@pt) # One process per line
if ($p =~ m/perl\.exe/ig) # Keep only the Perl processes
my @p2 = split(/\s+/, $p, 11); # Any space after 11 is par
+t of the window title
my $nm = $p2;
$nm =~ s/\s+$//g; # Remove trailing whitespace
# Use interps approach
